160 BOTANY OF THE DEATH VALLEY EXPEDITION. 



The. species appears to have been collected only in the original locality l>y Dr. 

 Streets; at Yucca Mohave County, Arizona, in 1881, by Marcus E. Jones; and near 

 Campo, in the Colorado Desert, in 1889, by C. K. Orcntt. By the discovery of the 

 latter locality, together with those in the Death Valley region, the range of the 

 species is established as confined to the Lower Sonoran zone of the desert. 



Phacelia perityloides Coville, Proe. Biol. Soc. Wash. vii. 75 (1892). Typo 

 locality as given below. Plate XV. 



"Suu'rutesecnt perennial 10 to 20cm. high, diffusely branched, densely leafy ; stem, 

 as well as branches, leaves, and calyx, viscid with glandular hairs, or at the base 

 densely villous-toinentose ; leaves alternate; petiole 7 to 15 mm. long; blade orbicu- 

 lar, with truncate to cordate base, crenate-dentate or even lobed, 7 to 12 mm. in di- 

 ameter, the hairs shorter than on the stem and petiole; flowers in loose racemes 

 terminating the branches; pedicels 3 to 5 mm. long; calyx about 4 mm. long, the 

 lobes oblong-spatulate, obtuse; corolla cream-white, sparingly glandular-hairy, 

 twice as long as the calyx, its narrowly cam-panulate tube longer than the calyx and 

 its short orbicular lobes abruptly spreading; appendages 10 scmilanccolate, vertical 

 lamella) free from the filaments; the 3 veins of each corolla lobe continuing distinct 

 to the base of the tube ; stamens included in the throat of the corolla ; anthers oblong ; 

 ovary and included style sparingly short-hairy; style tips very short, divergent; 

 capsule narrowly ovate, bluntly acute, 3 to 4 mm, long; seeds apparently very nu- 

 merous, oblong, anguhite by compression, scrobteulate, 5 mm. long. 



"The plant closely resembles a small congested specimen of Peritylc emoryi. The 

 form of the leaves is very similar to that in I', rotundifolia, but the plant, while be- 

 longing to the subgenus Eutova, differs from all its species in being suff'rutescently 

 perennial. The cream-white corollas form another conspicuous character. 



"Type specimen in tho United States National Herbarium, No. 524, Death Valley 

 Expedition; collected March 31, 1891, in Johnson Canon, Panamint Mountains, Cali- 

 fornia, by Frederick V. Coville." 



Phacelia pulchella Gray, Proc. Amer. Acad. x. 326 (1875). Type locality, "S. Utah." 



In the Vegas Wash, Nevada (No. 402). Put one specimen was collected and that 



only in early flower. The calyx is 7 to 9 mm. long* and the corolla one-half longer to 



nearly twice as long, while the appendages of tho corolla are semilinear rather than 



somioblong. The plant resembles this species, however, more nearly than any other. 



Phacelia ramosissima Hook. Fl. Bor. Amer. ii. 80 (1838). Type locality, "dry 

 rocky plains of the Columbia, near the Priest's Rapid, 'and at the Stony Islands, 

 N. W. America." 



Near Crystal Spring, Coso Mountains (No. 932), and in the vicinity of Fort Tejon 

 (No. 1154). 



Phacelia rotundifolia Torr. Pot. King Surv. 253 (1871). Type locality, "Southern 

 Utah." 



In Surprise (No. 033) and Hall (No. 691) canons, Panamint Mountains. This is a 

 Lower Sonoran species of the desert region of California, Nevada, Utah, and Arizona. 



Phacelia tanacetifolia Benth. Bot. Reg. xx. t. 1696 (1834). Type locality, "Cali- 

 fornia." 



Tejon Mountains (No. 1189). 



This plant was probably first described in Trans. Hort. Soc. Lond. ser. 2. i. 479, but 

 the dates of issue of the several parts of that publication are not precisely known. 



Lemmonia californica Gray, Proe. Amer. Acad. xii. 162 (1877). Type locality, 

 "San Bernardino County, California, on Bear Valley Creek, on the headwaters of 

 the Mohave River." 



Observed only on the western slope of Walker Pass (^{o. 1022), and at a few points 

 between Kernville and Caliento.
