Lake Maxinkiickee, Physical and Biological Survey 313 

 349. BULBOUS BUTTERCUP 



RANUNCULUS BULBOSUS L. 



Not common ; only 1 clump of plants seen. This was found in 

 flower by the Arlington depot May 24 and June 4, 1901. The 

 seed was probably brought in by the railroad. 



350. HISPID BUTTERCUP 



RANUNCULUS HISPIDUS Michx. 



Not abundant; collected on Long Point back from the shore of 

 the lake; found also near Green's marsh where it was in flower 

 May 13, 1901. 



351. WHITE WATER-CROWFOOT 



BATRACHIUM TRICHOPHYLLUM (Chaix) F. Schultz 



During the early part of the survey this did not appear to be 

 a common plant. A few were found by the green boathouse near 

 Norris Inlet in 1900, and in 1901 a patch was found in flower June 8 

 in Lost Lake near the east shore. In later years it appears to have 

 increased a good deal. In 1904 some was found on shore north of 

 the icehouse, and on November 16 of that year it was still as green 

 as ever, in Outlet Bay. In 1907 and 1908 there were large patches 

 along the north shore of Long Point. 



The plants remain all winter, and are broken into fragments 

 along shore by the winds and waves of March and April, each 

 fragment taking root and growing. The white flowers are rather 

 small and inconspicuous, giving the water surface a powdery, dusty 

 appearance. 



Frequently, in late autumn, the plants are covered by a dense 

 growth of diatoms. 



352. PURPLISH MEADOW-RUE 



THALICTRUM DASYCARPUM Fisch. & Lall. 



Probably not common ; only one plant collected and its identifi- 

 cation somewhat doubtful. We have found in meadows near Fort 

 Wayne plants that appeared intermediate between this species and 

 polyganmm. 



353. EARLY MEADOW-RUE 



THALICTRUM DIOICUM L. 



Common on the east side on wooded hillsides, also found west of 

 the Palmer House. Abundant on the hill fronting Overmyer's field. 

 One of the earliest and most graceful of our spring flowers, but 

 by no means showy. Noted in blossom April 23, 1901.
