Cuzcoensis or Peruv?

[Eluna]

So ive got this lovely peruv *update* no, its a cuzcoensis!

BUT, i was wondering what these are? I know they are a bit unhealthy, but it doesnt matter.. I was wondering.. They were sold as peruvianus but im wondering what they actually are?

The one on the right is some pachanoi, the white bright color is the moisture reflecting from the flash as i took the pictures at night

and heres a close up

Any ideas?

Thanks guys!

None of them are Trichocereus peruvianus.

[Eluna]

Hmm... Interesting! as it was sold to be my someone on here as kk242

[tripsis]

Well, KK242 is the name for several plants, but most commonly KK242 is T. cuzcoensis, which I think your first plant is. Can you get us better pictures of it?

[Eluna]

okay, info: "kk242 (from sab)"

mother plant

[tripsis]

Well that's definitely T. cuzcoensis. Is that the same plant as the one in the first photo?

[Eluna]

Indeed it is! well, doesnt matter. Its definitelly the nicest looking of all my cactus!

[Evil Genius]

Well that surely disproves the Stetsonia Theory then! Very nice cactus, Eluna! I like the KK242 in my collection a lot too. Its such a strong cactus! bye Eg

[Philocacti]

T. cuzcoensis is a very attractive tricho imo

and it makes a perfect stock

I would say that the 4 mangled cactus cuts are peruvianoid, based on their side-profile (the sinuous side-profile), the areole size (nicely big and grey), and width of the v-indentation (quite long). The cross-section is also peruvianoid, as the cusp of the rib margin is very sharp (whereas a pachanoi is a lot less sharp). I don't know much about Aussie Knuthianus, but I'd conjecture that if this is indeed an example - then AusKnu is peruvianoid too. :]

The spination though, is a bit strange, it makes me think the plant definitely is hybridized.

bm, search aussie knuthianus on this site, theres a few threads..

Somebody pass me a grusonii, I believe it's time I ate one

[tripsis]

What's your address? I'll express post you one.

[CβL]

Okay, I've had a pretty good look, but I'm still not 100% convinced (about 90%). That second close-up photo looks so much like a peruvianoid, sort of like this one (SS01): http://i221.photobucket.com/albums/dd59/teotz/cactus044-1.jpg

This just seems to have a slightly different tip: http://www.shaman-australis.com/forum/index.php?app=core&module=attach&section=attach&attach_rel_module=post&attach_id=19501

-3 for "Toldja"? Aw come on guys! Hahaha

Nope, not peruvianoid, its a cuzcoensis var.

Yep, agreed. I think it was Backeberg who mentions the synonymity of T. knuthianus with T. cuzceoensis...or maybe it was Ritter. I'd definitely say that there is good reason to call it the "Aussie knuthianus" as it is a bit different than T. knuthianus I got from both NMCR and Sacred Succulents, both of which are more similar to your average T. cuzcoensis, but still a bit distinct.
