New Species of South American Plants 157 



long, 2-4 cm. wide, ovate, rounded to cordate at the base, 

 acutish at the summit, coarsely serrate with short and broad 

 teeth and narrow acute sinuses, the reticulate venation slender 

 and lightly prominent beneath, ont or two principal pairs of 

 veins starting from near the base and strongly ascending; thin, 

 soft-hairy beneath and scabrous above. Heads umbellate at 

 the ends of the branchlets, solitary on slender peduncles which 

 are i to 1.5 cm. long, the heads about 5 mm. long, sub-cylindri- 

 cal when young, at length campanulate and nearly as broad as 

 long. Involucre narrowly campanulate, about two-thirds as 

 long as the disk. Outer scales green and rough-hairy, appressed, 

 ovate and obtuse, the inner light-brown, sub-glabrous, nerved 

 and obtuse. Rays absent. Disk-akenes 2 mm. long, narrowly 

 turbinate, minutely hispid. Corolla-tube 2 mm. long, the lobes 

 more than i mm. long, spreading or recurved, their pappus 

 extending a little above the base of the lobes. Pappus- scales 

 distinct, regularly attenuate from a broad base to a very fine 

 point, strongly serrate or lacerate above. Scales of the recep- 

 tacle nearly equalling the pappus, broadly obovate, finely nerved, 

 the summit nearly truncate, strongly 3-toothed, the teeth sub- 

 ulate and attenuate and about a fourth of the entire length of 

 the scale. Anther-bases obtuse. Style-branches long-exserted. 

 strongly recurved. 



" Common on campo-land below 3,000 feet. Collected 5 miles 

 east of Bonda, September to October." (Herbert H. Smith, 

 Colombia, No. 524.) The same as Helton's 353 from Colom- 

 bia. 



Species near C. Moritzii, but the pappus more slender and 



the leaves different. 



Pectis rosea. 



Glabrous; apparently perennial, the stems diffusely branch- 

 ed, the branches ascending, reaching 2.5 dm. m length, at hrst 

 very slender, becoming rather stout and very leafy, sharply 

 angled, the internodes mostly about i to 1.5 cm. long. Leaves 

 simple, thick, spreading and lightly recurved, 12 to 25 mm. 

 long, I to 3 mm wide in the dried condition, with the niargms 

 revo ute, linear, attached by a broadened base, obtusish, having 

 a strong midrib, sharply prominent -^"derne^th the vena ion
