 Kings River.

EQUISETACE/E. Horse-Taii. Famii^y. 

 Equisetum robustum A. Br. Giant Horse-Tail. This is 

 the tall rush commonly known by the above name. It grows 

 to a height of several feet and the stems are almost half an inch 

 in diameter. All the horse-tails are easily distinguished by the 

 character of having the stems jointed, each joint fitting into the 

 one just below. The spores are borne in a spike at the top of the 

 stems. This species was seen only along Kings River. 



OPHIOQLOSSACE/B. Grape-Fern Famii,y. 

 Botrychium simplex Hitchcock. Grape-Fern. This little 

 fern, so small as to be almost invisible, consists of two parts. 

 The sterile frond is a single lobed leaf, ovate-cordate in outline ; 

 the fertile frond is simple or branched, and bears tiny globular 

 sacs which are full of spores. This is very rare, and was seen 

 only near Bubbs Dome, growing near the edge of the water. 



FILICES. Fern Famii^y. 



Pellsea Breweri Eaton. Rock-Fern. (Fig. i.) Densely 

 tufted and woolly at base. Stems dry and brittle, brown, glossy, 

 numerous. Frond simply pinnate, with the lower divisions con- 

 sisting of two ovate, pointed lobes extending almost to the base, 

 the upper ones narrower and entire. 



This is very common around Bullfrog and East I/akes.
