FLORA OF HONEY LAKE VALLEY. 7 



eut vegetation from that of the drier alkali plain, occurs. Sarcoba- 

 tus is less abundant and a more or less dense growth of Salt Grass, 

 Distichlis spicata, affords the principal summer pasturage for num- 

 erous horses and milch cows. In this natural pasture we also find 

 Triglochin concinna, Ranunculus Cymbalaria, Cressa Cretica 

 Truxillensis here, as elsewhere, the host of Alcidium Cressa, 

 Nitrophila occidentalis, here more abundant than I have seen it 

 elsewhere, Adenostegia maritima, Alropis Icevis, Deschampsia 

 calycina, the two latter not as abundant as in the wet adobe mead- 

 ows of the Tule Confederacy, Scirpus pungens, Scirpus Nevadensis 

 and species of Juncus. 



Mr. Jones informs me that my Triglochin concinna (Erythea 

 iii, 117, July 1, 1895) is the same as his T maritima debilis 

 (Proc. Calif. Acad. Ser. 2, v, 722, October 3,1895) and the T.palus- 

 tris of Dr. S. Watson (in Bot. King). It was first described from the 

 salt-marshes of San Francisco Bay at West Berkeley, and Newark, 

 Alameda County, where it grows along with T. maritima. It was 

 also collected by Mr. Jones at Johnson, Utah, at an altitude of 

 5,000 feet, on May 23, 1894, and by me on the margin of Dry Lake, 

 near Rosamond, Kern Couuty, in 1896. It is here quite common 

 and is frequently the host of a pretty Urediue. Mr. Jones remarks 

 (ibid?) that this plant "grows on clayey, alkaline flats at Johnson, 

 Utah, where no other plant will grow." 



Triglochin maritima grows luxuriantly in the marshes of a delta 

 formed by streamlets running down from the hot springs. It is 

 usually in company with species of Juncus, Scirpus and Eleo- 

 charis, where the ground is too wet for Salt Grass. 



Along the banks of the yet steaming streamlets, and only there, 

 so far as our search revealed, grew a fringe of Polypogon Mo?i- 

 speliensis, Panicum capillare, a Mimulus, and Erigeron Canadensis 

 in dwarf form. 



On a ridge of blown sand beside the lake, and in several saline 

 spots in the Tule Confederacy, au annual Suseda occurs which is 

 often absolutely strict in habit, though sometimes branched from 

 the base. It was not in fruit nor even in flower at the time these 

 observations were made. 



Passing from the alkali soils at the lake-shore level, upwards to 

 he gravelly tracts which either overlie, or occur at the margin of,
