How to recognize Trichocereus Terscheckii & Pasacana

Question

I wonder what would be the main characteristics of these fatty trichs, as well as other similar trichs of the fatty 'family'...

They grow more slowly than the fast growing trichs, I know that. They have more dense and long spination than pachanoi family. What else?

I am supposedly growing both species, so it should be fun :)

The Culpinensis is a nice cactus, Michael. I planted some of the seeds too but it was too old so i didnt get more than one germination. And the one who germinated was sick right from the start so unfortunately i dont think i´ll be able to get plants from em. I still kept the container though.

Funny that you mentioned Trichocereus Taquimbalaensis v. wilkae. I was just browsing one of Ritters indexes and he mentioned it to be synonymous with Trichocereus Tacaquirensis. Its the field number FR72.

I dont know where the name Trichocereus Culpinensis came from but im pretty sure its one of the nomen nudums that Karel Knize "published". Knize once sold a Trichocereus Tacaquirensis v. Culpinensis KK924. It was collected in Culpina, Bolivia, 2800 m. I´ll doubt he has any taxonomical system what makes this one Culpinensis. Its just one more variety that can be sold to customers. You know, knize sometimes relabels old KK numbers to increase the sale. So it could be that he sold that seed under diffrent numbers. bye EG

tripsius, like many of the "giant" cactus it simply changes with maturity.

Here's the notes from my cactus collection listing...

T. culpinensis – from Aztekakti – seed sow on 1-15-99 – Bob Ressler states, “KK924, Culpina, Bol. 2800m variation of T. tacaquirensis (aka T. taquimbalensis)” – matches Backeberg’s T. taquimbalensis v. wilkeae.

tripsis the seeds came in a 7 species trichocereus seed pack, [nomad botanicals usa 2008].

of those only 5 species germinated, and the ones we're talking about were labeled as wendermanianus. what came as pachanoi grew to be peruv/macro and what came as peruv were cuzco, bridgesii were right , terschecki were right too

I cannot believe the plants in pichaels pictures, in pics 2 are the same species with pic 3! they look so different, while I could believe my plants is the one in pic 3.

Your seed grown also seems to have [compared to my specimens]:

more symmetry in the spine arrangement, less wide ones and only traces of naughty curving seen in upper spines. Do you have any more pictures of this plant, Michael? 8 ribs or 9? But I guess different conditions, sun etc could also play part... and the plant sure matches.

I got another [kk ??? seed grown from sab, also as wendermanianu] which is pretty closer to yours than my biggy one, 'efi'. This KK one has also traces of 'naughty' curves and more symmetry.. will post photo soon

Mutant, I can assure you these are all the same species regardless of the appearance of the taller columns, but clearly, just like in other species, there is going to be variation. Have a look at SagtaCactus' photostream to look over more pictures of the plant (which he calls T. werdermannianus).

So I was walking to town just now, and I walked past an antique shop and glanced into the window. Sitting in glass fish bowls with a thick layer of perlite, was a Trichocereus werdermannianus/chiloensis plant, and a Trichocereus cuzcoensis. Strangest of all, there was red twine tangled around both plants - probably some attempt to make them more "arty".

Heh.

P1060524.jpg

taquibalensis var. wilkae 'efi'

P1060525.jpg

taquibalensis var. wilkae 'efi' at the left and 'KK 10911 wendermanianus' obviously a taquibalensis too without the overly curvy spine , seed grown from SAB at the right

P1060526.jpg

front row:

unknown, chilensis big , chilensis small

the unknown at first I thought/hoped it be terscheckii, then I thought it might be tquibalensis. still unsure

it might be the same with the unknown biggy and fatty at the right [whitish spines]

the rest [middle] are terschckii

No wait, both (small one on the left and the fat one with the white spines on the right) are probably diffrent forms of Trichocereus Candicans if im seeing it right. Could you please post a closeup because i wanna have a better look at the spines? But im actually pretty sure because Candicans is very variable.

you're probably right I was thinking trichocereus candicans for the left one but not remembered the name. I got some older candicans and they are very different from the fatty on the right.

the one on the blurred background, below the penis plant with the portulaca succulent with the orange flowers , must also be a suepr spined form of candicans

will take close up shots

PS: maybe we should be pinning a thread about taquibalensis, terschecki, wendermanianus, validus etc phenotype? this has pretty nice photos and discussion!

The group that surrounds these cacti is so messed up that its a little bit more difficult than with the other ID Threads. But i might be pinning it but i first wanna have a look at other possible Threads that could be merged into it. Please post some closeups for the one with the white spines. It reminded me about Trichocereus Albispinosus but its a nomen nudum and im pretty sure its a synonym for a certain Candicans Variety. But it could as well be from the Tacaquirensis/Taquimbalensis Group so i would like to have a closer look.

hey here are the close ups

P1060563.jpg

T.candicans , I suppose, the spines are not usually that long In all types though,,,

P1060561.jpg

the fatty white spined one. I note that when I first put up this for ID, some dude said it might not even be a trichocereus, but it remained a mystery without much suggestion for what it is

P1060562.jpg

The supposed small candicans. It was a bit in bad shape when I got it, but thinking about it, this has been a slow grower whereas candicans is super fast. Could it be something else? I think yes...

No first and last one are Candicans for sure. The one with the white spines should we take out for now but i am actually pretty sure its definately a Trichocereus. The name Pasacana pretty much popped in my head when i saw it.

compared to the pasacana I have seen

lots less play and curves from spines also a more symmetrical spination I think

pasacanas IO have seen range from light yellow to intense orange yellow and to reddish brown, but they dont seem to fade with time to white.

but maybe indeed this is some white spined form of pasacana. Thanks!

Changed my mind about the second one. Put my glasses on and agree it is probably neither a Pasacana nor Trichocereus. I would say its a Soehrensia Formosa. http://imatani.com/Soehrensia.htm

They belong to Echinopsis now.

I bought these cacti in May at nurseries in Northern California.

First, labelled T. Werdermannius:

Third, labelled Trichocereus:

Fourth, labelled T. Terscheckii;

The third looks like T. Candicans to me; do the others seem correctly identified?

Thanks

thanks EG, will be considering this

johnny the 2 terscheckiis look pretty correct

the "trichocereus" could be terschecki, validus or .... ?

and the wendermanianus is considered by some people needless as a name - what it might be, tquimbalensis/taqaquirensis in the spine formation and fattiness [its no cuzco], but the whitish in spines make me think it might be chilensis...

awesome finds, now you got something to wait for , for the next say 50-60 years!

I'll be 100+ in 50-60 years but I'll be happy if my Werdemannianus looks like this one near my home at the Berkeley Botanical Gardens.

for some reason I thought I had already replied here.

anywayz, no need to be so hard on yourself, I am not so young anymore myself, but I can dream, cant I? so I dream that some terscheckii I grew from seed will surpass my own height... ambitious I know... and I will be a bit less than 100 in 60 years...

ALSO, 'werdermanianus' [taquibalensis is the one I got more experience with], not sure if there is any real differance between them] grow much faster than , say terscheckii... .

wanna see how fast??? [regarding taquibalensis]

P1070746.jpg

this girl here [yeah, I named a trichocereus with a girl name] , "EFI" is 4+ years old from seed!

and so is this dude here

P1070747.jpg

of course, the second one was not grafted when young , hence the difference in size and growth.

I even rooted a pup from EFI and it rooted easily

dont treat them as slow growers when they grow, especially the taquibalensis forms. when in growing season, give'em plenty of water just as with the other columnar trichocerei....

P1070748.jpg

also, some terscheckii

front right , below right are 4 y.o. from seed , the one in the back got 10 ribs

at the left it came as a trade from UK

PS: yeah, I know I got a sexy leg! :)

My tiny Werder seedlings, love the length of the spines on the tips.

A few years before they get to EFI's size, hope I get to see it happen!!

Trichocereus taquimbalensis var wilka , same seed grown batch. on the right is var I named EFI this began its life grafted on a pereskiopsis and is really more forward/advanced than the others. The specimen shown is a cutting took from the mother plant, the mother is pretty fattier and with more ribs. I am not sure if the phenotype is characteristic of that seed dna or the grafting affected it. The one on the left had the less number of ribs from start, is beautifully dark green and has awesome spine pattern. A true var wilka too. I got a couple that aint so wilka, and I am growing several names of the family from scratch again. Age: 5 years from seed.

P1090990.jpg

This must be Trichocereus validus after all, so the initial guess sounds just right.

P1090997.jpg

And this, judging from the new pup seems again like the initial estimation : T. terscheckii

P1090996.jpg

these were a freebie pack " validus / mixed ??? " from a good community friend.

I have not grown validus yet, these seem to be pumping pretty faster than any that I have seen. Should validus seedlings go this fast? Interesting is that from that seed batch has occured a slow growing cresty form.

P1100002.jpg

background taquimbalensis

middle row: terscheckii, 5 years from seed

below row: pasacana

P1100007.jpg

A pasacana looking good in that over planted pot

same as previous, different perspective

Hey thanks mate!

it is the BIG one I had cut , before, most guesses were saying terscheckii, but since I saw the new growth getting bigga , the cactus started saying pasacana. cool we seem to agree.

[ the rest of the cut pieces have been a bitch to root, no success yet!!! ]
