150 BOTANY OF THE DEATH VALLEY EXPEDITION. 



margins, conspicuously venose-reticulate, 1.5 to 2 cm. long, reflexed or divaricate on 

 petioles 1 to 2 mm. long, with smaller leaves axillary-fasciculate; inflorescence made 

 up of 2 to 4 distinct spheroidal congested clusters (about 1.5 cm. in diameter and 

 about the same distance apart) of dowers, spicately arranged at the extremities of 

 the branches; bracts subtending the clusters similar to the leaves, the uppermost 

 much smaller; calyx lobes 1-nerved; corolla in dried specimens brownish purple, 

 weathering to straw color, tube tomentose without, lobes widely spreading; anthers 

 sessile in the throat of the corolla. 



"This plant is closely related to B. marrvbiifolia, but is readily distinguished by its 

 Bpicate flower clusters and narrow leaves. In that species the single spherical head 

 terminates the branches upon a well-defined peduncle, while the leaves vary from 

 ovate to obovate with cuneate base. 



"Type specimen in the United States National Herbarium; collected in 1877 near 

 St. George, southern Utah, by Edward Palmer. 



"The plant has been collected but twice, once in the typo locality and now at the 

 foot of a limestone cliff just north of Mountain Springs, near Olcott Peak, Charleston 

 Mountains, Nevada {No. 386;. The former is the most northerly locality known for 

 any species of the genus. B.mamliifoUa is known in the United States only in 

 southern Texas."

Erythreea vennsta Gray, Bot. Cal. i. 479 (187(5). Type locality not given ; range, 

 "through all the southern part of the State, and extending (mostly ill a smaller form) 

 along the Sierra Nevada to Sierra Co., up to about 4,000 feet." 



On the western slope of the Sierra Nevada (Nos. 1287, 1810).

In the high Sierra Nevada (Nos. 1580, 1630, 1675, 1732). The specimens of No. 1675 

 are very snntll and 1-flowered, so that they closely resemble (i. simplex. The seeds, 

 however, which have been well described heretofore, clearly distinguish the two 

 species.
