C. glabra, icosandra ; foliis petiolatis stipulatis adultis bracteisque glabris. Brown MSS.

The generic character now offered is from the pen of Mr. Brown, and has been framed with the accustomed skill and foresight of that learned naturalist with a view to the cluster of confining genera from the same regions, which will be found near it in the concluding volume of his ' Pro- dromusof the Flora of New Holland/ Achenium implying an indehiscent originally one-seeded seed-vessel, while that of the present genus, though eventually one-seeded, having been found by Mr. Brown to originate in a germen with two ovula, one of which proves constantly abortive, he has thought it advisable to suggest Achenopsis as a more precise denomination for this sort of seed-vessel.

Glabra is the first of the genus that has presented itself in our European gardens, and is native within the colony of Port Jackson, where it was found by Mr. Brown, whose herbarium contains likewise four more of its congeners, of which that gentleman has favoured us with the following account •. — Three, our plant being one, were observed by him in the colony above mentioned, as well as in Van Diemen's Island, and agree in having a petioled stipuled foliage and icosandrous flowers ; a fourth he discovered on the south-west coast of New Holland, this had likewise a petioled stipuled foliage, but the flowers were decandrous ; the fifth he observed on the north coast of the same conti- nent (in the Bay of Carpentaria), in that the flowers were icosandrous as in the three first-mentioned species, but it differed from all the others in having a foliage without cither petioles or stipules. Through these modifications the* genus will be found to unite with its confining co-ordi- nates at different points. Bot. Reg. 393 (1819).
