ple, like the stamens and stigmas. This color is the only 
entomophilous character the plant shows. The stigmas are 
very large and have their edges thrown into convolutions. 
This great development seems to insure contact with the 
large anthers which surround them. On one occasion I found 
a number of beetles, Cenxtrinites strigicollts Casey (Curculi- 
onid#), among the anthers, feeding upon the pollen, and 
pairing. They seemed more likely to secure self-pollination, 
though in their slow movements to other plants cross-pollina- 
tion might be effected. The flowers bloom from April 24th 
to May 15th. 
TRILLIUM RECURVATUM Beck.—This is a common plant, 
blooming from April 8th to May 16th. The stems grow a 
lwdm. high and bear single flowers, which are sessile upon 
the circle of three leaves. The sepals are green and reflexed. 
The petals are erect, arch over the stamens and are narrowed 
at base and tip. They are dark purple. The filaments and 
‘tigmas are of the same color, but the anthers are nearly 
black. The anthers are long and rigid, having a very broad 
‘onnective which is produced above into a blunt point. They 
ma rather rigid cone over the pistil, so that the pollen 
‘an hardly be eaten or collected by insects. I find no nectar 
Mr odor, in fact nothing to induce insect visits, except the 
Muple color. It is possible that small flies resort to these 
lowers at night. The stigmas become elongated and re- 
Pitas so that with their convoluted edges they are quite 
ely to receive pollen from the anthers.
