68 BOTANY OF THE DEATH VALLEY EXPEDITION. 



tho capsnles oblong, attenuate into the stipe, abruptly tapering at the apex; and the 

 seeds without a groove between the hiluni and the body. Tho samo plant as ours, 

 but without mature fruit, was collected by Xautus de Vesey near Fort Tejou in 

 1857-58. 



"Typo specimen in the United States National Herbarium, No. 1107, Death Valley 

 Expedition; collected June 24, 1891, on Oaliente Creek, a few miles above Caliente, 

 Kern County, California, by Frederick V. Covillo. 



"The characteristic distribution of this variety was not ascertained. It might be 

 expected to be a form modified by proximity to the Mohave Desert, but tho type form 

 enters the western portion of this desert in at least one place, Tehachapi Pass; and 

 flowering specimens, presumably of the type form, were seen in April about forty 

 miles from Mohave, on tho road from that place to Searles's borax establishment." 



Oxystylis lutea Torr. & Frem. in From. Second Rep. 313 (1815). Typo locality, 

 "on the Margoza river, at tho foot of a sandy hill; only seen in one place, but 

 abundant there." 



Collected in Furnace Creek Canon (No. 223), in the bed of the Amargosa River, 

 about 10 kilometers south of Salt Wells ; in the sandy mesa immediately northwest of 

 Saratoga Springs ; and about the sand-hills 3 kilometers northeastward from the same 

 point. 



Tho plant is an annual, with a stout, erect, usually uubranehod stem often reach- 

 ing a height of 1 meter. Tho valves of the capsules, each with its embraced seed, 

 had already dropped off when tho specimens were collected, in January. The leaves 

 also wore dried and broken off by tho wind, yet tho remaining skeleton of the plant, tho 

 naked stem, and the old fruit clusters, rendered it conspicuous. In the hitter three of 

 the localities mentioned above, all in the valley of tho Amargosa Rivor, both above 

 and below its bend at Saratoga Springs, the plants are abundant. It was at or near 

 the last station that Fremont, on the 28th of April, 1844, discovered this plant; and 

 it has never been collected since. He records the finding of it as follows (loc. cit. 

 264): " [We] reached a large creek of salt and bitter water, running in a westerly 

 direction, to receive tho stream bed we had left. It is called by Spaniards Amargosa— 

 the bitter water of the desert. Where we struck it, the stream bends; and we con- 

 tinued in a northerly course up the ravine of its valley, passing on the way a fork 

 from the right, near which occurred a bod of plants, consisting of a remarkable new 

 genus of Crueifera3." » 



It is unfortunate that at the second collecting of such an interesting monotypio 

 genus the specimens should have been poor ones.
