236 Drxon: NEw MossEs FROM MALAY PENINSULA 
Pinnatella lingulata Dixon sp. nov. (PLATE 3, FIG. 11) 
P. liguliferae (Lac.) Fleisch. affine, sed frondibus et foliis 
percomplanatis, atque. foliis siccis minute transverse rugosis, 
siccitate quoque leniter longitudinaliter biplicatis; sine ullo 
limbo intramarginali. 
Frondes oblongae, bipinnatae; folia stipitis suberecta, haud 
reflexa, caulina e basi latiore uno margine late inflexo concava, 
late oblongo-lingulata, apice rotundato et breviter acuto, integro 
vel minutissime crenulato, marginibus planis; costa infra valida, 
apice cito angustata ibidemque saepe bifurcata, longe infra . 
folii apicem desinens; cellulae superiores minute ovato-hexagonae, 
incrassatae, dorso laeves, marginales magis elongatae, omnes 
basin versus longiores, basilares lineares. Folia ramulina minora, 
paullo acutiora. 
Fructus in parte superiore caulis et in ramis superioribus 
situs; seta I mm. longa, laevis; theca subaequilonga, elliptica, 
brunnea, operculo curvato rostellato; peristomium majusculum, 
pallidum 
HAB. Growing horizontally on upright tree-trunks, Gunong 
Tampin, 1800 ft. ait., Negri Sembilan, 1917; Burkill (2864). 
A rather marked species in having the leaves and branches 
very complanate, the marginal cells slightly elongate, and 
smooth. P. Kuhliana differs in the reflexed leaves of the stipes, 
smoother, more pointed, more ovate, concave leaves, and ve 
different cells; P. ligulifera Fleisch. in the not or less complanate 
habit, and other points. 
The transverse rugulosity of the leaves is minute, and 
best seen under the microscope, but is quite evident with the 
lens in the dry state. 
ENTODONTACEAE 
Clastobryum prionotrichum (Hampe in sched.) Dixon sp. nov. 
(PLATE 3, Fic. 14) 
Caules secundarii brevissimi, dense caespitosi, gracillimi, 
fusci (? propter vetustatem), saepe ramos flagelliformes micro- 
phyllos tenuissimos emittentes. Folia imbricata, erecto-patentia, 
vix .5 mm. longa, e basi angustiore ovalia; in acumen flexuosam 
subelotion subaequilongum argute denticulatum sat cito angustata; 
ecostata, pellucida, concava; cellulae anguste lineares, perpel-
