POLYGALACEAE, 
Potyeata Nana, Ma., Y.—The flowers grow in close 
spikes. The early ones are sessile and their flowers ap- 
pear to be habitually self-fertilized. The later spikes are 
borne on stems two or three inches high. The flowers are 
pale yellow, the tip of the keel more orange-yellow. 
The keel bears a crest of 8 slender lobes. Pollen is de- 
posited on a terminal tuft on the style. The stigma is 
lateral. Nothing seems to prevent pollen from the 
stamens being carried down to the stigma, though in- 
Sects will no doubt effect cross-pollination. A probos- 
cis 4 mm. long can easily exhaust the nectar. Ja. 26- 
Ap. 24, 1 visitor observed, Mr. 2.

ginosa 3.
