Growing in the Cerro Colorado. The flowers and fruit of this 
species are the same as those of P. grandiflora Walt., but the 
axillary infloresence gives it a very different appearance. 
Polygala setifera. Annual, branching from above the base, 
glabrous, 15 cm. high and less; leaves 8-12 mm. long, 2-5 mm. 
wide, alternate, obovate, apiculate or setiferous at the tip, attenu- 
ate to a short petiole or sessile base and decurrent on the stem as 
a wing I cm. or more; spikes terminating the branches, 1-2.5 
em. long, densely flowered, the conspicuous, setiferous bracts ex- 
ceeding the yellowish white flowers: wings broadly obovate, 2.5 
mm. long; sepals long-setiform, broadened at the base; keel

leaves, the solitary pistillate flower at the base: staminate flowers
