to the stem. Leaves (2 inches broad) cordato-subrotund, irregularly 

 angled, and deeply and unequally serrato-dentate, strongly 5-7 nerved, 

 reticulate, somewhat wrinkled, rigid, concave, pubescent on both sides, 

 lessening upwards into the form of hractece, which, at the apices of the 

 stem and branches, are linear-lanceolate, entire, and subsessile, nerves 

 prominent above, but more so below, with small aculei on both sides, 

 projecting forwards. Petioles (3^ inches long) longer than the leaves, di- 

 varicated and curved forwards, rigid, aculeated, obscurely channelled 

 above, containing pith. Flowers collected near the apices of the stem and 

 branches, rising singly on short, robust, erect, hairy peduncles from the 

 axils of the diminished leaves or bracteae. Involucre 10 parted, segments 

 subulate, somewhat spreading, rigid, covered with long simjile harsh co- 

 lourless hairs, which arise from large greenish glands. Calyx longer than 

 the involucre, similar to it in texture and colour, S-cleft, segments broad, 

 acute, and each composed of three coarse conniveut ribs, similar to the 

 segments of the involucre, translucent at the glands, united by a green 

 membrane. Corolla (24 inches across when ex[)anded) 3-4 times the 

 length of the calyx, campanulate, revolute in its edges, many-nerved, 

 sulphur coloured, with a deep and beautiful crimson heart ; segments 

 (14 inch long, 1^ broad) very sparingly pubescent, the crimson part ha- 

 ving a considerable number of short erect glandular hairs, obovato-cu- 

 neate, thickened at the base, forming a short fleshy tube, along which 

 their edges are decurrent. Stamens numerous, erect, as long as the dark 

 centre of the corolla, arising from its tube of deep crimson, with gL iidular 

 pubescence : anthers on short partial filaments, sometimes united in 

 pairs, arising from the sides of the common sheath, kidney-shaped, burst- 

 ing at a groove along the back, dotted, in the bud forming a dense orange 

 coloured capitulum; pollen granules spherical, so large that they may be 

 seen through the anther-case, and, when exposed and examined under 

 the microscope, are found to be pubescent. Style scarcely longer than 

 the stamen-sheath, purple, and slightly pubescent in its ujjper part. 

 Stigmas 5, capitate, jjurple, angular, fringed. Capsules five, cohering 

 into a cone, hard, hairy. Seeds angular, erect, several in each caj)sule, 

 embryo central, bent, radicle straight, plume plicate. 

 This very handsome species, which was raised in spring 1829 at the Royal 

 Botanic Garden, from seeds received from New Holland by Mr Goodsir, 

 flowered in the stove last year, and again this season. We were not in- 

 Ibrmed in what district of New Holland it was collected ; but I learn 

 from Sir Lambert, that a species which, from Ills account, 1 take to be 

 the same, has flowered with him, having been obtained from Morton 

 Bay.

Description Stem round, rooting at the base, flexuose, branched, dense- 

 ly covered with innumerable short harsh hairs, which seem rough under 

 the microscope, and are scarcely stinging : higher up there are a few 

 deep green oblong spots on the stem, and the hairs are mixed with others 

 which are twice or thrice as long, smooth, dark brown, arising from larger 

 glandular bases, and are stinging; these increase in number upwards, and 

 are much crowded near the top. Leaves (5 inches long, 34 broad,) scattered, 

 ])etioled, oblong, pinnatifid and incised, or oftener bipinnatifid, or almost 

 pinnated, and the pinnae pinnatifid, pubescent on both sides, but espe- 

 cially the under, which is paler, with prominent branching veins, which
