160  LEJEUNEAE OF THE UNITED STATES AND CANADA 
Mountains, those in the Taylor herbarium could not have come 
from Ohio. | 
All of these specimens from the Alleghany Mountains are per- " 
fectly sterile and many different conclusions have been drawn from 
them. As we have already seen they were referred by Sullivant E 
to Z. cucullata Nees and by Taylor to his Z. lucens. Spruce - 
thought at first that they were the same as the Mexican L. diversi- ۲ 
folia Gottsche * and afterwards transferred them to his Z. diversi — 
loba.t Still later he referred them with some hesitation to L. 
lucens.{ Carrington suggested that they were probably the same 
as L. crenulifolia Gottsche Ms. from the island of Trinidad.$ | 
If these specimens, which are so doubtful, are to be regarded - 
as the type-specimens, the species is certainly unfortunate. Spruce, i 
however, considered that the type of Lejeunea lucens was a speci- ۱ 
men which Taylor had deposited in the Kew herbarium. || This > 
specimen came from Brazil and was labeled: “Pará, in cortice — 
(T. L. R.) in Herb. Hook.” In his original description Taylor — 
states that his specimens came from the Hooker herbarium, and 
this fact would of course Support Spruce’s view. Spruce was able 
to identify with this Kew specimen a fertile plant which he himself a : 
had collected near Para and in this way gave the species a firm | 
footing. The specimens from Florida and Louisiana agreeing — 
closely with this South American plant, perhaps it would be wisest 
to follow Spruce and consider the Para plant at Kew as the type — 
of Microlejeunca lucens. We can then refer tentatively to this ۱ 
species the doubtful Alleghany Mountain specimens, until some- — 
thing more definite is learned about them. = 
The generic position of the present species is not altogether ， 
definite. By Spruce it was first placed in the subgenus Miete co
