20. V. Buchtieni n. sp. 
Stems suffruticose, erect, sparingly branched, 3-4 dm. high, softly 
pubescent above, becoming thinly pubescent or glabrate with age; leaves 
rather crowded, the blades linear-oblong, broadest near the middle, 5-6 cm. 
long, 6-11 mm. wide, acute, entire, gradually acuminate or cuneate to the 
base, sessile or on petioles 2-3 mm. long, thinly pubescent with papillose 
hairs or becoming glabrate above, comose beneath with brownish hairs on 
the midvein and margin and sparingly hirsute on the surface, the midvein 
prominent beneath, the lateral veins faint, sharply ascending and irregular; 
cymes 2-4, terminal and subterminaff scarcely branched, as much as 8 cm. 
long, bearing 2-6 heads; bracts resembling the leaves but smaller, the lower 
25 mm. long, the upper gradually reduced to 10 mm. long; heads sessile, 
about 21-flowered; involucre campanulate, 7 mm. high, dull purple; scales 
appressed below, loosely erect or somewhat spreading above, narrowly 
lanceolate, long-acuminate, nearly glabrous; achenes thinly hirsute, 3 mm. 
long; pappus dull brown, the bristles 6 mm. long, the outer scales broadly 
linear, 0.9-1.1 mm. long. 
Type: Buchtien 1328, collected near Mapiri, at an altitude of 700 
meters, and deposited in the herbarium of the New York Botanical Garden. 
V. Buchtieni is closely related to V. deflexa Rusby, from which it differs 
in the characteristic pubescence of the leaves and the color of the involucre.
