Descriptive Notes on Papuan Plants,

Spermacoce Papuana. 
Leaves linear, acute, as well as the stems almost glabrous ; stipules 
divided into a few setaceous segments; flowers in the axillary and 
terminal somewhat verticillar clusters rather numerous ; lobes of the 
calyx four, linear-setaceous, longer than the tube ; loies of the corolla 
exceeded three or four times by the length of the tube, semilanceolar, 
not auriculate ; faux unbearded ; stamens hardly longer than the limb 
of the corolla; both valves of the capsule separating from the mem- 
branous septum. 
On the Baxter-River ; Rev. S. Macfarlane. 
Root not obtained. Leaves 1-2 inches long and as many lines broad, 
slightly revolute, but not much thickened at the margin. Stipular setae 
about 2 lines long ; nearly of their size and form also the lobes of the 
calyx. Tube of the corolla about of 3 lines length, gradually narrowed 
downwards ; the lobes outside beset with minute hair. Filaments adnate 
up to the summit of the tube ; the free part not much longer than the 
narrow anthers. Style smooth, 3-4 lines long. Valves of the capsule 
about lines long. Seeds narrow-oblong, black. 
This species stands in near relationship to S. leevigata (F. M. Fragm. 
Phytogr. Austr. iv. 41) ; the leaves are however not strongly nerved 
nor mucronulate, the stipular setse are shorter, the flowers mostly 
axillary, the limb of the corolla rather shorter in proportion to the 
tube. The examination of ampler material may reveal hereafter further 
differences. A plant very similar to the Papuan species was obtained 
by Mr. Dmmel at Cape York, but its stipules are generally undivided 
and the corolla is shorter and outside glabrous,

Baxter’s River; Rev. S. Macfarlane. 
Wedelia biflora, Cand. in Wight’s Contribut. p. 18, was gathered at 
Geelvink’s Bay by Dr. Meyer. 
Adenostemma viscosum, R. et G. Forst. Charact. Gen. t. 45, was found 
at the same place by Mr. Teysmann according to Dr. Scheffer. 
Emilia purpurea, Cassini Diction, xxxiv. 393, was noted by Lesson at 
Port Doreh.
