apex, teeth (usually 4) composed of 2 to 4 cells, rounded or acute, 
terminal cells verruculose ; sinuses separating teeth lunate ; cells near 
middle of bract oblong, with uniformly thickened walls ; bracteole 
similar to bract; bracts of second row orbicular, similar to innermost 
bracts but smaller ; bracteole of second row similar to bracts ; 
perianth broadly fusiform, 2 cells thick to a little above the middle, 
the rest 1 cell thick, terete below, irregularly 3-keeled above, 
mouth irregularly lobed, the lobes subdenticulate with teeth formed 
by sightly projecting obtuse cells: 3 spike usually occupying a 
short postical branch, sometimes terminal on a lateral branch ; 
bracts in 4 to 7 pairs, concave or almost complicate, broadly ovate, 
bifid about one-third with triangular, acute lobes and acute sinus ; 
bracteoles ovate, bifid about one-fourth with subulate, parallel lobes 
and obtuse sinus.

Hawaii (Menzies). West Maui (Baldwin). 
Lepidozia australis differs from L. reptans (G. & R., Hep. Eur., 
No. 479) in the following characters: the stems are more robust, 
the branches rarely branching and usually attenuate; the cells of the 
stems have much thicker cell-walls ; the leaves and underleaves are 
not as deeply lobed; the leaves are more obliquely inserted and 
spreading (while in Z. reptans the leaves are concave, the lobes 
strongly incurved), the lobes are much narrower, usually only 4 cells 
wide (in the European species the lobes are usually 6 to 12 cells 
wide); the leaf-cells are larger, with much thicker cell-walls and 
with larger trigones ; the mouth of the perianth has shorter teeth. 
Subgenus Microlepidozia Spruce, 1876. 
Plants usually small, depressed-czespitose, sometimes larger and 
pendulous: leaves transversely inserted, deeply divided or parted : 
perianth unistratose ; mouth ciliate-laciniate.
