402 A. W. JEvans — Hawaiian Hepaticm of the Tribe JubuloidecB. 



The cell-structure of F. aplculata has already been figured by 

 Schitfner,* who gives numerous interesting details about it. The 

 inflorescence seems to be variable. All the fertile specimens from 

 the Hawaiian Islands which I have seen are autoicous, while a Javan 

 specimen kindly sent me by Herr Stephani, bears antheridia only. 

 According to Gottsche,f the var. a of the Synopsis is monoicous, 

 while the var. /3 is dioicous. 



Frallania apiculata is a species which is intermediate between the 

 subgenera Thyopsiella and Diastoloha of Spruce, and might be 

 placed in the former perhaps better than in the latter. One of its 

 closest allies, however, is Fnillania exilis Tayl., of South America, 

 and, as Spruce himself refers this species to Diastoloha (probably 

 on account of its autoicous inflorescence), I have referred F. apicu- 

 lata to the same subgenus. The South American species is much 

 smaller in all its parts than F apiculata, its leaf -lobes are very 

 abruptly and minutely apiculate, its lobules are more slender, and 

 the divisions of its bracts are more abruptly acuminate. 



Of F. oceanica Mitt., the author has kindh^ sent me an authentic 

 specimen from the island of Tahiti, which agrees very closely with 

 the Hawaiian specimens above described. A second species of the 

 Pacific islands, F. Pacifica Tayl., seems to be very close to F. apicu- 

 lata, but is described as having subdentate bracts.

Autoicous : plants closely appressed to substratum, scattered or 

 forming thin patches of considerable extent, dark red or purple, 

 often almost black : stems, at least when young, regularly pinnate 

 or bipinnate : leaves somewhat imbricated, the lobe ovate, arching 

 over the stem but not cordate at base, slightly decurved at the 

 rounded apex, convex, entire ; lobule clavate, close to axis and i)ar- 

 allel with it, rounded at base, inflated throughout ; stylus minute, 

 filiform, consisting of three or four cells in a single row: underleaves 

 distant, obovate, cuneate and not at all cordate at base, bifid about
