A NEW SALICORNIA. 

 BY IVAR TIDESTROM. 



On August 6, 1912, Messrs. Kearney and Shantz collected 

 some very interesting plants in the Toele Valley, some three 

 miles northwest of Grantsville, Utah. The place where the 

 plants grew is situated south of the Great Salt Lake and near 

 the base of the Stansbury Range. The principal species col- 

 lected bore the aspect of the desert flora — the Chenopodiaceae 

 and Compositae being well represented. In the collection there 

 is a species of Salicornia hitherto unknown, for which the fol- 

 lowing name and diagnosis are proposed: 



Salicornia utahensis. 



Perennis basi lignosa, 2dm. plus minusve alta; caulibus pluribus de- 

 cumbentibus vel erectis, ramis erectiusculis ; articulis eaulium 15-18 mm. 

 longis, 3-5 mm. crassis, ramorum tenuioribus; spicis 7-10 articulatis, 15- 

 20 mm. longis, crassitudine plus minusve 4 mm. 



Type in the U. S. National Herbarium, Kearney and Shantz, No. 

 3249, collected near the shore of the Great Salt Lake in strongly saline 

 soil, moist to the surface. 



Distinguished from Salicornia ambigua and S. subterminalis (the one 

 of the Atlantic, the other of the Pacific Coast) by its short, thick spikes. 

 In the former the spikes are from 18-20 jointed, while in the latter the 

 number of joints is 13 or more, consequently much longer than in our 

 species, while the thickness of the spikes in the old species is scarcely 

 more than one-half of that of S. utahensis.
