Flowering plants not exceeding at most 8 or 10 inches in length. The stems 
rise erect, and soon become branched, the branches drooping. Whole 
plant composed of compressed, somewhat foliaceous, oblong joints, plane 
above, with a slight groove or channel, somewhat keeled beneath, the 
margins having distant serratures, which are often red, especially in the 
young" joints, and there also furnished with small fascicles of hairs; the 
extremity truncated, with 2 rather long teeth at the angles. 
Flower arising from the truncated extremities of the joints, 3 inches long, of 
a beautifully deep rose colour, standing out. horizontally, formed of many 
imbricating petals: or the 4 or 5 lowermost of these may be considered 
a calyx, since they stand a little remote from the others; the ‘rest are 
united by their bases into a long whitish tube, the limb of 8 or 9 seg- 
ments, large, spreading, oblique, ovate. Stamens numerous, much longer 
than the tube of the corolla, in 2 rows, the outermost arising from the 
base of the corolla, the inner, from the receptacle, and forming a tube 
around the style, (see f. 2.) Filaments slender, filiform ; Anthers oblong, 
2-celled, yellow, as well as the pollen. Pistil: —Germen obconical, small, 
inferior, greenish, tipped with rose-colour, smooth. Style filiform, red, 
as long as the stamens, a little curved downwards. Stigma clavate, form- 
ed of 6 connivent segménts. 
This beautiful species, to the brilliant colour of whose blos- 
scms no pencil can do justice, flowered in our Botanic Garden
