NO. 2 GENTRY : LAND PLANTS 171 



ovate-lanceolate, the lower often broadly ovate, obtuse to acuminate, ser- 

 rulate, ciliolate, aristate, glabrous except for sparse scabrous conic scales 

 or hairs below, thinly membraneous, greener above than below; tendrils 

 1 — 2-fid; d inflorescence racemose; peduncles 10-15 cm long, glabrous 

 below the pedicles; pedicles filiform, mostly 1-2 cm long at anthesis, 

 glandular hispid; corolla shallowly campanulate, spreading, glabrous 

 without, 12-15 mm broad, the lobes subequal, ovate, obtuse, ciliolate; 

 $ flowers solitary from same axials as male ; peduncles 5-8 cm long ; ovary 

 echinate, glandular-pubescent; corolla like the cT, but smaller, about 

 1 cm broad ; fruit oblong, 2 cm or more long, glabrate, glandular pubes- 

 cent, echinate throughout with slender prickles 8-12 mm long, narrowly 

 beaked, 1 cm long. 



Taxonomists have assigned earlier collections of this well marked 

 species to either E. toquata D.C., an uncertain species from the Mexi- 

 can mainland (Rose, C.N.H. 5:118 ) or to E. minimus^ well known on 

 the peninsula. The proposed new species is distinguished from the latter 

 by the deeply lobed leaves, the hyalinely tufted nodes, the long cf pedun- 

 cles, the larger flowers, and the larger, longer-prickled fruits. The range 

 of the species appears to be restricted to the southern part of the peninsula, 

 and is perhaps a postinsular endemic of the Cape District. Besides the 

 type collection, the following specimens have been reviewed in the Uni- 

 versity of California Herbarium: San Jose del Cabo, Brandegee sine no, 

 in October 1902; Brandegee 231, September 27, 1890; Brandegee sine 

 no., September 18, 1893 ; La Mesa, Brandegee sine no., October 24, 1893.

Ensenada de los Muertos, Cape District, March 5, Rempel 78, hill- 

 side. 



This vine is rare in herbaria. It is known only from the Cape Dis- 

 trict; type from La Paz. It is the basis of Cogniaux's section, Pseudo- 

 Echinopepon, (1. c), characterized by the globose, 1-2 seeded, echinate, 

 long-beaked fruits, features embodied in the genus Vaseyanthus. 



Vaseyanthus Palmeri (Wats.) Gentry new comb. 



Echinopepon Palmeri Wats., Proc. Am. Acad. Sci. 24:52. 1889. 



Brandegea Palmeri (Wats.) Rose, C.N.H. 5:120. 1897. 



San Carlos Bay, February 8, Dawson 1073. 



Known only from Guaymas and vicinity where it has been but rarely 

 collected. It is probably to be grouped with those plants having insular 

 origin in the cerros northwest of Guaymas. It is related to V. insularis.
