Gerardia ASPERA I)ou(jl.\ Beiitli. in D. (>. Prodr. 10:517. 

 1846. Rough Purple Gerardia. 



Gerardia longiiolia Benth. Comp. Bot. Mag. 1:208. 1835. Not Nuttall. 



Stem somewhat branched, 1 — 2 feet high, hispid ulous- 

 scabrous; leaves narrowly linear, rough-hispid; pedicels 

 equaling or about twice the length of the calyx; calyx- 

 lobes triangular-lanceolate, shorter than the tube; corolla 

 one inch long, purple, glabrous within, pubescent without. 



This is a prairie species growing in a dry soil, and ranging 

 from Indiana to Michigan, Minnesota, South Dakota, and 

 Nebraska, south to Missouri, Arkansas, and Texas. The 

 flowers open in August and September. 



Within our limits this Gerardia seems to be infrequent. 

 Our specimens are from Emmet and Decatur counties. 

 In the latter locality only a single specimen was found, 

 and this one was growing with Gerardia auriculata of 

 which there was a considerable colony. The State Uni- 

 versity herbarium has specimens from Delaware, Henry, 

 and Lyon counties. Professor Pammel reported the species 

 from Woodbury county; Professor Hitchcock from Story 

 county; and Messrs. Barnes, Reppert, and Miller from 

 Muscatine county.
