OPUNTIA.

Gartenb. 6: 434. 1830) — which was later taken up as Consolea leucacantha by Lemaire (Rev. 

 Hort. 1862: 174. 1862), seems to belong here rather than to 0. spinosissima. If it came 

 from Mexico, as reported, it could not be 0. spinosissima or any of its relatives, for none 

 of them is known from Mexico. 



Opuntia siihferox Schott (Pfeiffer, Enum. Cact. 167. 1837) was given as a synonym 

 of 'this species, while 0. leucacantha laevior Salm-Dyck (Cact. Hort. Dyck. 1844. 47. 1845) 

 and 0. leucacantha subferox Salm-Dyck (Forster, Handb. Cact. 497. 1846) were supposed 

 to be based on 0. subferox. 



Opuntia leucantha (De Candolle, Prodr. 3: 474. 1828), unpublished, is doubtless the 

 same as 0. leucacantha. 



Fig. 214. — Opuntia leucotricha 



Opuntia fulvispina laevior Salm-Dyck (Pfeiffer, Enum. Cact. 164. 1837) and 0. ful- 

 vispina badia Salm-Dyck (Cact. Hort. Dyck. 1849. 65. 1850) are given as synonyms of 

 O. leucotricha; while 0. riifescens Salm-Dyck (Forster, Handb. Cact. 493. 1846) is given 

 as a synonym of fulvispina laevior; all these seem to belong here. 



This is called durasnilla in Mexico. It is grown in Bermuda under the name of Aaron's 

 Beard.
