 527. THYME-LEAVED PIN-WEED 



LECHEA MINOR L. 



Rather common in the dry sandy ground north of Lost Lake, 

 associated with Crocanthemum canadeTise ; some plants in front of 

 the Mihtary Academy and some on the beach beyond Norris Inlet. 

 Flowers inconspicuous. The prostrate runners or stdlons with 

 their leaves arranged symmetrically, are the most attractive fea- 

 tures of the plant, especially in winter when the leaves turn bronze 

 red. The leaves persist throughout the winter. Noted in flower 

 about the middle of August. 



Family 101. Violace^. Violet Family 



528. BIRD'S-FOOT VIOLET 



VIOLA PEDATA L. 



Found only along the ridge on the east side of Lost Lake and 

 its outlet, back of Walley's woods, and along the railroad. Its 

 distribution is peculiar and interesting. Its range covoi-s a large 

 area, occupying most of the eastern United States, but within that 

 range it is only where some favored sandy or sandy clay hill 

 suitable to its growth occurs, that this plant is to be found. There 

 may be whole counties without a plant of this species, and in 

 Indiana it is usually found in only small patches, though abundant 

 within the limited areas in which it occurs. It (especially the bi- 

 color form) is the largest and in some respects the most handsome 

 of the violets. It has two flowering seasons, one in late spring 

 when it blossoms abundantly, and one in late autumn when it pro- 

 duces only a few flowers. In flower May 2 and later along the rail- 

 road southwest of the lake. In blossom October 24 and 25 along 

 Lost Lake outlet ; in 1900, some buds, overtaken by cold, remained 

 all winter, but did not blossom in spring. In 1907, flowers were seen 

 September 11 and 29 by the birch swamp along the railroad, and 

 on October 14 they were still abundantly in flower. 



We did not find any of the bicolor form with the upper petals 

 black and velvety. It is likely to occur, however, wherever the 

 other form is found. ' 



529. EARLY BLUE VIOLET 



VIOLA PALMATA L. 



Common in dry shady places, also on dry banks along the rail- 

 road. One of the early spring flowers which continues blossoming 

 for a month or more.
