Hi all,
I am looking for a good trich. key. I found one referenced
in the historical boards but the links are broken. I know
there is probably and good thread on this topic but I can't
find it.

Was just hoping someone could point me in the right direction.

Thanks,
P

A Key to Distinguishing Trichocereus Species

What's Related >>
Step by step procedure for determining what Trichocereus you have

The Trichocereus Key

STEP 1

Are the stems basically erect and "more or less" branched? If yes, go to Step 1.1

Are the stems "simple", low to the ground and growing in clusters? Go to Step 2.1

STEP 1.1

Are the limbs of the flower broad? Go to Step 1.1.1

Are the limbs of the flower narrow? You have a TRICHOCEREUS FASCICULARIS (aka Weberbauerocereus fascicularis).

STEP 1.1.1

Are the joints relatively slender, 2 to 3.5" (5 to 9cm.) thick? Go to 1.1.1.1

Are the joints stout (sturdy)? Go to 1.1.1.2

STEP 1.1.1.1

Are the ribs scored by longitudinal furrows between the areoles? Go to 1.1.1.1.1

Are the ribs NOT scored by longitudinal furrows between the areoles? Go to 1.1.1.1.2

The comments below are my personal observations/opinions based on young, seed grown plants. v. "Ancash": Similar to a "KK242" but the "V"-notches are much subtler, often not visible at all. Presumably from the Ancash region northwest of Matucana. v. "Blue": Lighter in color ("bluer"), areoles seem further apart (i.e., where in a certain distance a "KK242" has 4 areoles, the "Blue" has only 3). v. KK242: Seems to fit the standard T. peruvianus ID.

Presumably from the Ancash region northwest of Matucana. v. "Blue": Lighter in color ("bluer"), areoles seem further apart (i.e., where in a certain distance a "KK242" has 4 areoles, the "Blue" has only 3). v. KK242: Seems to fit the standard T. peruvianus ID.

And while I'm adding some Trichocereus information, some alkaloid info might be worthwhile to the thread.

Cactaceae Alkaloids. X1,. Alkaloids of Trichocereus

Species and Some Other Cacti

Scanned without permission by Debaser

Box 6804. 113 86 Stockholm. Sweden

ABSTRACT.- The alkaloids of 14 % species of Trichocereus are reported. Eight different previously known phenethylamines viz. tyramine. N-methyltyramine, hordenine. 3-methoxytyramine. 3.4-dimethoxyphenethylamine. N-methyl-3-methoxytyramine. 3hydroxy-4.5.dimethoxyphenethylamine. and mescaline were identified in these species. Mescaline was found to occur in T. cuzcoensis. T. fulvilanus. T. taquimbalensis and T. validus. Mescaline was also present in small amounts in Stetsonia coryne together with traces of anhalidine and anhalonidine. 3-Hydroxy-4-methoxyphenethylamine is identified in a plant, Pachycereus pecten-aboriginum, apparently for the first time. The commonly occurring isomer 3-methoxytyramine was found to be the major alkaloid of Trichocereus cuzcoensis. A tetrahydroisoquinoline alkaloid, anhalidine, was isolated from Pelecyphora aselliformis.

Results reported in a previous paper, indicated that the occu rence of alkaloids in Cactaceae was common (1). The basic alkaloids in 21 species of cacti mainly belonging to the genera Trichocereus, Helianthocereus and Cereus were reported in part I of this series (1). The structures of those, at that time,


FIG. 1. ldentified alkaloids.

known basic cactus alkaloids were also reviewed (I). Since then salsoline has found to occur in Echinocereus merkeri Hildm. (2) and N-rnethyl-4-hydroxy-3-methoxyphenethylamine in the peyote cactus (8).

The present report is concerned with the identification of alkaloids of cacti belonging mainly to the genus Trichocereus but also alkaloids of Stetsonia coryne, Pachycereus pecten-aboriginum, Pelecyphora aselliformis and Echinopsis rhodotricha.


EXPERIMENTAL

PLANT MATERIAL.-The cacti used in this investigation were obtained from the following

sources: Stetsonia coryne, Pachycereus pecten-aboriginum, Trichocereus cuzcoensis,

T. santiaguensis, T. strigosus, T. thelegonoides and T. thelegonus from W. Haage, Erfurt, DDR; T. courantii. T. knuthianus. T. rnanguinii, T. pupureopilosus, T. taquimbalensis and T. tunariensis from H. van Donkelaar, Werkendam, The Netherlands; Pachycereus pecten-aboriginum. Stetsonia coryne, T. santiaguensis. Echinopsis rhodotricha and Pelecyphora aselliformis from K. Edelmann, Reeuwijk, The Netherlands; T. fulvilanus, T. santiaguensis and T. skottsbergii from M. Schleipfer, Augsburg, DBR; T. validus, T. thelegonous were gifts from Dr. J. P. M. Brenan, Royal Botanic Gardens, Kew, UK.

The nomenclature of species as proposed by Backeberg (4) is used. Plants were checked to conform with the macromorphological descriptions given by Backeberg. (4). Reference caccti are maintained in our greenhouse.

ISOLATION AND IDENTIFICATION OF ALKALOIDS.- Methods for isolation and separation of alkaloids have been described earlier (1). The basic technique by which the alkaloids were identified has been fully outlined (1). In essence, the naturally occurring compound was considered as identified, if it showed the same chromatographic behaviour as the reference compound (i) on two gas chromatography columns (SE-30, XE-60, or JxR); (ii) by tlc |chloroform- ethanol conc. ammonia (85:15:0.4) or, for phenols, chloroform ethanol diethylamine, (85:5:10)| and (iii) by gas chromatography- mass spectrometry (glc-rns), giving the same mass spectrum as the reference compound. In addition to the previously used 5% SE-30 and 5% XE-60 columns, a column (6 ft X 1/8 in.) of 3% JxR on Gas Chrom Q (100 120 mesh) was found to be in some ways superior (Varian model 204 or 2100 Aerograph). Preparative glc was carried out using columns of 5% SE-30 on Gas Chrom P (Varian model 202 Aerograph).

SPECIAL CHROMATOGRAPHIC SYSTEMS.- 3-Hydroxy-4-methoxyphenethylamine, the isomeric 4-hydroxy-3-methoxyphenethylamine ("3-methoxytyramine"), and the purified phenolic alkaloid fractions of T. cuzcoensis and Pachycereus pecten-aboriginurn were chromatographed on Whatman no. 1 paper with n-butanol-acetic acid -water (4:1:5) as solvent (13). After spraying with Gibbs' reagent, reference 3 hydroxy-4-methoxyphenethylamine (Rt. 0.45) and the major phenolic alkaloid of P. pecten-aboriginum showed a blue color while the isomer 4-hydroxy-3methoxyphenethylamine and the major phenolic compound from T. cuzcoensis (Rt. 0.45) developed a brown cotor, Gibbs' reagent: 0.1% solution of 2,6-dichloroquinone chlorimide in ethanol followed by 10% sodium carbonate in water.

Reference 4-hydroxy-3-rnetboxyphenethylamine (Rf. 0.60) 3-hydroxy-4-methoxyphenethylamine (Rf. 0.45) and the two isomeric compounds isolated from cacti were well separated by tlc on silica gel G plates with chloroform ethanol diethylamide (85:5:10) as solvent (10).

The identity of 3-hydroxy-4-methoxyphenethylamine and the major phenolic alkaloid or P. pecten-aboriginum was further confirmed by glc using trimethylanilinium hydroxide (5) for on-column methylation of the phenolic groups. In both cases a major compound having the retention time of 3,4-dimethoxyphenethylamine was formed.

RESULTS AND DISCUSSION

Our present screening for cactus alkaloids has largely been motivated by the search for biosynthetic intermediates in the formation of mescaline and related tetrahydroisoquinolines. Indeed, three phenolic'alkaloids, 3-rnethoxytyramine (4-hydroxy-3-methoxyphenethylamine), 3-hydroxy-4,5-dimethoxyphenethlamine and 4-hydroxy-3,5-dimethoxyphenethylamine were identified in cacti (3) and were later shown to be true biosynthetic intermediates (9). Still, some plausible progenitors of the tetrahydroisoquinoline skeleton are lacking. Partly, using "mass fragmentography" (7) to simplify the search for likely, presumably phenolic phenethylamine intermediates, a number of the Trichocercus species, and other cacti listed in table 1 were investigated. Some results with biogenetic implications are reported elsewhere (8). The identification of alkaloids has now been verified mainly by glc-ms and the final results reported here (table 1

Earlier, we have investigated (1) twelve species of the genus Trichocereus, which according to Backeberg comprises in all 38 species. We have now (table 1) examined the alkaloids of 14 more Trichocereus species and identified, in all, eight different phenethylamines (table 1). These are previously all known (1) to occur in the genus Trichocereus, except N-methyl-3-methoxytyramine (N-methyl-4-hydroxy-3-methoxyphenethylamine), which is known only from peyote (8). Mescaline, previously isolated from five Trichocereus species (1), is now identified also in T. cuzcoensis, T. fulvilanus, T. taquimbalensis and T. validus. While it occurred as the major alkaloid in T. taquimbalensis and T. validus, mescaline was only a minor constituent in the two other species. It may also be pointed out that the alkaloid-rich T. cuzcoensis contained 3-methoxytyramine as the predominant alkaloid. The macroscopic appearance of the new mescaline-containing species resembled markedly the previously known species and in fact, based on their appearance they were predicted to contain mescaline.

Stetsonia coryne has previously been known (11) to yield the quarternary alkaloid coryneine (N,N,N-trimethyldopamine). The occurrence of tyramine and N-methyltyramine. plausible biochemical progenitors of coryncine, was thus to be expected (fig. 2). Furthermore, plants from three different sources of this species, which is a not too distant relative of the Trichocereus species, were found to contain beside two other simple phenethylamines small amounts of mescaline. Traces of two phenolic tetrahydroisoquinoline alkaloids, viz. anhalonidine and anhalidine were also identified.

Pachycereus pecten-aboriginum was already in 1929 by Späth and Kuffner (14) shown to contain carnegine. This cactus has now been found to contain several alkaloids as will be reported in a later publication. However, the major compound of the phenolic alkaloid fraction turned out to be a hydroxymethoxyphenethylamine, but surprisingly not the commonly occurring 3-methoxytyramine (4-hydroxy-3-methoxyphenethylamine), but rather the isorneric 3-hydroxy-4-methoxyphenethylamine as described in the experimental section. This latter compound might theoretically be a good precursor of some tetrahydroisoquinoline alkaloids, e.g., carnegine and salsolidine, since it may provide an advantageous para-activation for the ring closure. Experiments on the biosynthesis of carnegine and salsolidine in Carnegiea gigantea have, however, not entirely supported such assumptions (6).

Pelecyphora aselliformis has been reported to contain alkaloids, probably tetrahydroisoquinoline alkaloids. This is now found to be correct with the identification of anhalidine in addition to the ubiquitous hordenine. The structure of one major alkaloid of this species still awaits elucidation. In this connection, it is known (12) that cacti of several genera of Cactaccae, among them pelecyphora, in Mexico are popularly, although for unknown reasons, classed as "peyote". Possibly, the alkaloids of P. aselliformis are responsible for its classification as a "peyote".

Echinopsia rhodotricha was earlier reported (1) not to contain detectable amounts of alkaloids. From a large amount of cacti we have now isolated small amounts of hordenine and tyramine.

Ok, But how do I get to Trichocereus, and rule out other columnar cacti????




Here's some other info I've had saved taken from different parts of the internet. Sadly I don't have the links, just the copied information I saved.


The only cactus genus that is more confusing than Echinopsis is that of Opuntia. In both cases, there is a great number of species (over 100) and a tremendous amount of variation. In Echinopsis plants range from very small, flattened-globose plants to quite large, treelike giants. As a result, there is a long list of synonymous names for many of the species. Some synonyms referring to other synonyms that refer to a subspecies of some seemingly distinct species. Sorting through these names often feels like a wild goose chase and is quite frustrating.

In more recent thinking, the previous two genera of Trichocereus and Lobivia are included with Echinopsis. However, it is not at all uncommon for enthusiasts to use all three names in discussion even if their labels read Echinopsis. This usage reflects the general (inexact) situation that the larger, columnar members are distinguished as Trichocereus while Lobivia includes a select group of smaller, not-as-spiny plants which typically flower from low on the plant similar to most Rebutia species. This leaves the bulk of plants referred to as Echinopsis to be mostly spiny, ribbed, globose plants.

The main factor that ties these plants together are their very large, showy flowers. These flowers are all very similar in structure – funnel shaped, with hairy/wooly scaled floral tubes which give rise to hairy, globular fruit filled with a soft, mushy pulp. The flowers seldom last more than a single day and may be diurnal or nocturnal depending on the species. These species hybridize easily and have resulted in a tremendous number of hybrids that some cactus growers specialize in or grow exclusively. There are certainly enough hybrids to keep even ardent hobbyists busy.

Because of their exceptional flowers, many Echinopsis species are found in garden centers and collections world-wide. The larger species (aka Trichocereus) are also popular landscape plants in warmer parts of the world. While there are a number of species common in cultivation, there are as many or more unknown hybrids in the trade. These hybrids are easy-to-grow and produce nice flowers, but buyer beware if exact names are desired. Plants of this genus are widespread throughout South America and inhabit a wide range of habitats and climates.



CACTACEAE FAMILY

  • All but one cactus species is endemic to (occurs naturally only in) the New World
  • All cacti are succulent (have water-storing tissue), but not all succulents are cacti (e.g., Sotol). This sometimes makes it difficult to distinguish cacti from other plants that convergently evolved (developed similar characteristics due to experiencing similar environmental constraints) with cacti (e.g., Ocotillo).
  • To be a cactus, the plant must have the following set of characteristics:
  • areoles: structures from which spines, branches, and flowers come.
  • flowers with many sepals and petals that intergrade with each other.
  • flowers with many stamens.
  • flowers with multi-lobed stigma.
  • Most cacti use CAM (Crassulacean Acid Metabolism) photosynthesis, taking in carbon dioxide at night instead of the day to save water (evaporation rates are lower at night generally), storing the carbon dioxide as an acid, and then releasing the carbon dioxide during the day for photosynthesis.
  • Columnar cacti, with leguminous trees, characterize the Sonoran Desert
  • Besides columnar cacti, other major groups include barrels, hedgehogs, pincushions, chollas, and prickly pears.


I know that doesn't answer your question exactly, but you'll most likely have to buy a cactus ID book or search the internet for more information, you've tapped me out.
