CATALOGUE OF SPECIES. 81 



Acer glabrum Torr. Ann. Lye. N. Y. ii. 172 (1828). Type locality, "on the 

 Rocky Mountains." 



This maple, wherever found, attained only the dimensions of a shrub 2 meters high 

 or less. It was collected in the Grapevine Mountains, east of Death Valley (No. 

 1757), and in Death Valley Canon, Panamint Mountains (No. 2018), at an altitude, 

 in both places, of between 6,000 and 7,000 feet. 



Acer macrophyllum Pursh, Fl. i. 267 (1811). Type locality, " on the great rapids 

 of the Columbia river." 



In the Tejon Mountains (No. 1160). 



Acer neguiido L. Sp. PI. ii. 1056 (1753). Type locality, "in Virginia." 

 The box elder of the coast region of California, considered by some a variety of 

 Actr negundo, by others a distinct species, A. californicum, has its twigs, petioles, 

 leaves, peduncles, and capsules tomentose. Our tree, from Canada de las Uvas (No. 

 1164), which is the same as No. 264 of the Wheeler Survey, and was collected in the 

 same locality, has these parts, with the exception of the slightly hairy lower surface 

 of the leaves, entirely glabrous, in this respect resembling the box elder of the Atlan- 

 tic States, and differing not only from the California coast tree, but from the usually 

 tomentose form characteristic of the Great Plains and Great Basin. Dr. Merriam 

 reported the tree in the Santa Clara Valley, Utah. 



ANACARDIACE.5J. 



Rhus diversiloba Torr. & Gr. Fl. i. 218 (1838). Type locality, "borders of 

 woods &c, Oregon & California." 



This, the common western poison ivy, was found at several points on rocky hill- 

 sides in the foothill bolt of the western slope of the Sierra Nevada, throughout the 

 part of it that we traversed. 



Rhus ovata Wats. Proc. Amer. Acad. xx. 358 (1885). Typo locality, " on hills 

 and mountains, away from the coast, from San Diego to Los Angeles County," etc. 



Near San Bernardino (No. 110). The type specimens of lihus (Styphonia) integrifolia 

 were collected ' on the margins of cliffs, &c, near the sea, around St. Diego & 

 St. Barbara," California. Bhus ovata, as indicated by the type locality given above, 

 is an inland species. Dr. Watson says (loc. cit.): "It has been confounded with the 

 coast species B. integrifolia (and figured for it by Torrey in Pac. K, Rep. 7. 9, t. 2, 

 excepting the single leaf), which has smaller obtuse and more frequently serrate 

 leaves with shorter petioles, more pubescent, and with twice longer fruit (5 lines in 

 diameter)." 



Rhus trilobata Nutt. in Torr. & Gr. Fl. i. 219 (1838). Type locality, "in the 

 central chain of the Rocky Mountains." 



Observed at the summit of Cajon Pass; near Mountain Springs, Charleston Moun- 

 tains; in Vegas Valley, near Vegas Ranch; in Johnson (No. 659) and Surprise (No. 

 618) canons, Panamint Mountains; and between Ilavilah and Calicnte ; andreported 

 by Dr. Merriam from the Pahranagat Mountains of Nevada and the Beaverdam 

 Mountains of Utah. 



LEGUMINOSiE. 



Lupinus argenteus decumbens (Torr.) Ann. Lye. N. Y. ii. 191 (1828), as L. 

 decumbens ; Wats. Proc. Amer. Acad. viii. 532 (1873). Type locality, "on the south- 

 ern branches of the Ark ansa." , 



Near Mineral King, Sierra Nevada (No. 1478). The pubescence is more pro- 

 nouncedly hirsute than is usual. Determined by E. L. Greene. 



Lupinus brevicaulis Wats. Bot. King Surv. 53 (1871). Type locality, "in 

 the valleys and lower canons of Western Nevada to the East Humboldt Mountains," 

 etc., at "5,000 to 8,000 feet altitude."
