A. West INDIAN MOSSES KNOWN TO LINNAEUS 
In Linnaeus’ Species Plantarum* 8 generat and 103 species of 
mosses are recognized, of which only 2 are known to be tropical 
American in their distribution, ranging from southern Florida to 
South America. The first of these tropical species is Bryum albi- 
dum L. (p. 1118) known to Dilleniust as Bryum nanum, lariginis 
foliis albis, and now known as Octoblepharum albidum (L.) Hedw., 
with the type locality on the island of New Providence in the 
Bahamas. 
The other species, Rhizogonium spiniforme (L.) Bruch was 
the first species of Hypnum named by Linnaeus and it also was 
based on a Dillenian description and plate.§ He called it ‘the 
Herring’ s-Bone Hypnum” and his specimens were sent to him from 
Mt. Diabolo, Jamaica, by Sir Hans Sloane. Its range through 
the tropics is even wider than that of Octoblepharum, including the 
Islands of the Pacific; both species are known to occur not only 
throughout the American tropics but also in Asia and Africa.
