Gymnema. | LXXXV. ASCLEPIADEE (BROWN). 415 
axillary, twice shorter than the leaves, reddish-pubescent. Sepals very 
short, scarious at the margin, pubescent on the back. Corolla rotate, 
deeply 5-lobed, conical in bud, very shortly tomentose on both sides ; 
lobes ovate-lanceolate, acute. “Corona none. Style-hood 5-lobed ; 
lobes recurved ; stigma obtuse, projecting.”’ 
Mozamb. Dist. Portuguese East Africa: Lower Zambesi; near Tete, 
Peters. 
I have not seen this plant, but from the description T am sure that it is not a 
-Gymnema, but may perhaps belong to the genus Secamone. 
Gymnema nitidum, Benth. in Hook. Niger Fl. 456; Walp. Ann. iii. 61,— 
‘This plant is not an Asclepiad! Bentham must have examined a loose flower that 
did not belong to the plant, as his description, as well as his drawings on the type- 
sheet, indicate the floral structure of Gymnema. But the type specimen has one 
bud still attached; this I have soaked and examined withont removing it, and 
(although immature) I find its structure to be as follows : Sepals 5, short, thick and 
roundish. Petals 5, free, imbricate. Stamens 4. one being apparently somewhat 
impertect, incumbent on the sides of the ovary. Ovary superior, trigonous with a 
subsessile shortly 3-lobed stigma. .I could not dissect the bud further without 
destroying it. ‘The above characters and the general appearance of the plant refer it 
to Salacia ; I therefore propose for it the name of Salacia nitida, NV. £. Br. 
38. ANISOPUS, N. E. Br. in Kew Bulletin, 1895, 259. 
Calyx 5-partite. Corolla-tube short, campanulate ; lobes 5, spreading, 
very narrowly overlapping or almost valvate in bud. Corona double ; 
outer inserted at the mouth of the corolla-tube, consisting of 5 fleshy 
lobes at the sinuses (perhaps thickened sinus-angles of the corolla?) or 
of a membranous ring ; inner of 5 fleshy lobes arising from the staminal- 
column, adnate to it in their lower part, free above, opposite the 
anthers. Staminal-column arising from the base of the corolla-tube ; 
anthers erect with membranous appendages. Pollen-masses_ erect, 
solitary in each anther-cell, attached in pairs by short caudicles to the 
pollen-carriers. Follicles very long, widely divergent, terete, acute, 
smooth, seeds crowned with a tuft of hairs.—A tall glabrous twiner. 
Leaves opposite, petiolate, herbaceous, with distinct veins. Flowers in 
umbels, axillary and from both axils, one umbel pedunculate, the other 
sessile and developing later. 
Species 2, endemic. 
Since the publication of this genus I have seen flowers preserved in fluid, in 
which the processes I have described as outer coronal-lobes appear to be raised or 
tubercular projections of the sinuses of the corolla it-elf rather than true coronal 
processes. ‘The name is formed from avicos, unequal and zrovs, a foot, in allusion to 
one umbel of each pair being stalked and the other sessile. The coronul-lobes or 
tubercles at the mouth of the corolla resemble those of Leptadenia, and those on the 
staminal-column those of Marsdenia, near which genus [ place it for the present. 
Leaves rounded at the base ; outer corona of 5 minute 
lobes. = 
Leaves acute at the base; out2r corona of a mem- 
branous ring. . . : : . : . 2. A, bicoronata.
