PLANTS FROM BAJA CALIFORNIA. 177 



specimens seen without awns. The plant agrees exactly 

 with Bentham's figure but is usually much larger, and so 

 far from being referable to L. partlienioides finds its closest 

 and perhaps too near relation in L. Arizonica. — Magdalena 

 Island. 



Leptosyne Douglasii DC. — San Enrique. 



Hemizonia fasciculata T. & G. — Las Huevitas. 



Layia heteroteicha Hook. & Arn. — San Enrique. 



Layia platyglossa Gray. — El Rosario. 



Layia glandulosa Hook. & Arn. — San Quintin. 



Jaumea caknosa Gray. — San Quintin. 



Riddellia Cooperi Gray. — San Luis, San Sebastian, Agua 

 Dulce. 



Baileya multiradiata Harv. & Gray. — Agua Dulce. 



Perityle deltoidea Watson. Probably this species, but 

 the awn often wanting. — Common on Magdalena Island and 

 about Comondu. 



Perityle Palmeri Watson. Plants larger in every way- 

 than the Guaymas specimens: leaves thin, nearly glabrous; 

 akenes compressed below the summit, with a stout subulate 

 awn. — Common on the cliffs at Comondu and Purisima. 



Perityle Californica Benth.— The plants which answer 

 to Bentham's description and come from the same locality, 

 have, as he says, yellow rays, "ex sicco flavf© videnter," 

 and akenes either hispid or smooth in the same head, with 

 a callous margin, a crown of lacerate squamellse, and the 

 awn, though usually present; often wanting. — Magdalena 

 Island. 



Perityle Fitchii Torr. This species seems to be consid- 

 erably confused. Dr. Gray included in it var. Pahneri from 

 Guadalupe Island, and also growing abundantly about Santa 



2d See., Vol. II. ( 13 ) December 5, 1889.
