 than.Op. vulgaris^ and even Op. missouriensis, Is that now the species-,. 

 which you want to name Op. Rafinesquli ??0f the seedlings plants, which 

 I have (seeds received from you))is one Opuntia of 5th fe (? r E.D. ) f , 

 which coincides entireTy with prostrata: the home Tand would be verjy

 to have seen in the botanical garden in Madrid the Op, vulgaris under 

 the name Op.cochinellif era (and actually covered with Cochinelle) - 

 In my subdivision of the Opuntia the se species would have to be trans- 

 ferred next to Op, serlcea in the | Pulvinatae, . Of Op.missouri ensls 

 I have the var. elongata ( Op. media Haw - Op.splendens Hort) \ which you 

 consider perhaps as 0. frag ilis».
