The above is Sir William Hooker’s description (con- 
densed) of a plant of this species introduced from Rio, 
which flowered in England. It differs in the following 
respects from our Jamaica plant. Calyx small, sub-trun- 
cated, 6-lobed. Petals 8, oblong, obtuse ; the 4 outer ones 
sepaloid ; the 4 inner yellow. Stigma pentifid, with the 
lobes obtuse, spreading and patulous. Berry ovate 
crowned with the calyx. — This comes nearer to Swartz’s 
description. 
I. Opuntia. 
Sepals many, adnate to the ovary, outer ones 
foliiform, inner pet aliform, with no tube beyond 
the ovary. Stamens oo . Style constricted at 
the base : stigmata several, thick. Berry ovate, 
umbilicated at the apex, tuberculated, frequently 
spinose. 
Name, that of a plant mentioned by Pliny. 
a. Prickles of different sorts ; the smaller ones 
setaceous, the larger ones longer and robust.
