3o8 Coreo-psidecB and Tagetinccr. [zoe 



The type of Vi7'eo huttoni was taken at Monterey, California, and 

 as far as I am able to judge from the description, does not materially 

 differ from the series in my possession, from San Diego and Los 

 Angeles Counties, thus leaving the Oregon form eligible to a new 

 name, for which I propose Vireo huttoni obscurus, should the above 

 differences prove as constant as I now suppose them to be.

Leptosyne heterocarpa Gray. This was originally collected 

 by Xantus near Cape St. Lucas. It has been identified with L. 

 partlmiioides both by Dr. Watson* and by myself. f In this we 

 were probably in error. There grows in the mountains of the Cape 

 Region a tall annual species, sometimes four feet high, with yellow 

 rays, dissected margins to the akenes and more dissected and con- 

 spicuously punctate foliage. It appears not to belong to low eleva- 

 tions, but occurs there in the "washes" of mountain streams. The 



J 



to the 



akenes, but they are present in specimens collected in the mount- 



ams back of Todos Santos. The species rests mainly on its size 



and on its yellow rays. The lobes of the dissected wing, both in 



this species and in L. parthenioides, are setose, especially in early 

 stages. 



L. PARTHENIOIDES is usually low or small, its rays white or tinged 

 with purple, and with purple veins. Its leaves are also punctate, 

 and It grows at low elevations as far south as the Cape. 



Leptosyne dissecta (Benth. under Acoma) is a suffrutescent 



perennial, as w^as stated in the Botany of the Sulphur.! The three 

 species must be considered as at last satisfactorily identified. 



Heterospermum and Bidens, nearly related genera, especially 

 abundant in Mexico and Baja California, are brought even nearer
