FLOWERING PLANTS AND FERNS OF INDIANA. 805 



of the black walnut. In such localities it reaches a diameter of 

 nearly two feet. It also occurs in dry, sandy or gravelly soil, but 

 in much less perfect development. The early shedding of the 

 leaves is a serious objection to its use in lawns or yards. 



It flowers from early in May till in June, depending upon its 

 location.

ASTRAGALUS L. 

 A. Plattensis Nutt. 



This species is credited to Indiana in the Manuals of Gray and 

 Britton and Brown. So far as I am able to discover, the species 

 has been reported from but one station, Lafayette Junction in 

 Tippecanoe County. It was only once found in this station, but 

 abundant herbarium material confirms its appearance at that 

 time. It was probably brought in by the railroads, and main- 

 tained itself for a single season on the dry, gravelly hills charac- 

 terizing its station. It is certainly not of general occurrence in 

 the State. 



A. Carolinianus L. Carolhaa Milk-vetch. 



(A. Canadensis L.) 



Quite common along streams and lake margins in various 

 counties of the State. 



In July and August, when in full bloom, it is one of the most 

 conspicuous plants in the regions in which it occurs.

STYLOSANTHES Sw. 

 S. biflora (L.) B. S. P. Pencil-flower. 



(S. elatior Swartz.) 

 Very rare in our bounds. Three stations are reported. From 

 the "barrens" near Palmyra (Barnes) and from Gibson and Posey 

 (Schneck). In all cases the form occurred in dry soil and was 

 noted as rare.
