of the Tribe Trigonanthee. 13 
cal margin slightly dilated near the base; line of insertion curved 
slightly inwards: underleaves imbricated, more than twice as broad 
as stem, orbicular, apex subretuse or repand, sometimes irregularly 
dentate, base cordate, lateral margins entire and somewhat reflexed : 
cells at apex of leaf thick-walled, with irregular cavities and large, 
sometimes confluent trigones, in the middle with elongate, substellate 
cavities and large triangular to orbicular, often confluent trigones, 
at the base with large, stellate cavities and large trigones ; cells of 
underleaves similar to those of leaves: 2 inflorescence borne on a 
very short branch; 9 bracts in about 5 pairs; innermost bracts about 
the length of the leaves, broadly ovate, upper half irregularly denticu- 
late, teeth 1 to 3 cells long, apex deeply 2 to 4 laciniate (about one- 
fourth), innermost bracteole similar to bracts; perianth ovate, terete 
below, many keeled above, mouth somewhat contracted, irregularly 
lobed, lobes laciniate, laciniae denticulate, 8 to 10 cells long, 4 to 6 
cells broad, ending in a row of 4 or 5 cells; cells of perianth elon- 
gated, with much thickened walls: capsule oval, dark brown; spores 
light brown, minutely verruculose; elaters tapering toward the ends, 
blunt. . 
Stems 0.3™™ in diameter; leaves, antical axis 1.3™™ to 1.55™™, pos- 
tical axis 1.0™™ to 1.2™™, breadth (greatest) near base 0.9™™ to 1.1™", 
at apex 0.35™™ to 0.4™™, leaf-cells at base of median tooth 26ux19p, 
in middle of leaf 26ux21p, just above base 42ux24y, extreme base 
45, antical edge 154; underleaves 0.77™x0.85"™ ; cells of under- 
leaves 38ux22u; perianth 2.2™™x1.5™™"; innermost bracts 1.5™"x0.9™™; 
bracts of second row 1.2™™x0.75™™; spores 20u; elaters 400ux15p. 
Hawaiian Islands (Gaudichaud, Hillebrand, Tolmie, Douglas). 
Hawaii (Beechey, Macrae). West Maui (Baldwin). Oahu (Mann 
& Brigham); Nuuanu, Konahuanui (Cooke). Kauai: Kilohana 
(Cooke); base of Pohokupili (Wawra). Very common from 1000 
to 5000 ft., growing on the ground. 
This species is closely related to B. falcata, of Nepal. <A part of 
the type-material, from the herbarium at Kew, has been used for 
comparison. B. falcata differs from Lb. cordistipula in its larger 
leaves (length, antical 2.7™™, breadth at base 1.6™™, at apex 0.35™™), 
which are much more falcate and bear one or two teeth at the posti- 
cal base; the leaf-cells also are much larger with stellate cavities and 
larger trigones, measuring at apex 27m, in the middle 45yux30p, at 
the base 45ux38p, and along antical edge 27p.
