W. H. PEARSON: HEPATIC. 19 
HYMENOPHYTUM MALACCENSE St. in Hedwigia, xxxiv. (1895) 46; Sp: Hep. 
i. (1900) 307. 
Obs. Marginal cells small; they, along with the 2 to 3 adjoining cells, 
firm ; costa very broad, 5 cells thick and 15 cells broad, inner cells large, 
cortical cells small; 5 rows of double cells on each side of costa. Belongs 
to the Podomitrium section, as also does 77. Phyllanthus (Hook.), from which 
it differs in being smaller, more rigid in texture, with much larger cells. 
Hab. Ignambi. On gneiss rocks, in moist air, 3000 ft. 1531-1532. 
HYMENOPHYTUM FURCATUM Pearson, sp. nov. 
Dioica (?), mediocris vel elatiuseula pallide viridis cæspitosa. Caules 
basin versus radiculosi ; inferne exalati superne anguste alati furcati bifur- 
cative, segmentis circa 10 latitudine æqualibus regularibus integris apice 
.retusis, alis e. 20 cellulas latis, cellulis majusculis magnisve quadratis vel 
oblongo-quadratis leptodermibus, trigonis nullis; cellulis marginalibus 
similibus vel parvulis. Costa sectione transversä oblongo-eliiptica plano- 
convexa, antice convexa postice plana vel convexula, 8-12 cellulas crassa 
15-20 cellulas lata, eellulis peripherieis 50 et interiores simulantibus ; costa 
fasciculis axialibus 1-2 fuscis e cellulis angustissimis compositis percursa. 
Dimensions. Stems 1 to 14 inch long ; segments 1°25 mm., 1:5. mm., and 
2 mm. wide; costa *J mm. thick x:6 mm. broad, 2:25 mm. x:5 mm. ; cells 
“075 mm. x:05 mm. 
Obs. Belongs to the Umbraculum section ; differs from H. flabellatum 
(Hook.) in its much larger size, segments one-half as many and not flabelli- 
form ; cells twice the size, usually elongate, with thin walls and no trigones ; 
in H. flabellatum the walls are somewhat thick with distinct trigones. 
Hab. Mont Canala. Covering rocks, near creek, 2500 ft., damp forest.
