rate, hispidulous. Heads terminal or lateral, sessile or peduncled.

Stemmodontia torachycarpa (Baker), Morong. 

 Wedelia hrachycarpa Baker in Mart, Fl. Bras., vi, pt. 3, 181. 



Asuncion (52 and 819). October. = Balansa 855. 



A rough hairy, branching plant 6-9 dm. high, with good sized, 

 solitary heads on peduncles longer than the leaves. My specimens 

 differ from the type in having petioles 1-8 mm. long. Leaves ovate 

 or lanceolate, opposite, 3-nerved, serrate, 2-J-5 cm. long. Rays 8, 

 yellow. Pappus horny, cupulate. Achenia densely papillose. 

 Abundant in the neighborhood of Asuncion, both in low grounds 

 and uplands. 



We are using the name Stemmodontia, Cass., for this genus, be- 

 cause Wedelia, Jacq.(l760), is a homonym of Wedelia, Loefl. (1758), 

 as pointed out by 0. Kuntze.

The Aspilias are hirsute plants, with large, solitary, yellow- 

 flowered heads on long peduncles, reminding one in general of 

 many of our smaller Helianthi. No. 1520 has showy flowers 2^ 

 cm. high, 4 cm. in diameter when expanded ; rays 9-12 ; pappus of 

 2 scales. Stems 4-5 dm. high, branching, decumbent. Leaves 

 sessile, serrate, hispidulous, 5-10 cm. long. No. 464 is smaller, 

 only 3 dm. high, with a softer pubescence. Its leaves are entire 

 or remotely serrulate, linear-lanceolate, sessile, somewhat obscurely 

 3-nerved, the largest 10-12 cm. long and 1^-2 cm. wide. Rays 10, 

 golden-yellow, 2-toothed, about 2 cm. long. No. 216 has heads 

 much smaller than in the preceding species, being only 1^ cm. high, 

 and 2^ cm. when expanded. Leaves ovate-lanceolate, petioled, 

 3-nerved, serrate, the blades 6-10 cm. long, l^-S^ cm. wide. Pappus 

 of 1 or 2 long projecting bristles. Achenia 5 mm. long, flattish, 

 4-angled, hairy, narrowing to the base, with a smooth, shining, 

 callous base, somewhat pitted or ridged on the faces. Whole plant 

 very rough, growing to a height of 9 dm.
