ON THE PROTEACE.E OF JUSSIEU. 187
there sufficient materials from which they may be charac- terized as distinct species.
NlVENIA.
Protea concava. Lam. Illust. Gen. 1, p. 234, n. 1217. Poiret, Encyc. Botan. o,p. 642.
A species of Nivenia, and perhaps one of those described.
NlVENlA ?
Protea candicans. Thumb. Prod. Append. 186.
Probably a Nivenia, and perhaps not different from N. mollissima : it may however be a species of Serruria, in which case it is probably S. candicans.
Protea prostrata. Thunb. Prod. 27.
I know not to what genns 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.
Concilium drupaceum. Gcert. Carp. 23, p. 217, t. 219. I cannot refer this fruit to any of the species I have de- scribed.
Embothrium chaparro. Humb. JEquin. 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 strobilinum. Labill. Nov. Roll. 2, r222 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
