Name those cacti... any ID'eas?

[Optimystic]

I've got a few I am unsure about and would appreciate any feedback on these

#1 I have no idea what this guy is... I got him over a year ago and repotted right away - he didn't grow all year.
at one point the ribs seems to get a little fatter in the body, but not at the tip... but back the same over winter...

#2 This guy came to me unlabeled... I wasn't gonna post this one at first and wait to see him grow
a little first, but I figured maybe someone has an idea... Was simply listed as "Purple Cactus".. its a columnar

that shows alot of purple... I know any cactus can with alot of sun but this one seems one seems more prone
to purpling... I found a link one time about another south american columnar turns purple often and looked similar..

I've spent alot of time searching for that link to no avail... It definitely wasn't a tricho, strange name I recall...

#3 This guy came to me mislabeled... I have an idea of what he might possibly be but the plant I suspect

is not easily identified so I would love to know for sure ... any thoughts appreciated

One is probably Neoraimondia herzogiana and two and three are probably both Stenocereus Griseus. The purple coloration on pic two is typical for it and so is the Spination and the greyish color on pic three. bye Eg

Thanks EG... on #1 I think you came very close if not on the money... I think if mine grew finally It would look like that just the spines are very aged... if only I can find out why he hasn't grown.. he's been watered and fed like all the others and plenty of sunlight..maybe he'll wake up now??? I wonder if maybe I packed the soil too tight and perhaps I should repot I dunno... It was one of the first cacti I ever potted and I didn't even breakup the rootball I just made a hole and packed the soil tight and later I read that its better to leave the soil a bit loose... they're supposed to be fairly fast growing from what I read and so Im now convinced that I should repot and maybe try a new soil or something

on #2 and #3 Im still a bit confused but I think you are very correct by saying they are in the Stenocereus Family especially by the spinage... #3 was actually labeled "Stetsonia Coryne"! but im sure its not a Stets.... I do wonder if #2 will look alot like #3 when he gets older but these two were grown together in the same backyard before they got here so I suspect they may be different plants, though time will tell...

Thanks for your suggestions Whether they end up looking the same or different i'll update if I can find this post again at the end of the season... im really curious about new tips forming out of #3 and that might at least tell me if these are the same or not... I just happened across a site by accident yesterday and found a pic of Stetsonia Gummosus which reminds me alot of #2... anyways good calls and thanks for your feedback EG

1 Not sure new growth would help, looks dehydrated, if it hasn't grown I would uproot it and check the roots for pests or rot.

2 looks a bit like Stetsonia Coryne, it tends to go strange cours under heavy sun or stress, much like the tip of your plant.

3 Cereus Peruvianus

Hi Hellonasty, stetsonia coryne does not develope reddish growth like that. Spination in number three does not fit Cereus Peruvianus but i know where you´r coming from as it is extremely dehydrated. Its most likely a Stenocereus. bye Eg

I have to agree with EG on these... I don't think it looks anything like a stets and has some very Stenocereus features @ 2
Regarding #3 I originally thought might by fimbriatus/hystrix due to this pic http://www.shaman-australis.com.au/gallery2/albums/userpics/S_hystrix_C.jpg but I am pretty sure its not a cereus
but now I think both of those are possibly Griseus with big spines... but possibly one of the other types of cereus, there are a bunch
but so far I think the spines scream Stenocereus on 3

the reason I think they are different plants is that #2 is obviously a clumper... the plant had 3 basal pups before she removed him from the ground and that little one is one of the pups... whereas #3 I saw a pic of in the ground and had no basal pups and from memory when perviously offered I don't remember any either but I certainly could be wrong... but I do think the plant was in low sun conditions causing the tip to lean that way... it was originally listed as a purple cactus and she told me its not so purple anymore because not getting enough sun in her front yard lool

#3 is a plant that the lady got from a neighbor but since that lady was out of town she pulled her own plant out of the ground... she also had to chop the roots off cause it started to rot go figure... could have something to do with the dehydration but this lady's plants are usually very well hydrated and plump

I just got 2 and 3 in the past week or two... thought number 1 has me stumped with lack of growth... but I don't think he's too terribly dehydrated, though he is a little, winter just came to an end here... last season when he hydrated the ribs just got a little fatter and only in the body of the plant but that appears to be normal in the plant that EG identified as a possibility

I put him where he woud get some morning sun and he got some ugly burn :| what a terrible cactus father I am ... bleh... anyways... I'll repot #1 for sure but I think EG is on the money with 'Neoraimondia Herzogiana'... This pic has me convinced the EG made the right call on the first one http://cactiguide.com/graphics/n_herzogiane_600.jpg
