List of Species 



Equisetum inter mediiun (A. A. Eaton). Fern worts are 

 seldom found in the desert. This species was frequent in wet 

 places. The remains of fertile catkins indicate that its sea- 

 son of fruiting is much earlier. 132. 



Adiantuui rimicola Slosson. Venus' hair Fern. About 

 a dozen plants were found under a sandstone cliff at Reservoir 

 Canyon. The species is what is ordinarily known a.sAdiantum 

 capilliis-vcncris. 88 



Typha latifolia. L. Cat-tail. This common inhabitant 

 of wet places was more luxuriant than I have ever seen it else- 

 where, reaching a height of ten feet or more. At Reservoir 

 Canvon and in reservoirs at Tuba. 



Polypogon monspcliensis (L.). This small grass, a native 

 of Europe, may be found in many moist spots. It has much 

 the aspect of the common corn grass (Sctaria) but is much 

 smaller. Stock is not very fond oft it. 124 



Phragmitcs Phragmitcs (L.). Reed. A reed-like grass 

 well known for its tall culms in wet places. At Tuba the 

 leaves are always covered with green plant lice. 85 



Disticldis stricta (Tovr). Saut-grass. Abundant on the 

 Government farm in Moenkopi Wash and elsewhere. Called 

 "Johnson grass." It spreads by underground runners, is hard 

 to eradicate, and is regarded as a pest. 66 



Ccnchrus Caroliniamis Walt. Saxd-bur. This familiar 

 plant finds the sandy soil of the orchard at Tuba quite to its 



liking. 92 



Elcocharis palustns L. \ characteristic wet-ground plant
