Jennings: Contribution to Botany of Isle of Pines. 107 



Northern part of the island, Blain, Nos. 17, 20, 40, 181. (Mills- 

 paugh). General Distribution: Cuba, Isle of Pines, Jamaica, and in 

 continental tropical America. 



In view of the close relationship of the species, and the fact that 

 Plain's collections and those of the writer were made in the same 

 locality, the writer is inclined to believe that Plain's specimens belong 

 to the following species: 



236. Piper angustifolium var. Ossanum DeCandolle. 



Piper angustifolium var. Ossanum DeCandolle, Prodromus Systematis Naturalis 

 Regni V'egetabilis, XVI, (i), 1869, p. 286. 



Collected but once, in thicket at side of a pool near the base of 

 Caballos Mts., east of Nueva Gerona, May 9, 1910, 0. E. Jennings, 

 No. 168. General Distribution: Cuba, the Isle of Pines, and Mexico. 



Although first identified with Piper elo?igatum the specimen is 

 certainly not of that species. The specimen has rather densely vil- 

 lous branches, the leaves are rather densely and more or less ap- 

 pressed-villous below, eventually smoothish but minutely scabrous 

 above, there are four stamens, the bracts being villous above, and the 

 ovary is sub-tetragonal, almost three-angled, and at first hirtellous 

 on the top. The leaves reach a length of about 16 cm. and a width 

 of 5 cm., and when mature become sub-lustrous above. 



After an examination of specimens in the herbarium, it becomes 

 plainly evident that many of the narrower-leaved specimens from 

 Cuba and Mexico belonging to this species have been erroneously 

 labeled "Piper adunciim L."
