167. M. vestira Hook. & Grev. In ponds in many places in the 
tate; Fairmont, Bradshaw, Minden, Geneva. Apparently not 
occurring east of the Blue River. The Fairmont specimens col- 
lected in 1890 agree with the variety tenuifolia in the hairiness, 
and shape of the leaflets, but nearly all the specimens collected 
hi year (1891) fully agree with the specific characters of M. 
vestita. A few specimens were received which were more hairy, 
and whose leaflets were narrower, but upon investigation these 
were found to be terrestrial forms. In some cases these tenui- 
folia-like forms were connected directly with the iarger smooth 
and broad leaved aquatic forms. The season of 1890 was a very 
dry one which probably accounts for the smaJl size of the plants 
and the hairiness and narrow growth of the leaflets. (Bessey).
