4 ERYTHEA. 



of stems pubescent, upper portion, pedicels and involucres so gland- 

 ular-viscid as to catch numerous small insects; akenes pubescent on 

 the angles and somewhat so on the faces, scarcely contracted under 

 the indistinct callous ring; heads whitish and sometimes with a 

 purple tinge. 



High mountains of the Cape Region, Baja California. Perhaps 

 this variety may prove to be a distinct sj)ecies, 



Eupatorium peninsulare. Shrubby, 1-2 ra. high, glabrous; 

 leaves opposite, halberd-shaped or hastate, acuminate, more or less 

 crenate-serrate, abrupt or cuneate at bas'^ the largest 10-12 cm. 

 long, 6-7 cm. wide on petioles, 2-3 cm. long, strongly 3-nerved 

 from the base or in large leaves from some distance above the base; 

 inflorescence paniculate from the ends of the branches; bracts of 

 pedicles linear-lauceolote, 1-2 mm. long; heads 8-10 mm. long; 

 involucre spreading, in 3-4 series, about 10-flowered, the outer 

 bracts minute, ovate-obtuse, the inner 5 mm. long, narrowly ovate- 

 lanceolate, striate, scarious-margiued, longer than the akene, all 

 ciliate pubescent; akenes clavate, densely hirsute, tipped with the 

 ^-mm.-long persistent style-base; flowers tubular, styles clavate; 

 corollas pale; pappus bristles rather stout, somewhat enlarged at 

 tip, not deciduous. 



Common throughout Southern Lower California, San Jose del 

 Cabo, Sierra de la Laguna, San Francisquito, San Bartolome, 

 Canoa Hondo, San Julio, A species remarkable on account of its 

 rather broad involucral scales, hirsute akenes and cylindrical 

 flowers. 



A plant from Ojo de Agua, Comondu, which seems to belong to 

 this species, has broader involucral bracts and the leaves are occa- 

 sionally somewhat cordate. 



Erigeron Socorrensis. Sufirutescent, glabrous; leaves nar- 

 rowly oblanceolate, attenuate, tapering into a margined petiole, 

 acute, 6-8 cm. long, 6-8 mm, wide, minutely and sparsely pubes- 

 cent, crowded about the ends of the branches; heads 3-4 mm. wide, 

 corymbosely paniculate from the ends of the branches; involucres 

 somewhat inbricafced, its scales linear lanceolate; rays white, numer- 

 ous, linear, 1^ mm. long; pappus of disk flowers simple of 16-20
