I find about ten or twelve species of this genus in the Hookerian Herbarium, of which I suspect some are very 
variable in habit ; the majority are natives of the South-western quarter of the continent, and the remainder of the 
South-eastern and Tasmania.— R. pinifolim, the only Tasmanian species, is a small, erect, branching, glabrous 
shrub, 2-4 feet high, with numerous alternate leaves, which are about an inch long, suberect, very narrow-linear, 
acuminate, their margins revolute almost to the midrib. Mowers monoecious, erect, about $-£ inch long, on long, 
strict pedicels, bracteolate at the base, towards the ends of the branchlets, the female uppermost, with shorter pedun- 
cles ; males generally axillary, and with the peduncle longer than the leaf, often imperfectly jointed about the middle. 
Calyx ohconic, irregularly four- or five-lobed; lobes blunt, minutely ciliated. Corolla of five imbricate white 
petals, twice to four times as long as the calyx. Male flower with a long cone of stamens united by their filaments, 
the anthers extrorse. Female a three-celled ovary, subtended by five hypogynous scales, and having three linear 
bipartite stigmas. Capsule | inch long, densely covered with soft waving spines, woody, three-celled, of three 
woodv cocci, that separate from a persistent central column, and dehisce down the ventral suture; epicarp coria- 
ceous, easily separating from the crustaceous woody endocarp. Seed narrow-oblong, with a smooth, shining, polished, 
mottled testa, and prominent caruncula at the top. (Name from the similarity of the fruit and seed to that of the 
Castor Oil, Ricinns Pohm-dmtu)

I have followed Endlicher (Gen. Plant. Suppl. iv. 90) in adopting the name of Beyeria for this genus, instead 
of CohjpbrMigma, Klotzsch, which appeared about the same time ('Plantas Preissianse,' i. 175). I have seen about 
fifteen species of the genus, the majority of which are natives of South-western Australia. All are shrubby, with
