teeth at either side of the otherwise rounded summit. Disk- 
flowers 6 mm. long, the black akene about a fourth of the total 
length, obovate, compressed, without pappus. Corolla 5- 
toothed, the teeth ovate, acutish. Anther-cells acute at the 
base. Style-branches elongated, recurved, acuminate. 
"Open ground, in dry water-courses, near the coast at 
Playa Brava, April 1. Form of leaf constant in a long series of 
specimens." (Herbert H. Smith, Colombia, No. 516.) 
Wedelia heterophylla. 
Strongly strigose and very scabrous, the branchlets stout, 
costate, very leafy, the internodes 5 to 7 cm. long. Petioles 
3 cm. long, broad, margined, channelled and costate. 
Blades 7 to 14 cm. long, 3 to 8 cm. broad, ovate, the very abruptly 
acuminate rounded base tapering into the petiole, long-acumin- 
dark-green, slenderly 3-nerved, the venation inconspicuous. 
Outer involucre little exceeding the disk, ef about 5 scales which 
summit, strongly 3-nerved. Disk about 1 cm: long and a hal 
broader. Rays about twice the length of the outer involucre. 
Disk-flowers about the length of their acutish scales, the ovary 
half the length of the corolla, the pappus saucer-shaped, with 
strongly lacerate margin. ne 4 mm. long, the fimbriate 
margin of its pappus erect, its margins strongly cartilaginous- 
thickened, its sides sharply keeled. 
Species very near the next and possibly a variety of it, but 
the almost hispid leaf surfaces, the smaller heads with short, 
broad outer scales, and inner scales without the purplish acumi- 
nation, indicate that it is distinct. Smith sends several col- 
lections under the same number, which differ considerably. 
One “from Bonda, July, is a shrub, 4 to 6 feet high," has the 
leaves only about half the size described above, another has 
them elongated-lanceolate. Of this Smith says “An erect 
shrub, 2 feet high, collected near Cacagualito, 1600 feet, Nov- 
ember I5." 
“Varies greatly in the form and pubescence of the leaves, 
size of flowers and habit. It may be a low compact shrub or 
sub-scandent to 6 or 7 feet. The rough stem and stiff curved 
hairs on the veins seem characteristic. Generally there are
