The following synonymy and distribution brings our knowledge of this 

 species up to date. 



Leucodontopsis Floridana (Aust.) E. G. B. comb. nov. 

 Neckera {Pilotrichum?) Floridana Aust. Bot. Gaz. 4: 152. 1879. 

 Leucodoniopsis plicata R. & C. Bull. Soc. Roy. bot. Belg. 32: (i). 177. 1893. 

 Pilotrichella floridana R. & C. Rev. Bryol. 19: 11. 1893. 

 Type locality: Caloosa, Florida. 



Distribution: Grassy Key, Florida, J. K. Small 1909, no. 3227. Andros 

 and New Providence, Bahamas; Cuba, Porto Rico and Costa Rica. 



Illustrations: None, but very closely resembling Fig. 364 of L. Camerooniae 

 (Broth.) Broth, in E. & P. Pflanzenfam. fasc. 223: 753. 1905, but differing in 

 the longer more acuminate apex and the costa more clearly developed. 



Until the fruit is found, the position of this genus will remain somewhat 

 problematical, though by its leaf structure and habit it appears to be correctly 

 placed in the Leucodontaceae on account of the differentiation of the marginal 

 basal cells.

NOTES ON THE MOSSES OF JAMAICA 



Elizabeth G. Britton 



Olof Swartz in his Prodromus of the Flora of the West Indies, published in 

 1788, gave brief descriptions of 41 species of mosses, 37 of which were from 

 Jamaica, and 4 from " Hispaniola, " portions of which* he sent to J. Hedwig for 

 illustration, and 38 of these have been figured correctly either in the 3rd and 4th 

 volumes of the Descriptiones or in the Species Muscorum, in all cases from orig- 

 inal specimens collected by Swartz, so that they have become fairly well and ac- 

 curately known, under their original specific names. Having made six trips to 

 Jamaica since 1896, I have become somewhat familiar with the distribution of 

 the mosses of that island, so that it has been easy to determine the probable 

 type stations for Swartz' Jamaican species, though no localities are mentioned 

 in the original descriptions or recorded with his specimens. 



In his Symbolae ad Bryologicus Jamaicense,* Dr. Karl Miiller has rede- 

 scribed, under new names, some of these old species from collections made by 

 Mr. William Harris, principally in the Blue Mountains since 1896, in several 

 cases, probably, from the same stations where they were collected by Swartz. 

 My reasons for chis statement are, that the trails are few, they follow the easi- 

 est grades, have been long established and lead through the mountains from the 

 south to the north coast through the lowest passes. It is in these passes or 

 "Gaps" as they are called, that a wealth of mosses may be found, as the cool 

 currents of air blow through laden with moisture borne by the northeast trade- 

 winds. Morce's Gap, Portland Gap and Cuna-Cuna Gap have been highways 

 for centuries and are still delightful collecting grounds for ferns, mosses and
