Dixon: NEw MossEs FROM MALAY PENINSULA = 235 
Folia conferta, imbricata, perconcava a basi cordata late ovato- 
orbicularia, cucullata, abrupte in acumen circa 1% longitudinem 
folii aequans, loriforme, acutissimum fortiter denticulatum 
contracta, ecostata; marginibus toto ambitu superiore argute 
tenerrime denticulata. Cellulae superiores sinuato-rhomboideae, 
parietibus incrassatis porosis sed tenerrimis, ideo cellulae velut 
conflatae; basilares angustiores, infimae saepe aurantiacae, 
alares nonnullae aurantiacae, subinflatae, auriculas parvas bene 
notatas instruentes. Cetera ignota 
. Sempang, Fraser Hill, ES 1911; Ridley (282). 
With the leaf form and structure of M. rufescens, but more 
slender than any of its forms and without the glossy texture of 
that species; the leaf-point also is wider and more rigid than is 
usual there; the dense habit is also characteristic. . 
NECKERACEAE 
Endotrichella plano-marginata Dixon sp. nov. 
E minoribus generis; caules 3-4 cm. alti, densifolii, folits 
patulis, frondes 4-5 mm. latas formantibus; folia late cordato- 
ovata, 3-3.5 mm. longa, 2 mm. lata, apice raptim in cuspidem 
brevem, latam, fortiter dentatam contracta, plicata, marginibus 
omnino plania, superne magis magisque fortiter denticulatis; 
costae nullae; cellulae parvae, superiores 40-55 uw longae, lumine 
5-8 uw lato, parietibus incrassatis; basilares elongatae, angustae, 
alares numerosae, multo latiores, subquadratae, pellucidae, 
alas minusculas conspicuas instruentes. 
Fructus ignotus. 
HAB. Batu Caves, Selangor, 1896; Ridley (472). Base of 
a large tree in jungle, Sekong, Brit. North Borneo, 1913; Bin- 
stead (185). 
he generic position of this species in the absence of fruit 
must remain doubtful, but whether it be an Endotrichella or a 
Garovaglia it is a distinct new species. Very few of the species 
of these genera have the leaf margin plane, and. from those with 
this character the small size, small rounded leaves, small cells, 
conspicuous alar cells, and sharply toothed robust apiculus will 
separate it without difficulty. Garovaglia arisiata is perhaps 
the most like it, but has finer, quite entire apiculus; while G. 
densifolia Thw. & Mitt. has almost entire leaves and much 
larger cells.
