ON SOUTH-AMERICAN APOCYNACE;E. 39 
leaves towards the extremity are 24 in. in length, and 1 in. in breadth. The raceme, simply 
spicated, rises in the dichotomy of the branches; the peduncle is 4-2 in. long, very 
closely marked by the cicatrices of the abortive flowers, seldom leaving more than 
2 flowers at the apex, on slender pedicels 6-8 lines long; the ovate sepals are 1 line long ; 
the tube of the corolla is 5 lines long, narrowly cylindrical above, ventricose below the 
middle; the segments are insequilateral and oblong, 3 lines long, 2 lines broad, of a 
reddish colour, simply convoluted sinistrorsely in sestivation. The stamens are seated in 
the swollen part of the tube; the filaments arise out of 5 pilose lines, a little above 
the base of the tube; the anthers, twice the length of the filaments, are 2-lobed 
at their base, acuminated by a lanceolated membrane. No disk. Ovaries 2, pointed 
oblong.

In Guiana: v. s. in hb. meo (n. 9241) Guiana (Schomb. 8). 
A species well distinguished from the former by its more slender branchlets, not 
thickened at the nodes, by its smaller, more lanceolate, very membranaceous leaves, 
almost sessile; branchlets striolated, dichotomous; leaves narrowly oblong, gradually 
cuneate and insequilateral at the base, with a long narrow acute acumen, very slender 
arcuately ascending nerves, very unequal at each node, 34-24 in. long, 1— in. broad, on 
petioles scarcely more than 4 line long, or sessile. The peduncle, as in the preceding, 
is seated in the dichotomy, ¿-1 in. long, densely crowded with cicatrices, rarely more 
than 3- or 4-flowered at the summit, on pedicels 6-8 lines long; sepals 1 line long; tube 
of corolla equally cylindrical, a little swollen above its base, very slender, 5 lines long, 
segments unequally linear, 2 lines long, 3 line broad, of a pale yellow or whitish colour, 
convoluted sinistrorsely in «estivation; stamens as in the preceding species, enclosed in 
the swollen inferior portion of the tube; no disk; 2 conical oblong ovaries.

5—6 lines long; the upper pairs of leaves half that size; axillary panicles on slender
