167. M. vestita Hook. & Grew In ponds iu many places in the 

 State; 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 

 this 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. Iu some cases these teuui- 

 folia-like forms were connected directly with the larger smooth 

 and broad leaved aquatic forms. The season of 1 -'.»(> was a very 

 dry one which probably accounts for tin- small size of the plants 

 and the hairiness and narrow growth of the leaflets (Bessey).
