Pectis papposa, Gray. — San Gregorio. 



Pectis canescens, HBK. Probably a form of this poly- 

 morphus species. The plants are only a few inches high, 

 glabrous, with long-pecluncled heads and few setas on the 

 leaves, which have large sparse marginal glands. The 

 pappus is multisetulose in the disk, 2-auriculate setose in 

 the ray. — Comondu, Purisima. 



Pectis multiseta, Benth. — San Gregorio, San Jorge. 



CoTULA coRONOPiroLiA, L. — Socorro. 



Artemisia Californica, Less. — Las Huevitas. 



Artemisia, sp. Neither flowers nor fruit could be found. 

 Perhaps a form of A. Ludoviciana. — San Pablo. 



Peucephyllum Schottii, Gray. — Calaraujuet. 



Psathyrotes ramosissima, Gray. — Agua Dulce. 



Lepidospartum squamatum, Gray. — El Campo Aleman. 



Berbia juncea (Benth.) The leaves of these specimens 

 from the original locality are all entire, the outer series of 

 involucral scales broadly ovate and not acuminate, and the 

 pappus nearly equals the flowers. — Magdalena Island. 



Bebbia atriplicifolia (Gray.) An extreme form has 

 leaves 2 inches long by IJ wide, the flowers usually 

 somewhat surpassing the pappus, and the involucral scales- 

 oblong and often acuminate. Between this and B. juncea 

 of Magdalena numerous connecting forms are found, and, 

 as Dr. Gray has written, there is probably but one species. 

 — San Gregorio, Comondu. 



Senecio Douglasii, DC. — Agua Dulce. 



Senecio Lemmoni, Gray. A form with narrow linear 

 leaves, more wooly in the axils. — San Esteban. 



Cnicus Neo-Mexicanus, Gray. — San Sebastian. 

 Cnicus, sp. Eight feet high, flowers purple, bracts fim- 

 briate. — Common along the banks of Comondu Creek.
