Crassula (identification) time

Post by MatDz »

It is high time to confirm or correct some of my labels,. I'll let myself start with Crassulas as some of them are in pretty active growth at the moment - joys of a tad lower temperatures and grow lights I reckon.

For the first round come two Italian beauties (as in "from Italian nursery", because both seem to come from Namaqualand actually), (I think!):

C. columella (https://www.crassulaceae.ch/de/artikel? ... C&aID=1103):

and C. elegans (https://www.crassulaceae.ch/de/artikel? ... E&aID=2703):

Thank you!

PS: I hope the title won't confuse too many people! :mrgreen:

Yes for Crassula columella, I am not sure about Crassula elegans - maybe a larger photo. However, the inflorescence looks like it.

Cheers,

Thanks!

I promise, the photo is huge! Try hovering over the lower left corner and centre- or right-click on the link there (or this might work directly: download/file.php?id=73403&mode=view).

PS: I know there is at least one mealy bug hiding on the very top of the stem on C. elegans (wannabe)!

I agree your columella looks OK Mat but the elegans isn't. Neither the stems or flowers look correct to me for pure elegans so I'd say you have a nursery hybrid.

That's absolutely possible (with 99% chance) - I still like it, though, will just need to find a few "pure" specimens later on!

I see you have a stowaway cactus seedling with the 2nd plant. I bet that wasn't on the plant passport.

Good eye! I don't recall any plant passport, but maybe there was something written on the "assorted cacti" label (or similar). I will worry about it later, it's still small so can use some extra water over winter I reckon, esp. while under lights.

The second photo isn't too clear but could be the hybrid Marchandii which I think is meant to be a natural hybrid.

I had C. marchandii (if we trust the labels...) from the same source (only for a brief period of time, it arrived in terrible state and even chopping it into pieces did not let me save any) and it had more prominent, pointy and upwards directed leaves, which matches photographs on ICN (https://www.crassulaceae.ch/de/artikel? ... M&aID=2676) and e.g. this one https://www.giromagi.com/prodotti/src/c ... _74681.jpg (well, now we know why they are "Italians").

I think I will put "aff. elegans" on it for my own needs, so I remember how to find where it might be coming from (winter rainfall west coast) and to give it a brief break in summer.

Edit: C. marchandii was also larger, while this one has less than 10mm in diameter, it had maybe 10-15mm.

Today I visited (as a part of the daily exercise dose) the Conservatory Archives which happens to stock Giromagi plants. They had plants both labelled as C. elegans and C. 'Marchandi' (and a few more, couldn't say no to a couple of Haworthia hybrids :oops: ), a comparison photo below. I'm pretty sure my "C. elegans" looked like that about half a year ago, I just skimp on water!

PS: I think the forum engine doesn't like portrait oriented photographs.
