VIOLACEAE. 
Viota Lancrouata, Mi.. W.— The flowers are small. 
The petals are white, the lower one streaked with purple, 
lateral not bearded. The flower is not adapted to pollen- 
collecting bees. The spur is short. From the tip of the 
style a narrow passage leads to the base of the tube, a 
distance of about 4mm. The stigma is beaked and only 
surpasses the anthers a little, but enough to prevent self- 
pollination. 
Insects land on the upper petals and approach the nec- 
tary from above. The flower is therefore sternotribe, the 
place of pollen-contact being the under surface of the 
proboscis. Ja. 19-Ap. 26, 16 visitors observed, Ja. 19-
