Britton: West Indian mosses 655 



used by Linnaeus* and enumerated 41 species, which as at present 

 recognized belong to 37 different genera, three of these having 

 their type localities in Hispaniola (Haiti and Santo Domingo), all 

 the rest in Jamaica. 



In studying the collections made by Mr. Wm. Harris in Jamaica 

 and our own later collections, a special effort has been made to obtain 

 an accurate knowledge of these Swartz types and Dr. A. LeRoy 

 Andrews, of Cornell University, very kindly consented, when 

 he visited Stockholm in the summer of 1912, to examine these types 

 for me and compare them with specimens from our own collections 

 in Jamaica, sent as duplicates to the Naturhistoriska Riksmuseum. 

 Dr. Andrews was able to see and compare the original specimens 

 with ours in all but two cases: Br yum parasiticum Sw. [= Syr- 

 rlwpodon parasiticus (Sw.) Besch.] and Hypnum congestum Sw. 

 [= Pleuropus congestus (Sw.) Broth.], which species we have not 

 yet been able to recognize, the former being from Hispaniola and 

 the type lacking in Swartz' herbarium, the latter from Jamaica 

 and Haiti. We suspect from the illustration given by Hedwig that 

 the latter is probably referable to PalamocladiumBonplandi (Hook.) 

 Broth., which Brotherus later refers to Pleuropus, though he states 

 that he has not seen specimens of Pleuropus congestus. 



Tn 1806 Swartz discarded his Linnaean limitationsf and adopted 

 some of the generic changes proposed by Hedwig (1792), to whom 

 he sent specimens of most of his West Indian mosses, from which 

 almost all of Hedwig's plates were drawn. This eliminated 

 Fontinalis and Mnium from the West Indies and added seven 

 generaj and three species to the list given in the Prodromus; he 

 further amplified his list by giving more in detail the stations and 

 habitats. These are translated and quoted in the following list 

 of species in the sequence enumerated by Swartz, with their modern 

 names, synonyms, and distribution as at present known to us 

 from the West Indies: 



• * Fontinalis, Polytrichum, Mnium, Bryurn, and Hypnum. 

 fFl. Ind. Occ. 3: 1759-1841. 1806. 



X Encalypta, Trichostomum, Torlula, Dicranum, Plerogonium, Neckera, and 

 Leskea.
