 edge, otherwise entire or slightly angular-sinuate near the base ; 

 bracteole ovate, bifid about two fifths with acuminate lobes and 

 narrow sinus, margins entire or nearly so; perianth about two fifths

 arranged in small circular patches.

On rocks and trees. Hawaii (Beechey, Macrae). Oahu : Lulumahu 

 and Nuuanu (Cooke); also collected by Mann and Brigham, West 

 Maui (Baldwin). Hawaiian Islands (Gaudiphaud, Hillebrand). The 

 species is widel}^ distributed in the Malayan Archipelago, in southern 

 Africa, and among the islands of the Pacific. 



As Schiffner* has lately pointed out, the original description of 

 Frullania apiculata states that the perichsetial bracts and bracteoles 

 are incised-serrate. The authors of the Synopsis Ilepaticarum, how- 

 ever, applied the name to a plant with entire bracts and bracteoles 

 and all subsequent authors have done the same thing. If the type- 

 specimens in the Nees Herbarium should turn out to be pure Frul- 

 lania serrata Gottsche, as Schiffner thinks probable, then the name 

 of this species should be changed to F. apiculata, and the plant 

 which is at present known by this name should be called something 

 else. Herr Stephani writes me that the Frullania explicata of Mon- 

 tague, of which he has seen the original specimens, is the same as the 

 F. apiculata of the Synopsis; and, therefore, if any change of names 

 becomes necessary, the plant with entire bracts and bracteoles should 

 be called F. explicata Mont. It is quite possible, however, that the 

 two species are mixed in the type-material, in which case of course 

 no change would be required.
