CATAtOGUE OF SPECIES. 133 



Hemizonia pungens (Hook. & Arn.) Bot. Beech. 357 (1840-11), under Harlmannia; 

 Torr. & Gr. El. ii. 399 (1843). Type locality not given. The original specimens 

 were collected in California by Douglas, 



Near Title River, in the Tulare Plains (No, 1250). 



Hemizonia wheeleri Gray, Bot. Cal. 1.617(1876). Type locality "Tulare Co., 

 Monachay Meadows, etc., upper part of South Fork of Kern River, at 8,200 to 10,000 

 feet altitude," California. 



The type specimen belongs to No. 306 of Rothrock's Wheeler Survey collection, 

 but No. 335 of the same collection has also been referred here. In the latter plant 

 the anthodia are arranged in close cymes at the ends of the branches, while in the 

 former the anthodia are single upon scattered peduncles. Our No. 1395 is identical 

 with Rothrock's No. 306, andNos. 2121,2134, and 2136 with his No. 335. The characters 

 of the flowers and achenia, as well as pubescence, are the same in both forms. The 

 bracts of the outer chaff of the receptacle are not distinct, as originally described 

 and figurefl, but connate for about half their length. All the specimens were col. 

 lected in the high Sierra Nevada. 



Lagophylla ramosissima Nutt. Trans. Amer. Phil. Soo. new ser. vii. 390 (1841). 

 Type locality, "in the prairies near Walla-Walla, in Oregon." 

 Between Kernville and Havilah (No. 1053). 



Layia gland'ulosa (Hook.) Fl. Bor. Amer. i. 316 (1834), under Blepharipappus; 

 Hook. & Arn. Bot. Beech. 358 (1840-41). Type locality, "on the plains of the Colum- 

 bia, in sandy soils, under the shade of Purshi-i and Artemisia." 



Shepherd Canon, Argus Mountains (No. 738). It should be noted that the priority 

 of this genus over the leguminous Lai/ia of Hooker and Arnott rests upon the state- 

 ment : 1 "If this were to form a new genus we would propose the name of Lat/ia, after 

 one of the discoverers," followed by a generic diagnosis separating it from Tridax. 

 Subsequently in the same work- the leguminous genus Layia, afterward referred to 

 Ormosia, was published, but l)e Candolle 3 considered the first mention sufficient to 

 constitute publication, and adopted the name for the genus of Composite. 



Perityle emoryi nuda (Torr.) Pac. R. Rep. iv. 100 (1857), as V. nuda; Gray, Bot. 

 Cal. i. 397 (1876). Type locality "arroyos and canons at Williams' river, and on hills 

 near the Colorado of the West." 



Determinations authenticated by J. N. Rose. This plant occurred in the Larrea 

 belt in a canon of the Funeral Mountains, west of Ainargo*a (No. 324) ; between Ash 

 Meadows and Furnace Creek Ranch (No. 437); in Johnson (No. 546), Hall (No. 699), 

 and Surprise canons, Panamint Mountains; and in Panamint Valley (No. 669). 



Baileya multiradiata Harv. &. Gr. in Emory, Rep. 144 (1848). Typo locality, 

 "along the Del Norte and in the dividing region between the wators of the Del Norte 

 and those of the Gila." 



Near Winters's ranch, Pahrump Valley, Nevada (No. 296). 



Baileya multiradiata pleniradiata (Harv. & Gr.) in Gray, PL Fendl. 105 (1849), 

 as B. pleniradiata. Typo locality, "California." 



Between Darwin and Keeler (No. 945). 



The original />. multiradiata of Emory's Report is the long-peduncled broad-headed 

 form called variety nudicaulix in Gray's Synoptical Flora, while the B. multiradiata 

 of the latter work is the B. pleniradiata of the Plantse Fendlcriame. 



Psilostrophe cooperi (Cray) Proe. Amer. Acad. vii. 358 (1868), under llidddlia; 

 Greene, Pittonia, ii. 176 (1891). Type localities, "gravelly banks at Fort Mohave," 

 "on the Colorado," and "Camp Grant, &c, Arizona." 



iHook. & Arn. Bot. Beech. 148 (1833). 3 Prodr. vii. 294 (1839).
