the throat, seated on 5 pilose lines; disk of 5 oblong free lobes, half as long as the 2 
pilose obtusely oblong ovaries; style slender, bearing a clavuncle membranaceous at its 
base, adhering to the anthers; 2 short, erect, terminal stigmata; 2 divaricate follicles, 
terete or subfusiform, 3 in. long, 24 lines thick, arcuate; seeds without an apical coma, 
oblong, subcompressed, with a central hilum on one face, densely covered all over 
with erect cottony hairs, which extend far beyond the apex; embryo in thin albumen, 
with 2 linear-oblong flat cotyledons 8 times as long as the narrow terete superior 
radicle. 
A drawing of this species, with its floral analysis, is shown in Plate XII. B.

The opposite leaves are fixed on the edges of the prominent transverse compressed 
nodes, which are ¿ in. apart; the leaves are 3-4 in. long, 14-14 in. broad, on petioles 
3-4 lines long, and are conspicuous for the concave glands seen beneath in the axil of 
each nerve. The fructiferous peduncle is 9 lines long, terminated by 2 suberect, terete, 
tapering follicles 22 in. long, 23 lines broad, containing numerous cottony seeds densely 
covered by long, soft, ascending hairs, which extend 6 lines beyond the summit, being 
very short towards the base; the testa is 9 lines long, 13 line broad, very compressed ; the 
raphe and hilum are seen on the middle of one face. 
A drawing of this species, with its follicles, and analysis of its seeds, are seen in 
Plate XII. c.

This species cannot belong to any other genus than Robbia, with which it agrees well 
in all its essential characters. It is glabrous, with an erect, branching, woody stem, the 
branches being virgate; the leaves are ternately verticillate, elliptic-oblong, very obtuse, 
coriaceous, below finely reticulated, marked by many close impressed dots, on longish 
petioles; flowers aggregated in a cyme. As in the preceding species, one of its follicles is 
abortive, the other being very elongated and narrow, more than 18 in. long, 2 lines 
broad, containing many oblong-linear compressed seeds covered all over with very long 
white hairs.
