74 BOTANY OF THE DEATH VALLEY EXPEDITION. 



Malveopsis rotundifolia (Gray) Proc. Amer. Acad. vii. 333 (1868), under Mal- 

 rastrum; Kuntze, Rev. Gen. PL i. 72 (1891). Type locality, "sand bills at Fort Mo- 

 have," Arizona. 



This was observed on the mesa west of Bennett Wells (No. 481), and at the foot of 

 the Funeral Mountains, opposite the same place; in the dry wash of the Amargosa, 

 between Salt Wells and Saratoga Springs ; in Resting Springs Valley ; on the western 

 slope of the divide northwest of Towner's; in Furnace Creek Cafmn (No. 452); in 

 Pananiint Valley, at the mouth of Hall Canon; in Surprise Canon, Pauainint Moun- 

 tains; and near Swansea. The plant is an annual of frequent occurrence on grav- 

 elly mesas and in washes, always growing in the Lower Sonoran zone. Its flowers 

 are very striking, the globular pink corolla, with a red spot at the base of each 

 petal, having given it the local name of " lantern flower." 



Sida hederacea (Hook.) Fl. Bor. Amer. i. 107 (1830), under Malta— Dong). MS. ; 

 Torr. in Gray, PL Fendl. 23 (1819). Type locality, "in the interior districts of the 

 Columbia," probably in Oregon. 



Near Lone Pine (No, 951). 



Sphaeralcea munroana (Lindl.) Pot. Beg. xvi. 1. 1306 (1830), under Maha— Dougl. 

 MS.; Spaeh. Hist. Veg. iii. 353 (1834). Type locality, "upon the barren plains of 

 the Columbia." 



The plants referred here are not, in most cases, in condition for critical determina- 

 tion. They all have the characteristic leaves of the species, and their petals, when 

 fresh, were scarlet. Specimens of No. 868 alone bore mature fruit. The identity 

 of all the plants supposed to belong to this species is so uncertain that a detailed 

 statement of localities would be of little value. Specimens were collected on the 

 south slope of Browns Peak (No. 176); near Furnace Creek Ranch (No. 352); in 

 Johnson (No. 550) and Surprise (No. 634) canons, Pananiint Mountains; and at the 

 western foot of the Inyo Mountains, near Swansea (No. 868). 



CHEIRANTHODENDRACEiE. 



Fremontodendron californicum (Torr.) PL From. (1853), under FremonUa. 

 Type locality, "sources of the Sacramento, in the northern part of the Sierra Ne- 

 vada of California." 



The generic name FremonUa was first applied 1 by Torroy to the plant now known 

 as Sarcobatw vermiculatus, but the name Sarcohatttx had already been given to the 

 genus by Nees von Esenbeck, and FremonUa became a synonym. Baillon has re- 

 ferred * the later FremonUa, our plant, to a Mexican genus Cheirantkodendron, an 

 older name for Cheirosiemon H. P. K., but Dr. Torrey, when he published the genus 

 as FremonUa, knew the genus Cheirosiemon also and pointed out some of the diff- 

 erences. Dr. Gray in one of bis later papers, 3 after a mature consideration of the 

 verified characters of the two genera, considered them distinct. He retained, how- 

 ever, the now untenable name FremonUa, in place of which I propose the name 

 Fremontodendron, 



On the summit of Walker Pass, as we came over from the desert, we first saw this 

 beautiful tree (No. 1021). It was then in full bloom, and its masses of yellow flowers 

 were conspicuous among the nutpines and gray-leaf pines of the western Sierran slope. 

 We passed into its belt again when we crossed the divide north of Havilah, a third 

 lime on the divide north of Walker Basin, and a fourth time on the slope of the Sierra 

 Nevada west of Tehachapi Valley. On some of the peaks south of Fort Tejon, be- 

 low the yellow pine belt, it was abundant. When we ascended the western slope 

 of the Sierra Nevada from Three Rivers, we encountered the tree first below Kane 

 Flat, from which point it extended up to the yellow pines near Pig Tree Canon.
