"Trunk erect. Bark dark and cracked. Branches, at first, erect, ultimately spreading, covered with soft, yel- lowish pubescence when young. Buds in whorls, but gene- rally all, excepting one or two, abortive. Leaves petiolated, subverticillated or scattered, ligulate, dry, stiff, undulated,

-- green and naked above, below, covered with white tomen- tum, through which many small reticulated veins appear; when young covered with yellow tomentum on both sides, sinuato-serrated, occasionally entire, serratures mucronate, middle-rib prominent behind. Flowers terminal, head two to three inches long, less than half the length of the leaves, which are generally crowded at the base. Calyx silky.

We have a plant which has not yet flowered, but which I can consider only a variety, that is more vigorous in its growth; the trunk swollen into joints; the branches more erect; the leaves more decidedly verticilled; more of them entire, and many of them lanceolate, having evident nearly transverse primary veins, the pubescence on the young shoots being red-brown." Graham.

Introduced to our gardens, from the neigbourhood of Port Jackson, in 1788, by Mr. : but, according to Hortus Kewensis, it does not appear to have flowered when the second edition of that work was pub- lished. Our drawing was made from a a fine plant which flowered at the Edinburgh Botanic Garden, in May, 1827. The seeds had been sent to Dr. Graham, in 1819, by Mr. . Both from Dr. and Mr. obser- vations on the species, it seems to be liable to much varia- tion: the latter gentleman indeed observes. "Species poly- morpha, cui nimis affines sunt B. insularis et compar."
