THE GRASSES OF KANSAS. 



By A. S. HITCHCOCK, Manhattan. 



The following is a list of the grasses of Kansas, as represented by speci- 

 mens in the herbarium of the Agricultural College. The nomenclature and 

 arrangement is that of the "List of Pteridophyta and Spermatophyta" re- 

 cently issued as a Memoir (vol. V) of the Torrey Botanical Club. For this 

 reason no extended synonymy is given. Every citation has been verified, ex- 

 cept where included in quotation marks. The citations not verified are as 

 follows:

Professor Scribner has kindly answered several questions concerning no- 

 menclature, and has aided in the determination of some of the species. 



I also wish to thank the Missouri Botanical Garden for the privilege of 

 using the excellent library there collected. Several original descriptions 

 not in my private library were photographed, such as Lamai'ck's Encyclo- 

 pedia, Walter's Fl. Car., and Hooker's Fl. Bor. Am. I have now either the 

 original or a photograph of the original, of all the descriptions except those 

 enumerated above. 



After the citation of the original description is given the type locality as 

 it appears in the work cited. 



TRIPSACUM L. Syst. Ed. 10, 2: 1261 (1759). Includes two species, T. 

 hermaphroditum, and the following: 



T. dactyloides (L.) L. Syst. Ed. 10, 2: 1261 (1759). America. Wet places, 

 west to Saline and Barber. 



ANDROPOGON L. Spec. PI. 1045 (1753). Twelve species; N. A. A. di- 

 varicatum, nutans, alopecuroides, virginicum. 



A. Hallii "Hack. Sitz. Akad. Wiss. Wien, 89: 127 (1884)." The typical form 

 occurs through the western part of the state, but it seems to be connected 

 with A. provincialis Lam. by intermediate forms which are abundant through 

 the central counties. It would seem best to call this a western variety under 

 the name A. provincialis, var. Hallii (Hackel).
