The last three of these species seem usually to possess 

 a hibernating winter rosette which the first does not have, 

 though this calls for more extended observation. 



SPECIES OF MEXICO. 



In the literature at hand five species are credited to 

 Mexico: glaher Sesse & Mog., litoralis Sesse & Mog., 

 cuneifolius Fourn., CoUmensis Sesse & M09. and mollis 

 HBK. The glaher of Sesse and Mogino seems to belong 

 among some of the spicate forms. Neither litoralis, CoU- 

 mensis or cuneifolius have been recognized among material 

 at hand. The descriptions do not mention several most im- 

 portant characters. Forms of mollis apparently occur in 

 this region, as illustrated by specimens of Dr. Palmer's col- 

 lecting. More material and from type localities will readily 

 clear up the whole matter. It may be here mentioned that a 

 complete specimen suitable for study must include both 

 flowers and fruit. Specimens in our herbaria usually lack 

 good material of the former and too often of the latter. It 

 seems likely that our Carolinianus extends to Mexico and 

 may have been redescribed there, and similarly tomentosus y 

 also. 



SPECIES OF THE WEST INDIES. 



Mollis has been reported from Porto Rico, Jamaica and 

 other islands. Forms similar to our Cai'olinianus occur 

 in Cuba and Jamaica, but the material examined is scarcely 

 sufficient for definite determination. In Cuba occurs the very 

 interesting and very distinct pratensis of Wright. It is a 

 small plant as represented in our herbaria, low, the leaves 

 cauline and lanceolate, the stems slender and usually numerous
