NOTES ON CERTAIN LEGUMINOSAE.

Tue recent note by Mr. Walter Deane, in Ruopora for November, 
1910, has prompted me to publish the following information in regard 
to Desmodium canescens (L.) DC. and other species of the same family. 
Desmodium canescens (L.) DC. I first collected Sept. 4, 1898, in 
Natick, Mass. The station at that time contained but a few vigor-

Lespedeza capitata Michx., var. velutina (Bicknell) Fernald, I have 
collected but once, in dry sand at Pelham, N. H. It is a very definite 
variety, and the name is well chosen, for its soft tomentum is entirely

Vicia tetrasperma (L.) Moench. grows abundantly in the edge of 
oak woods near the salt marsh at East Weymouth, Mass. It had 
already begun to fruit at the time of its collection, June 6, 1908. I 
have found it beside the sea at Castine, Me., and on a railroad em-
