405. Uniola latifolia Mx. Broad-leaf Spike-grass. Shaded, high earthy 

 creek banks and rocky woods, E. K. ; frequent. August. (ASU) 



406. Briza media L. Quaking-grass. Occasional, in gardens. 



407. Briza maxima L. Large Quaking-grass. Cultivated for its beauty. 



408. Dactylis glomerata L. Orchard-grass. Introduced for good grass 

 crops; escapes and grows naturally in rather moist soils. 



409. Cynosurus cristatus L. Dogtail-grass. Street parks of the cities 

 of E. K., and other waste places; introduced as adulteration in seeds of 

 other grasses; rare. June. 



410. Poa annua L. Annual Bluegrass; Low Spear-grass. Waste places 

 and cultivated fields, E. K, ; traveling westward. May. (ASU) 



41L Poa compressa L. Flat-stem Bluegrass. Damp places on prai- 

 ries and in fields, nearly all over Kansas; apparently native, having been 

 here before ettlement; yet not common. June. (ASU) Makes a very 

 compact sod; foliage deep blue-green; lives in spots too hot for Kentucky 

 bluegrass. 



412. Poa triflora Gilibert. (P. serotina Ehrh. ) Fowl-meadow Blue- 

 grass, Wet meadows, eastern two-thirds of the state; common. July. 

 (ASU) 



(For Poa flava L. see Triodia fiava, ante. No. 374.) 



413. Poa pratensis L. Bluegrass ; Kentucky Bluegrass. On rich limy 

 soils where slightly shaded during the hottest days of summer. May-June. 

 Introduced, but not yet thoroughly naturalized, except perhaps in shade of 

 hills, tall trees, and buildings. Should be but sparingly mowed in heat of 

 summer. Too close mowing of lawns during the drier weeks of July and 

 August exposes the roots of this grass to the hot sunshine and either kills 

 it outright or so weakens it that the crab-grasses and pigeon-grasses choke 

 it to death later. 



414. Poa trivialis L. Rough Bluegrass. Meadows and waste places, 

 Brown and other counties of N. E. K. ; not naturalized. June. 



415. Poa sylvestris Gray. Sylvan Spear-grass. Wooded meadows, 

 Douglas county eastward ; not common. June. (SU) 



416. Poa autumnalis Muhl. Spring Spear-grass. Woods, extreme 

 eastern Kansas ; not common. March-April. Wonder if identification of 

 this grass is correct? 



417. Poa alsodes Gray. Grove Spear-grass. Thickets along streams, 

 E. K.; frequent. May. (ASU) 



418. Poa wolfii Scribn. Silky Bluegrass. Dry soils, E. K. ; occasional. 

 May. ( A ) 



419. Poa arachnifera Torr. Texas Bluegrass. Cultivated occasionally 

 for pasture in S. W. K. ; with its strong perennial rootstocks, well adapted 

 to hot dry lands of summer, it makes a more reliable pasture or lawn than 

 our Kentucky bluegrass, P. pratensis. May. (S) 



420. Poa arida Vasey. ( Heretofore listed as P. andina Nutt. by er- 

 ror.) Prairie Spear-grass. Bottom lands, Dickinson county, northward 

 and westward ; not common. July. (AS) 



421. Poa buckleyana Nash. Bench-land Spear-grass. Dry soil, Chey- 

 enne county ; not common. July. 



422. Glyceria canadensis Trin. Manna-grass. Marshes, E. K. ; not 

 common. July. (ASU)
