CATALOGUE OF SPECIES. 221 



2,970 meters, accompanied by P.flexilis, P.ponderosa, Abies concolor, &m\ Junipcrus ocei- 

 dentalis monospermy but higher up in the thickest part of its belt the only other 

 tree was P. flexiUs. On the Panaraint Mountains (No. 537) the tree was seen at the 

 altitudes of from 2,770 meters, on a north slope, to 3,060 meters, and undoubtedly con- 

 tinues to the summit of Telescope Peak, 3,333 meters high. Like all the other trees 

 on the highest part of this range, P. aristata grows not in a solid forest, but its 

 individuals widely scattered. In none of the other mountains east of the Sierra 

 Nevada, carefully explored by the expedition, did the bristle-cone pine occur, except, 

 perhaps, the Inyo Range. All the cones that came from these mountains, collected 

 by Mr. Nelson and Mr. Funston, were lost in transportation, but the tree has been 

 reported heretofore from this range. 



Pinus attenuata Lcmmon, Gard. &. For. v. G5 (1892). Type locality, 1 "to the 

 south of Monterey [California], in hit. 36°, near the level of the sea, and growing 

 almost close to the beach." 



The narrow-cone pine that has long been known by Gordon's name, P. tuberculata. 

 It did not occur properly within the range of expedition's work, but a specimen 

 (No. 1862) was brought by Mr. Nelson from the vicinity of the Yosemite Valley. 



Pinus albicaulis Engelm. Trans. St. Louis Acad. ii. 209 (1863). Type locality, 

 " Cascade Mountains, in Oregon." 



Specimens of the alpine white-bark pine wore collected in the Sierra Nevada, at 

 Kearsage Pass (No. 1860), and on a peak near Mount Whitney (Nos. 2076, 2077). The 

 tree did not occur in any of the desert ranges, and although careful search was made at 

 timber-line in three directions from Mineral King, on the western crest of the Sierra 

 Nevada, and along the northeast side of Whitney Meadows, on the eastern crest, the 

 tree was not found. It is probable that Mount Whitney marks its southern limit in 

 tins Sierra Nevada. Mr. Bailey, who collected the specimens from that vicinity, says 

 that the individuals varied in size and form from trees 12 meters in height to low, 

 prostrate shrubs, and that the species constituted the real timber- line tree of the 

 locality, ranging 30 meters higher than P. balfotuiana, and extending to an altitude 

 about 200 meters below timber-line. 



Pinus balfouriana Jeffr. Rep. Oreg. Exped. (1853). 



On the high peaks and crests of the Sierra Nevada, about Mineral King (No- 

 1417) the foxtail pine is the tree that stands next below timber-line. The slopes 

 here are so steep and rocky that solid forests cannot exist, but all about Whitney 

 Meadows and up to timber-line on the adjacent peaks the tree is very abundant, at 

 the lower part of its belt growing freely intermixed with P. murrayana. It is rarely 

 reduced at timber-line to a depressed shrub. Specimens were collected at Kear- 

 sarge Pass (No. 1861). 



Pinus flexilis James, Long Exped. ii. 35 (1823). Type locality, "arid plains sub- 

 jacent to the Rocky Mountains, and * * * up their sides to the region of per- 

 petual frost." 



This, the Rocky Mountain white pine, was found on the Charleston Mountains (No. 

 316), growing with P. aristata, but not so abundant as that species. On the Pana- 

 mint Mountains (No. 538) it occurred in the same position. Mr. Funston collected 

 specimens on the highest peak of the Grapevine Mountains (No. 1767). In the 

 Sierra Nevada a few specimens were observed along the Hockett Trail, in the valley 

 of Little Cottonwood Creek, on the eastern slope of the Sierra Nevada (No. 1866). 

 It has been reported also from Mount Silliman and from the Inyo Mountains. 



Pinus flexilis macrocarpa Engelm. in Eothr. Bot. Wheeler Surv. 258 (1878). 

 Type locality, "on the San Francisco Mountains," Arizona. 



This tree "is known only in San Francisco Mountain, Arizona (No. 1), where it 

 was collected by the writer on his way to California. It does not properly come 



within the range of the present report.
