4- Acoelorhaphc Wendl. This generic name, published without 

 a type in 1879, and therefore a hyponym, must give way to the 

 generic name Pmirotis Cook, Mem. Torrey Club 12 : 21. 1902, 

 not mentioned by Professor Beccari. He recognizes two species, 

 one from Cuba, the other from Florida, which do not seem to us 

 to be distinct, and his descriptions call only for differences in the 

 foliage. The genus is made up of the following elements : {a) 

 Copcrnicia Wrightii Griseb. & Wendl., from Cuba ; (b) Scrcnoa 

 arboresccns Sarg., from Florida ; and (c) Paiirotis androsana Cook, 

 from the Bahamas. In my opinion these represent but one 

 species, and the oldest name for it is Wrightii. 



5. Erythea S. Wats. Four species are recognized from north- 

 ern Mexico and Lower California. 



6. Copernicia Mart. Nine species are recognized, five of them 

 from South America and four from Cuba, including a proposed 

 C. Ciirtissii from the Isle of Pines, which differs very slightly 

 from the well-known C. hospita Mart. In this connection it is to 

 be hoped that some light maybe thrown on the record by Grise- 

 bach for the island of Jamaica of Copcrnicia tcctoruni Mart., 

 otherwise known only from Venezuela, though erroneously 

 attributed by Grisebach to Hayti, Careful search in Jamaica by 

 Mr. Harris and by me has hitherto failed to reveal the presence 

 there of any species of this genus, though it is possible that one 

 may yet be found there. Professor Beccari evidently did not 

 completely understand Dr. Morong's descriptions of Copernicia 

 alba and Copernicia rubra from Paraguay, in Ann. N. Y. Acad. 

 Sci. 7 : 245, or he might have used one of these names for the 

 plant he proposes as C. aiistralis, even if they are not specifically 

 distinct. 



7. Washingtonia Wendl. In this genus of southern California, 

 Lower California, and Sonora, the three previously published 

 species are recognized, together with two additional varieties, 

 although he regards W. Sonorae as dubious and to be compared 

 wath W. robusta. He does not cite the equivalent names under 

 Neoiuashingtonia, proposed some years ago by Mr. Sudworth, 

 and makes no mention of Was/iingto7iiaWend\. being a homonym ; 

 it is a homonym, however, and a revertible one.
