16. Wedelia, Jacq. 
Hirsute or scabrid-pubescent herbs or undershrubs, sometimes 
scandent. Leaves opposite. Heads axillary or terminal, hetero- 
gamous, rayed. Bay-florets 2 , fertile, ligulate, spreading, entire, 
or 2-toothed at the apex. Disk-florets £ , fertile or the inner sterile ; 
the corolla tubular, regular, with elongate 5-toothed limb. Involucre 
campanulate or sub-hemispheric ; its bracts sub-2-seriate, the outer 
3 to 5 usually herbaceous, the inner dry; receptacle flat or convex, 
the pales enclosing the flowers. Anthers entire or sub-sagittate at 
the base. Style of £ florets with acute arms hirsute at their 
tips. Cypsclas cuneate-oblong or obovoid, thick, smooth or tubercled, 
laterally compressed or the outer triquetrous, tip rounded, margins 
obtuse or thickened ; pappus none, or reduced to a toothed cup or ring, 
or sometimes of short scales with occasionally a few bristles. — Distbib. 
Species about 70, tropical and sub-tropical. 
Wedelia biflora, DC. in Wight Contrib. PI. Ind. 18. Scandent; 
stem and branches hispid-puberulous when very young, afterwards 
almost glabrous, obtusely 4-angled, grooved when dry. Leaves mem- 
branous, broadly ovate or ovate-subrhomboid to lanceolate, apex 
acuminate, edges coarsely serrate except at the broad, slightly 
euneate base; both surfaces dull olivaceous green when dry, 
minutely reticulate, sparsely hispid-puberulous ; main-nerves one- 
large pair ascending from the base of the midrib to near the apex 
branching outwards and one or two smaller pairs from above the 
middle of the midrib, all distinct on both surfaces ; length 2 to 4'5 in. ; 
breadth l - 25 to 2 - 75 in.; petioles '75 to 1'5 in., those of the branches 
smaller. Heads about '5 in. in diam., solitary on a short peduncle 
•75 in. or less in length, or 2 to 4 on peduncles two or three times as 
long. Involucral bracts in two rows, oblong or ovate-lanceolate, 
apiculate, concave, scabrid-puberulous outside like the peduncles, 
often recurved. Bipe cypselas triquetrous, scaberulous, the apex 
with some hairs and several short bristles, one longer than the 
others. Hook. fil. PL Br. Ind. III. 306. W. scandens, Benth. ; Prain
