Hawaii: Kilavea (Didrichsen). East Maui (Baldwin). Oahu: 
Konahuanui (Heller, Cooke) ; Lanahuli (Cooke). 
This species is very common on the higher mountain ridges, where 
it completely covers the trunks, branches and twigs of the lower 
stunted trees, sometimes along with Herpocladium and Herberta, 
which it closely resembles to the naked eye. Of the Hawaiian 
Bazzanie, B. Dideriaciana is nearest to B. emarginata. ‘The stems 
of the latter are much longer and slenderer, the leaves are usually 
distant, are longer, narrower and more falcate, the apex is bidentate, 
the underleaves are smaller and narrower in proportion to their 
length, the leaf-cells are much larger. 
B. emarginata is very close to B. fallax (Sande-Lac.) Schiffn., of 
the East Indian archipelago. Unfortunately the writer has been 
unable to procure specimens of the latter species. The comparisons 
are therefore made from the descriptions and figures.’ The Hawaiian 
species differs from the East Indian in the following characters : the 
leaves are longer and narrower, with much longer and more subulate 
teeth, the underleaves are much shorter and broader, the leaf-cells 
are somewhat larger, the innermost bracts are longer, narrower and 
with much fewer and shorter lobes.

PuatTE V; FIGURES 14-33. 
Plants loosely cxspitose, yellowish green: stems slender, sparingly 
branched, sometimes with leafy branches given off from axils of 
underleaves, oval in section ; flagella few, scattered, very slender : 
leaves distant, approximate or imbricated at the base, subfalcate, 
when dry concave, sublanceolate to obliquely ovate, antical base 
curved, arching nearly over the stem, postical base not decurrent, 
obliquely truncate, tri-(bi-)dentate, antical tooth the largest, 3 to 
6 cells long, 2 to 4 cells broad, median and postical teeth usually 
containing from 3 to 5 cells; sinuses obtuse or lunate : underleayes 
remote, wider than stem, ovate-quadrate, apex truncate, undulate or 
erose-dentate, with obtuse teeth: leaf-cells at apex thin-walled,

1874. This species is referred by Schiffner to B. fallax (vid. Conspectus Hepati- 
carum Archipelagi Indici, 158, 1898).
