 Cent. Am., vol. Ill, p. 602. 



This well-marked species was rather common among ex- 

 posed roots of trees along the rock}* banks of a small stream 

 in the deep woods, near Castillo. The fronds are mostly 

 proliferous. It has not been reported from Nicaragua.

 and Bak., Syn. Fil., p. 73. 



This interesting species was quite common on the wet clay- 

 banks along a small stream in the deep woods near Castillo. 

 In general appearance and habit it resembles the thallus of 

 some of the larger liverworts, the fronds lying flat on the 

 mud, over the surface of which the slender hairy rootstocks 

 creep. None were found in other situations. The variation 

 in the form and division of the frond is shown by Figs. 2 and 



3. Plate 1. 



It is not reported in the Biol. Cent. Am., and seems not to 

 have been found heretofore in the Central American region. 



3. T. punctatum Pair. 1 PI. 1. Figs. 4-1 1. 



Hook, et Grew, Icon. Fil., pi. ccxxxvi; Hook., Sp. Fil., vol. 1, p. 116; Hook, 

 and Bak., Syn. Fil., p. 74; Hemsl., Biol. Cent. Am., vol. Ill, p. 602. 



T. reptans Swartz, — Hook, et Grew, Icon. Fil., pi. xxxii; Hook., Sp. Fil., 

 vol. 1, p. 116: Hook, and Pak., Syn. Fil.. p. 74; Hemsl., Biol. Cent. Am., 

 vol. in, p. 603. 



There seems to be no good reason for separating T. -punc- 

 tatum from T. reptans. The descriptions of the two forms 

 in Hook, and Bak. Syn., Fil.. show practically no difference. 



Hooker, in Spec. Fil., vol. 1. p. 116. says that T. reptans is 



1 The author has had some trouble in determining which of the two 

 names T. punctata 01 and T. reptans has precedence as neitherof the original 

 descriptions was at hand. As nearly as could be determined, however, 

 from Jackson's " Guide to the Literature of Botany," Poiret's name is the 

 earlier one. If this is an error the synonymy should be reversed.
