 Rh constituente latiore; anticarum media lateralibus angustiore. Stamina tubo inclusa, supra medium unguium inserta; Filamenta quatuor, brevia; superiore sterili apice cum stigmato connato; reliqua antherifera: Antheræ laterales dimidiatæ; inferior didyma, lobis cum iis lateralium longitudinaliter connexis, ita ut lobus singulus inferioris cum respondenti laterali loculum unicum tandem bivalvem coustituit, nullo vestigio dissepimenti: Pollen triangulare. Squamæ hypogynæ nullæ. Ovarium turbinatum pubescens apiceque ornatum pilis brevibus crassis pellucidis strictis, monospermum: Stylus curvatus glabor sursum incrassatus deciduus: Stigma dilatatum obliquum, hinc apice filamenti arctissime connatum, inde desinens in cornua duo parallela distantia subulata. Nux crustacea obovata striata pilosa, apiceque coronata pappo brevi e pilis strictis crassioribus formato.

Obs. In my general observations on Proteaceæ I have noticed two very remarkable characters of Synaphea, namely, the cohesion of the barren filament with the stigma, which is peculiar to this genus, and the structure and connection of the antheræ, in which it agrees with Conospermum: it is also remarkable that these two nearly related genera should differ in the position of their barren and fertile stamina with relation to the perianthium; plants of the same natural family very generally agreeing in the order of abortion or suppression of these organs; to this, however, some other exceptions are known, and one has been already noticed as occurring in Drapetes.

The genus Synaphea seems to be confined to the south-west coast of New Holland, for it is more likely that Polypodium spinulosum of Burmannus (flor. ind. 233. t. 67. f. 1.) which I have formerly referred to this genus, as well as Adiantum truncatum of the same author, long since determined to be a species of Acacia, by Mr. Dryander, were brought from that coast to Batavia by one of the Dutch navigators, perhaps by Vlaming, than that they are really natives of Java, from which Burmannus received them.
