Margarita and Magdalena Islands. The akenes of this 

 variety have thin margins, the rays are white, the pappus 

 consists of a slight but evident crown, with occasionally a 

 single, slender, retrorsely-hispid awn. Whether this form 

 can be kept in the species admits of a doubt; but there can 

 be none in the case of LajjJiamia peninsular is, which, de- 

 scribed from mere fragments in the Herbarium of the Cali- 

 fornia Academy of Sciences, has now been again collected 

 at Purisima and Comondu, and agrees with the original 

 description of P. Fitcliii — " Branches of the style tipped 

 with slender and acute, but rather short, appendages. 

 Achenia compressed, usually with two approximate nerves 

 at each margin, which are barely hirsute, terminated by a 

 small disk-shaped rather prominent areola, which is en- 

 tirely naked, there being no trace of a pappus." (P. R. R. 

 Rep. iv, 100) — better than any other specimens seen. 



From the notes here given it would seem possible to 

 separate at least one species, but gradations occur, and 

 forms found at San Gregorio are almost exactly intermediate. 

 It is probable that the range of variation of the species in 

 this genus has been much underestimated. 



Ba:RiA GRACILIS, Gray. — El Rancho Yiejo. 



B^RIA, sp., a very small species. — Socorro. 



Eriophyllum lanosum, Gray. — San Luis, Agua Dulce and 

 San Sebastian. The form found at the latter place has the 

 palege and awns of nearly the same length and barely dis- 

 tinguishable. 



Amblyopappus pusillus, Hook & Arn. — From San Enrique 

 across the Peninsula to San Quintin. 



Palafoxia arenaria. Perennial, decumbent, fleshy, much 

 branched from an indurated base, branches divaricate, 

 spreading, a foot or more long, pubescent and glandular: 

 leaves densely strigose-pubescent on both sides, linear, 

 obtuse |-1^ inches long, 3-6 mm. wide, narrowed at base
