crosswise or very faintly so, varying somewhat in length, and free of 

 tubercles or covered with them more or less all over the surface. I have 

 not seen a specimen of the typical form of this species and the data given 

 in the key have been obtained from published studies. Doubtless all Indiana 

 plants belong to this variety.

471 A. BULBOSTYLIS [Kunth] C. B. Clarke 



''Plant bearing crowded sessile spikelets at the bases of the leaves; spikelets of the 

 terminal umbel rather crowded, 3-10 mm long, longer than their pedicels" (Rhodora 

 40: 395. 1938) 1. B. capillaris. 



Plant not bearing sessile spikelets at the base of the leaves; lateral spikelets of umbels 



2.5-6 mm long, shorter than the pedicels; pedicels unequal, 0.1-10 mm long

1. Bulbostylis capillaris (L) C. B. Clarke. (Rhodora 40: 395. 1938.) 

 (Stenophyllus capillaris (L.) Britt.) This change of name came too late 

 to change the name on the map. Map 402. I have the typical form of this 

 species from Elkhart, Kosciusko, Lagrange, St. Joseph, and Starke Coun- 

 ties. The map shows both the typical form and the variety. 



This plant is infrequent in the northern part of the state and rare in the 

 southern part. It is found in very dry, sandy soil, usually in fallow fields 

 and clearings, on open, sandy knolls and dunes, and the variety sometimes 

 in residual soil on the crests of sandstone ridges and on cliffs. 



Southern Maine to Minn., southw. to Va. and Mo. 



la. Bulbostylis capillaris var. crebra Fern. (Rhodora 40: 395. 1938.) 

 This variety has the same habitat as that of the species and ranges through- 

 out the state. Only thorough field study will convince me that this variety 

 is distinct in Indiana.
