GRASS-FLORA OF TOLLAND, COLORADO, AND VICINITY 



127 



Genera Which May Be Found with Further Study. — While 

 the present list is probably as nearly complete as any first-published 

 list is likely to be, yet there are certain genera of which we have 

 no records which it would appear should be represented in the 

 collection. All of the following have been reported either from 

 Idaho Springs or Georgetown which are in the same general area 

 of the state and hence may be expected at Tolland: Syntherisma 

 (crab-grass), Oryzopsis (mountain-rice), Munroa (false buffalo-grass), 

 Catabrosa (water whorl-grass), Puccinellia (meadow-grass). It is 

 likely also that additional species will be found in the genera 

 already reported. 



Extent of the Grass-Flora. — The present writers have examined 

 from the area under consideration specimens having 290 different 

 herbarium numbers which represent 26 genera and 79 species. When 

 the small area of collection is considered and its high altitude (8,500- 

 9,500 feet), together with the extremely cool climate — too cold for 

 "fruit trees" or cereal grains — this seems a rather large number of 

 species and genera. A tabular comparison of our area with that of 

 the entire state of Colorado may be of interest. The Colorado 

 statistics are from Rydberg.
