223. Paspalum setaceum Mx, Downy Water-grass. Sandy soil, cen- 

 tral and western Kansas; frequent. June. (AS) 



224. Eriochloa punctata Hamilton. {E. polystachya H. B. K.) Dotted 

 Wool-grass. Dry prairies, S. and S. W. K. ; occasional. July. (AS) 



225. Syntherisma filiformis Nash. (Diyitaria Koeler.) Slender Crab- 

 grass. Sandy soil, E. K. ; frequent. July. (ASU) 



226. Syntherisma lineaeis Nash. {Panicum Krock). Smooth Crab-

 ger-grass. Fields and waste places, eastern and middle Kansas, and 

 spreading westward, should be utilized wherever it becomes too common. 

 Frequent and close mowing of lawns in this sunny climate disheartens blue- 

 grass and encourages the growth of crab-grass; pasturing, if not too close, 

 reverses that. June. (ASU)

 and Kunth.) Little Arm-grass. Extreme southwest Kansas; 3-7 dm.; 

 stoloniferous; not common. June. (AS) 



230. Leptoloma capillaris (L ) (Panicumh.) Old-witch-grass; Tickle- 

 grass. In plowed fields all over the state; a real pest in barren fields, and 

 often in stubble-fields of eastern Kansas; 3-6 dm.; common. July. 



231. Leptoloma barbipulvinata (Nash.) {Panicum Nash.) Yellow- 

 stone Witch-grass. Open ground, C. and N. W. K.; 1-4 dm.; occasional.

234. Leptoloma dichotomiflora (Mx.) {Panicum geniculatum Muhl.) 

 Great Spreading Witch-grass. Rich damp soil, with stout creeping root- 

 stocks simulating a perennial; commonly 10-18 dm. long; becoming frequent 

 in E. K., especially in rich soil near houses, barns, parks, etc. July. (ASU) 

 An excellent forage grass and worthy of cultivation, except that it is liable 

 to smut.

 Panic-grass. Rich dry or moist soils, where the air is not too dry; in west- 

 ern Kansas in valleys only; farther east on hillsides and uplands as well; 

 6-12 dm. high; very common. July. (ASU)
