CATALOGUE OF SPECIES. 61 



Barbarea vulgaris R. Br. iu Ait. Hort. Kew. ed. 2. iv. 109 (1812). Type locality 

 European. 



Although this plant usually occurs in the United States as a weed introduced 

 from Europe, it was found in natural meadows in the high Sierra Nevada (Nob. 

 1403, 1670) in cold, wet soil, undoubtedly indigenous. 



Arabis arcuata (Nutt.) in Torr. &, Gr. Fl. i. 77 (1838), under Streptanthus; Gray, 

 Proc. Amer. Acad. vi. 187 (1864). Type locality, "shelving rocks, on high bills 

 near St. Barbara, Upper California. " 



Valley of Kaweah River (No. 13.10), and in Willow Creek Canon, Panammt Moun- 

 tains (No. 2082). Determined by Sereno Watson. No. 2082 is a form in habit closely 

 resembling A.pulchra, while its capsules resemble those of A. holbcellii. 



Arabis glabra (L.) Sp. PL ii. 666 (1753), under Turritis; Weinm. Gart. Dorp. 18 

 (1810). Type locality European. 



Valley of Kaweah River (No. 1345). Determined by Sereno Watson. This is the 

 A. perj'oliata of Lamarck. 



Arabis hirauta (L.) Sp. PI. ii. 666 (1753), under Turritis; Scop. Fl. Cam. ed. 2. 

 ii. 30 (1772). Type locality European. 



Collected in the Sierra Nevada (Nos. 1450, 2118) and White Mountains (No. 1807). 

 Determined by Sereno Watson. Dr. Watson notes No. 1450 as a "more glabrous 

 and entire-leaved form." 



Arabis lemmoni Wats. Proc. Amer. Acad. xxii. 467 (1887). Type locality, as 

 taken from Mr. Lemmon's specimen, "California." 

 Farewell Gap, Sierra Nevada (No. 1747). Determined by Sereno Watson. 



Arabis perennans Wats. Proc. Amer. Acad. xxii. 467 (1887). Type locality not 

 given; range, "from northern Nevada and Utah to Arizona and the San Bernardino 

 Mountains in California." 



Surprise Canon, Pauaniint Mountains (No. 611). Determined by Sereno Watson. 



Arabis platysperma Gray, Proc. Amer. Acad. vi. 519 (1865). Typo locality, 

 "Sierra Nevada, on Mount Dana, alt. 13,227 feet, and above Ebbett's Pass." 



In the high Sierra Nevada (Nos. 1492, 1515, 1547). Authenticated by Sereno Wat- 

 son. These specimens agree with A. platysperma in all respects except that the leaves 

 and stem are glaucous and glabrous, the ciliation of the former excepted. These 

 plants have therefore varied toward A. hoiccllii of Watson. Those that grew at 

 timber line are much more stunted than specimens from a lower altitude. 



Arabis pulchra Wats. Proc. Amer. Acad. xxii. 468 (1887)— Jones in herb. Type 

 locality, "valleys of western Nevada, to San Bernardino and San Diego Coun- 

 ties, California." 



This well-marked species was seen only in the Panamint Mountains, confined to 

 the subpinon belt of the Upper Sonoran, in Johnson Canon (Nos. 509, 591) in Sur- 

 prise Canon (No. 635), and in Willow Creek Canon (No. 778). The specimens were 

 identified by Sereno Watson. 



Arabis repanda Wats. Proc. Amer. Acad. xi. 122 (1876). Type locality, " Yosem- 

 ite Valley." 

 Near Mineral King, Sierra Nevada (No. 1389). Determined by Sereno Watson. 



Streptanthus cordatus Nutt, in Torr. & Gr. Fl. i. 77 (1838). Typo locality, "for- 

 ests of the Rocky Mountains." 

 Grapevine Mountains (No. 1765).
