(perhaps more) in diameter. Stems 2-4 inches high, somewhat fleshy, 
shrinking in drying (the figure, taken from a dried specimen, is pro- 
bably too slender), several times forked, the ends of the branches stand- 
ing nearly on a level. Leaves opposite (young, half-grown leaves only 
yet seen), 1-2 inches long, $ inch wide, subsessile, flat, smooth, and 
thickish in substance, penninerved, the veins obvious, but not prominent. 
Peduneles in the forks of the branches, or opposite a solitary branch, the 
leaves generally abortive and reduced to mere scales on the flowering 
branches. Cymes generally 3-flowered, the pedicels and peduncles each 
4 inch long. Calyx small, its lobes ovato-lanceolate or lanceolate, 
acute. Corolla ‘‘a rich purple,’’ 5-7 lines in diameter, rotate; the 
segments elliptic-oblong, obtuse. Corona exserted, the scales cuneato- 
spathulate, with a much acuminate, triangular point. Anthers not half 
as long as the squame, ovate, with a minute triangular dilatation at the 
extremity. Pollen grains quaternate, aggregated on the flattened, spoon- 
shaped extremity of the stigmatic-gland. ol/icles unknown. 
This appears to be quite distinct from any of the several species of 
Raphionacme, and is the most glabrous of any with which we are yet 
acquainted, The genus ranks among the small group of Periplocee, 
which connects the true Asclepiadee with the Apocynea. Here the 
stamens stand apart on the tube of the corolla, as in Apocynee, but the 
stigmatic glands of the pollen are a modified form of those of ordinary 
Asclepiadee.
