-- often fasciculated, on short branches, patent or reflexed, very rigid, lanceolate, glabrous, below only furnished with several rather long, rigid, dark-coloured hairs, deeply pin- natifid, the segments patent, triangular, acute and mucro- nate, dark green above, paler beneath, marked with nume- rous reticulated, slightly elevated veins, which are glabrous, while the small areolæ are white as if mealy. Involucre terminal, solitary, of numerous imbricated, linear scales, clothed with short, dark brown hairs, surrounded by a sort of ray of numerous leaves.

In the inestimable Prodromus Fl. Novæ Hollandiæ of Mr., thirteen species of are enumerated, and in the Supplement to the same work, twelve new spe- cies are added; all of them, as Mr. observes, natives of the South-western shores. "It is worthy of remark" says that gentleman, "that while is generally spread over all the coasts of New Holland and of Van Diemen's Island,  has hitherto been observed only on that part of the South coast called Lewin's Land where, however, its species are nearly as numerous and abundant as those of  itself." D. armata was dis- covered by that gentleman in the country just mentioned, and from seeds sent from thence by the late Mr. , plants have been raised in the Glasgow Botanic Garden, which flowered in February, 1833.
