REPORT ON THE BOTANY OF THE ADMIRALTY ISLANDS. 263 



Bryopteris fruticosa, Liiidb. et Gottsche. 



Bryopteris fruticosa, Lindb. ct Gottsche in G. L. et N. Synopsis Hepat., p. I'M. 

 Bryopteris vittata, Mitt, in Seem. Fl. Vit., p. 411. 



Admiralty Islands. 



Very large, with many elegant fronds, and with a few perfect perianths. The band of 

 enlarged cells in the middle of the leaf renders this species easily distinguishable from 

 Bryopteris sinclairii, which is in other respects very similar, and these species in their 

 perianths with three principal carinas correspond to the South American Bryopteris 

 jiiicina; but in both Bryopteris fruticosa and Bryopteris sinclairii the lateral branches are 

 much shorter, so that the outline of the frond-like principal branches is always narrower. 

 That group of species of which Ptychantkus striatus is the type differs in no other respect 

 from Bryopteris except in the more numerous folds of the perianth, and in this particular 

 is analogous to those Frullania' which have multiplicate perianths, but which on this 

 account have not been separated from that genus. 



Lejeunia sordida, Nees. 



Lejeunia sordida, Nees in G. L. et N. Synopsis Hepat., p. 367, |S. 



Admiralty Islands. — The typical plant inhabits Java, the Philippines, and the var. /3 

 is also found in the Marianne Islands. 



The perianth is elongate cylindraceous below, above the middle equally five plicate, the 

 apex obtuse ; the involucral leaves similar to the cauline. 



Frullania gaudichaudi, Nees et Mont. 



Frullania gaudichaudi, Nees el Mont ; G. L. et X., Synopsis Hepat., p. 435. 



Admiralty Islands. — Specimens bearing young perianths. This is recorded in the 

 Synopsis from Brazil, Tasmania, and Guam in the Marianne group. 



A laro-e species with the small lobule erect, close to the stem, and so placed as to appear 

 above the base of the ventral margin. Its inflorescence is probably dioecious. 



Frullania secundiflora, Mont. 



Frullania secundiflora, Mont., Syllog. Gen. el Sp. I Irypt, p. • v: ' ; ' ; - L. et X., Synopsis Bepat., p. 433. 



Admiralty Islands. — Also from the Philippines. 



In this the lobule is small, obovate, and is so much defiexed as to appear pendulous from 

 the margin of the leaf. The inflorescence is monoecious.
