Trich question

What are the diagnoses me hearties?

Photo 2

Photo 3

Photo 4

Photo 5

Photo 6

Photo 7

Photo 8


Photos 4, 5 and 6 (the 'Y'-shaped one) are of a plant identical to the parent of 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 identical to the parent of the pup in photo 3.

Sorry about the size of the last one. It obviously didn't resize to the same extent as the others . For those who had the patience to wait for it to download, it is the dark green cactus in the forground, not the ones easily seen behind in the top left of the frame.

Oops )

Hey WoodDragon,


It would be best if you did post the images here because not all members have access to that site.

They are both Creoids and as such are difficult to ID. I think the first one is Cereus Repandus and the Second Cereus Peruvianus altho it could be Jamacaru as they are almost identical.

As for the colour Cereus SP tend to change their colour based on environmental conditions. Some are a grey/blue and some deep or light green depending on the climate and environment.

Is this a trick question?


Sorry I couldn't resist.

Yes, it is a trick question!

The first is labelled (by professional botanists) as a trich, although I've been sceptical and because of the almost aquamarine colour I'm leaning in the same direction as HN and thinking Cereus or Pilocereus, and the second I too assumed to be C. peruvianus, although I'm not yet convinced.

Here is a trich, though...

i am not sure of the first one, but the second looks like maybe stenocereus to me. the spines in stenos are often white-gray, but sometimes have a brown tint.

i doubt any of those are C. peruvianus or jamacru. these 2 are fairly similar, but note really that close to those i think.

here are a couple pics of C. jamacaru



and a steno that looks similar to me, but surely not the same



the third one, i got no idea either, its pretty tiny and barely even has ribs...gotta let that sucker grow

Thanks for the photos kada, especially the steno. It's not the same as mine as far as I can discern (which, with cacti, doesn't mean much at all!), but you might be on to something.

I visited the parent plants and took some photos today: when I have some time after the Fathers' Day stuff is over I'll shrink them and put them up.

The first pup is from a cactus that is definitely labelled as a Trichocereus. It is growing right next to some Cereus, and seeing them standing together it is apparent that it is not C. peruvianus. I'll leave putting the labelled name up for a bit yet, just so that I can get a few more unbiased best-guesses.

The second pup unfortuantely has no name, but it is in the trich part of the bed. I'm still not convinced that it's a trich, but wait until I put up the photo of the parent.

I think you'll get the third one easily when I put up a photo of the taller columns!

Both those plants are very small, they could be any number of different species. Once a plant has grown to a mature size it is much easier to identify. Photos of large plants showing growth habit, flowers and fruit will get you an accurate response. I have a bunch of plants at home I've only had identified as far as the genus, and others not even that far. I'm slowly growing them on without knowing what to expect, once they've flowered I'm going to try and find out what species they are. I kind of enjoy not knowing, it makes for all sorts of little surprises.

The original post above has been edited to include some photos of plants 'very similar' to the parents.

For those who have been wondering, the plant in photos 4, 5 and 6 is labelled T. fulvilanus nigriplis, and the one in photo 8 is labelled T. knuthianus. The first ID I am dubious about, but the second seems reasonable.

Still clueless about 2/7.

Thoughts about any of them?

number 8 is T. knuthianus for sure WD.

looks like a very nice collection. Where abouts???

The photos of the cacti that are like the parents of the cuttings I got from a guy in the pub, were taken at the local bot gardens.

Same bloke tried to give me a dirty great black egg...

The collection is not bad, but they take the arid thing to extremes, and I doubt that the plants are ever watered. They also seem to be a bit wanting for nutrients. It could just be that there are a few panes missing that probably let the cold winter air in, but I have never seen any sign of any care so I reckon that is not just a matter of a lack of glass.

For the curious Pete's patch is directly behind the back wall.
