158 New SPECIES OF SovTH AMERICAN PLANTS 
ceeding their pappus, very little expanded above, the short 
blunt Tcbes slightlv unequal, the short, blunt style-branches 
exserted, rough with short, thick hairs. 
Rays about 4, five mm. long, erect, purple, linear, sub-entire. 
“Local on dry banks and rocks below 1,000 feet, near Bonda, 
July to October. Has a strong mint-like odor." (Herbert 
H. Smith, Colombia, No. 528 pp.) 
Very near Lehmann's 933, but the disk-corollas of the latter 
are little more than half as long and of different shape, and 
much shorter than the pappus. Species near P. diffusa H. & A. 
Pectis densa. 
Glabrous, the stems diffusely pe the foliage densely 
matted, the inflorescence abundant. Branches slender, terete, 
i red-purple, the internodes about 1 cm. wap Leaves, 5 to I 
mm. long, 1 to 2 mm. wide, linear, the base broader and ‘clasping, 
the summit acute, the margin revolute, setose-serrate, the mid- 
rib very strong, the glands elongated, brown. Peduncles fili- 
form, about 2 cm. long, the heads 5 mm. long and half as broad, 
e involucre turbinate-cylindric, 3 mm. long, the scales 4, 
oblanceolate, acutish, the summit lightly ciliat». Rays about 
4, the purple corollas ks. slightly exceeding the disk, slender, 
E sub-en ire. isk-corol llas shorter than heir 
t oblon t 
hispid, the pappus of few strongly serrate pr dilated at the 
base, with short bristly chaff between, slightly exceeding the 
corollas. 
Species very near P. rosea, but the disk-corollas of different 
shape and shorter than the pappus, and the habit of the plant 
ang foliage very different. 
“Near Bonda, 250 feet, November 16. Local and rather 
rare in open lands. An infusion of the plant used as a febri- 
fuge.” (Herbert H. Smith, Colombia, No. 528, pp.) 
Whether Mr. Smith gave the same number to two species 
by error, or whether he believed them the same, I do not know.
