Island of Porto Rico, while it is frequently, more or less, fusiform, it is also 

 at times, quite cylindrical. An unpublished picture by Krug in the Her- 

 barium at Berlin shows it thus. 



I do not think the name of A. fusiformis at all applicable to the plant of 

 Cuba, which has the trunk almost smooth, th« spines being detachable and 

 deciduous; while the spinescence described by Swartz for his C. fusiformis is 

 exactly the same as that which covers the trunk of C. aculeata. 



The fruit described by Swartz as that of his A. fusiformis (drupa .... 

 oblonga) is certainly that of a quite different plant, and is, very probably, as 

 supposed by Martins, the fruit of Syagrus (Khyticocos) amara. 



To be enabled to decide on the right names to be assigned to each of 

 the two species of Acrocom.ia of the Antilles I have passed in review all the 

 kno\vn species referable to that genus, and I have been able to recognize that, 

 altliough all the Acrocomia are v«ry similar in general aspect, they nevertheless 

 offer good diagnostic characters in their flowers, l)oth male and female, by 

 which the species may be easily distinguished.
