ON THE PROTEACEiE OF JUgSIEU. 187 



there sufficient materials from which they may be charac- 

 terized as distinct species. 



NlVENIA. 



Protea concava. Lam. Illust. Gen. \, p. 234, n. 1217. 

 Poiret, Enoyc. Botan. o,p. 642. 



A species of Nivenia, and perhaps one of those described. 



NiVENIA ? 



Protea candicans. Thunb. Prod. Append. 186. 



Probably a Nivenia, and perhaps not different from N. 

 moUissima: it may however be a species of Serruria, in 

 which case it is probably S. candicans. 



Fno-TEA prostrafa. Thunb. Prod. 27. 



I know not to what genus this may belong ; but from 

 the species near which Thunberg has placed it, it may be 

 supposed to be either a Protea or a Leucadendron : if the 

 latter, it is probably not very different from L. retusum. 



Hakea. 



Conchium drupaceum. Gart. Carp. 23, jo. 217, t. 219. 

 T cannot refer this fruit to any of the species I have de- 

 scribed. 



Embothrium chaparro. Humb. ^quin. Pot. 



Of this I know nothing but the name, which occurs in 

 Humboldt's Chart of Equinoctial Botany, and is placed 

 there at the height of about 1600 feet. 



Embothrium strobili7ium. Labill. Nov. Holl. 2, r^a 

 p. 116, t. 265. 



The seeds of this remarkable plant, which I am acquainted 

 with only from Labillardiere's figure and description, being 

 unknown, and the internal structure of its ovarium not 

 having been examined, its genus cannot be determined. 

 Its regular and deeply divided calyx, the four glands at the 

 base of the ovarium, and its vertical equilateral stigma, 

 point out its near affinity to Knightia, from which it differs
