Trich question

[WoodDragon]

Number one I have a dubious ID for, and the second I'm narrowing down. Number three I know but would like confirmed.

If it helps, the plant in photo 1 is pretty much the colour shown, but the second is a little more blue/silver than the picture shows. It's spines are brown-tipped and -based, and buff in the middles.

(Edit 2: Added more photos. Photos 4, 5 and 6 are of a plant identical to the cutting in photo 1; photo 7 is of a plant identical to the parent of the pup in photo 2; and photo 8 is 'very similar' to the parent of the pup in photo 3)

Hmm, not sure on either, but I am almost positive neither are Trichocereus sp. Quite interesting looking cacti.

Is it a Cereus species?

It's not a Trichocereus thats for sure.

[hebrew]

i gree with teotz here looks like a cereus, the second one that is

First one appears to be psilocerues sp, the 2 nd the top of cerues.

AFOAF told me that the first is a sideshoot from about 1.5m up a 2m column. The other two are both basal pups, not tip cuttings.

Curiously, the first one's mama was labelled as a trich, although there's always the chance that some member of the public played musical tags...

I'll try to get some photos of plants that resemble the parents - obviously I can't know who the exact parents are!

Third one looks very Tricho-like, I'm thinking maybe T. cuzcoensis, T. knuthianus or possibly T. peruvianus. Bit hard to be certain with such a small pup, but pics of the mother plant would be able to get you a decent ID.

Ace, you are on the money with the third one. It is T. knuthianus, or at least that's what its label says.

The first is supposed to be T. fulvilanus nigripilis. I can sorta believe it when you see the larger plant from a distance (photos 4-6), but looking at the cutting up close... well, I'm not convinced. The colour has definitely faded to a greener shade since potting, so maybe when it roots it'll change its morphology to that of a trich, but without a few definitively ID'd reference plants of the various genera I am left wondering. Being on dial-up I just don't have the time to download squillions of photos from the web with which to do comparisons.

The stumpy silver pup (photo 2) and its bigger version (photo 7) I am still scratching my head about.
