Trichocereus ? Solved

[Guest]

Hi,
This and the rest came as a packet of Trichocereus pachanoi - anybody know what they are?

Is it columnar or globular?

Ian,

It looks to be columnar but stocky

One feature that should be present on any T. pachanoi is the horizontal groove above each areole. I see it on some, but not all, of the plants in your other message.

Another thing to consider is that some authors combined T. peruvianus and T. bridgesii with T. pachanoi as a single species.

This page contains a key (you'll need flowers!), but also summary descriptions for each Trichocereus species.

Hi Bob, the first one is a Trichocereus macrogonus. Here you have a site that helped me alot about columnar Trichosereus and Cereus..

Krister,

Thanks for this site, I seem to have loads of pachanoi and peruvianus both are great for grafting then I have a long spined peruvianus type which does not fit at all but I will keep a couple.

My aim is to get some of these to flower so that I can raise my own (reliable) grafting stock seed.

On the grafting front I have found peruvianus a better stock than pachanoi for two reasons pachanoi seems to be more fibrous and is more prone to offseting that peruvianus. This is just my findings and as usual others will find other results.
