of the Tribe Trigonanthee. 9 
similar to bracts; bracts of second row similar to innermost bracts 
but smaller; bracteole similar to bracts of second row; perianth 
broadly fusiform, terete below, many keeled above, mouth slightly 
contracted, irregularly lobed, lobes laciniate, laciniz 4 to 6 cells long, 
2 to 4 cells broad, cells of laciniw slightly verruculose: ¢ spike 
usually occupying a short postical branch, rarely terminal on a 
lateral branch ; bracts in 4 to 8 pairs, imbricated, concave or sub- 
complicate, broadly ovate, unequally bifid about two-thirds or one- 
half; lobes irregularly dentate, subulate, spreading, 3 or 4 cells broad 
at base, 6 or 7 cells long, ending in a row of about 3 cells, the apical 
cell slightly verruculose, the postical lobe broader than the antical ; 
bracteoles similar to the stem-underleaves : capsule oval, dark brown ; 
elaters blunt, bispiral. 
Stems 0.07"™ in diameter ; leaves 0.13"™ long x 0.05™™ broad at 
base ; leaf-cells of lobes 23ux16p, at base of leaf 18u4x1l4y3; inner- 
most bracts 0.7™™x0.4™"; perianth 0.9™™ to 1.7™™x0.4™™ to 0.5™™ ; 
spores 12 in diameter ; elaters 150ux12u; ¢ bracts 0.22™™x0,15™™. 
West Maui (Baldwin). Oahu: Nuuanu (Cooke). 
This species is abundant in the latter locality, growing on the 
ground or fallen logs, on the shady lateral ridges. 
Lepidozia setacea (Web.) Mitt. is very close to this species. For 
comparison specimens from G. & R., Hep. Eur., No. 502, were used. 
The Hawaiian species has leaves which are usually 3—parted, while 
in the European species the leaves are usually 4-parted; in the 
Hawaiian species the lobes are never 2 or 3 cells broad for 3 or 4 
rows, but are shorter and narrower than the lobes of Z. setacea; 
the leaf-cells have slightly thinner cell-walls and the terminal cell is 
not verruculose as in the European species ; the underleaves of the 
Hawaiian species are usually bipartite, while in the European species 
they are usually tripartite ; the leaves subtending branches in JZ. 
Hawaica are made up of a single row of cells, while in Z. setaceu 
these leaves are bipartite ; the perianth of the Hawaiian species is 
smaller, and the innermost bracts and bracteoles are smaller and not 
so deeply lobed. 
Acromastigum Evans, 1900. 
Plants medium-sized, scattered among other hepatics, yellowish 
green, becoming brownish with age: stems stiff and wiry, mostly 
ascending or erect, sparingly branched: vegetative branches of 
three kinds: terminal branches from the lateral segments, terminal 
branches from the postical segments (flagella), intercalary branches
