 E. iiic.vicaiia Link, the chief cited specimen of which, from Lanai, has l)een kindly 

 lent to me by Dr. Diels, Director of the Botanic Garden at Berlin. The ])anicle is 

 much smaller and less develojjed than that of the specimen in the (iray Herbarium. 

 Hillebrand cites also a second specimen "Collected also by the U. S. K. Exped." 

 which evidently is the same collection as the one here made the type of E. iiiauiciisis. 

 The Ci\-:\y Herbarium s])ecimen was exaniimd by Munro and is labeled by bini 

 "P.ras^rosfis iitcxicana^ Link. H. cacnilca Hillebrand mss." "P. rocnilcscciis. 

 Hbd. in herb." is f^iven by Hillebrand as a synonym of P. iiic.vicaiia. 'Phis speci-
