Two columnars I can't figure....

Post by Dixie Chicken »

I have two columnar cactus that I've owned for a few years that I can't solidify an ID on and am hoping someone will have some suggestions.

The first came labelled as Lemaireocereus chende. I believe it should be a Pilosocereus now and I also understand they are a bit unusual in collections. Since I purchased it from a major discount chain, I'm not too hopeful that is correctly labelled. From all descriptions I've read it seems that my plant's spines are not correct, although the rib count is within range, the color seems appropriate and it even curves slightly! But the spines seem way too long. Any help would be appreciated.

The second had been tentatively ID'd as Pilosocereus pachycladus, but I have another plant that seems correctly ID'd as that, that has flowered at 1/2 the size and the flower seems to match up correctly to Pilosocereus pachycladus. Also, the unknown plant has very few, fairly long hairs, while the Pilosocereus pachycladus has a whole headful of short shiny hairs at the areoles, which the flower buds erupt from. Again, any help sorting these plants out would be very greatly appreciated. Thanks, Carol

This is the one I'm 97% certain of ID.

Hi Carol,

I guess the second one isn't a P. pachycladus, but is it awfully hard to find a correct plant in columnar cacti... maybe have a look into Columnar Cacti:

I have no idea about the first one.

Cheers,

I also disagree with the ID and happen to have the same plant labeled as Lemairocereus chende.

This could be Escontria chiotilla, since it resembles the description and pictures of it. I'm assuming you purchased yours at a big box store, and the major wholesaler that supplies them also has E. chiotilla listed as a plant they grow in their plant library.
