fouquieria or not?

[TexasColdHardyPalms]

I saw these earlier today and they cpuldnt tell me exactly what they were. They appear to be a fouquieria or relative. Can anyone id them?

[JubaeaMan138]

Alluaudia procera ? Maybe? madagascaran ocotillo 

[TexasColdHardyPalms]

Could they be Didierea?

[JubaeaMan138]

Doesn’t Didierea normally have longer thorns ?

[JubaeaMan138]

Did you acquire these ? If you did the flower would tell us what it is easily don’t you think?

Don't think it is either Didierea or Alluaudia (leaf arrangement along stems doesn't look quite right) ..or a Fouq. sp (Spine arrangement along stems different, or so appears in the pictures). There is, what looks like a Fouq. splendens to the far right in the picture though... 

   Euphorbia  also crossed my mind but... maybe, if it bleeds latex sap..  There appears to be a larger specimen, on the right ( picture #1) that might have / had flowers? on it.. Might give it another look and get some close up pictures if possible..  Interesting...

There weren't any flowers as I searched all over for flowers as a clue.  There were a dozen of the bigger spined species and only a handful of the tightly spinned species.  The tightly spinned species branched more and stayed more decumbent. That is a F. Spendens on the right.  These are in full, hot sun if that makes a difference.  Zero shade on these.

I decided not to buy either one.

Not a positive id, but after some searching, Euphorbia didiereoides seemed to come close to those in the pictures, based on spine / apparent leaf arrangement along the stems..
