COLLECTION OF BORNEAN MOSSES. 313 
NECKEROPSIS GRACILENTA (Bry. jav.), Fleisch. Sekong (No. 100); 
pendulous from rotting stump by jungle-path, in a large sheet, Melalap 
near Tenom (No. 183). 
HoMALIODENDRON GLOSSOPHYLLUM (Mitt.), Fleisch. Jungle, Sekong 
(No. 110). This agrees quite well with Hooker’s Sikkim plant, No. 710, 
Hb. Ind. Or. Its distribution hitherto has been Eastern Himalayas, 
Yunnan, Formosa. 
HOMALIODENDRON (§Circulifolia) FrEmcHERL Dixon, sp. nov. (РІ. 27. 
fig. 14.) 
Caulis primarius tenuis, rigidus ; caules secundarii demissi, 8—4 ст. longi, 
parcissime breviter subpinnatim ramosi, frondem angustam percomplanatam 
lete-virentem pernitidam instruentes. Folia perfecte complanata, valde 
regularia, frondem ad 4-5 mm. latam sepius obtusam rarius flagelliformem 
formantia, oblongo-cultriformia, valde asymmetrica, pertruncata, uno margine 
infra late ineurva, e basi perangusta supra sensim dilatata, latere antico 
valde convexa, postico concava, in summo folio (ubi latitudo maxima) 1 mm 
lata, ibique valde truncata, medio tantum indistincte obtuse conico-apiculata, 
tenuiter conferte denticulata, margine convexo obscure crenulato-denticulato, 
margine concavo integro. Costa simplex, tenuis, 2—3 folii attingens, apice 
sepe dilatata, male delimitata. Areolatio perangusta, cellule prope basin 
lineares, supra sensim breviores, rhomboideæ, summitatis minute breviter 
elliptiez ; cellule lateris concavi ubique longiores eis lateris conve. 
Dioicum. Flores masculi parce in axillis foliorum, bracteis perigonialibus 
rigidis, apieibus obtuse linguatis, divergentibus. 
Cetera ignota. 
Hab. Shaded rocks in jungle stream, Tenom, 10 May, 1913 (No. 181). 
А striking plant, conspicuous by its thin, glossy, fern-like fronds with the 
leaves very regularly and closely set, and of a very distinct outline, recurved 
eultriform, the summit widely truncate, almost rectilinear, with only a small 
median prominence as in some species of JVeckeropsis (e. ©. N. gracilenta). 
The areolation is also remarkable, the cells on the concave side of the leaf 
being always considerably longer than those of the convex side at the same 
height ; on the former side, in fact, remaining linear almost to the summit. 
I sent this plant to Herr Fleischer, queried as Neckeropsis; he replied : 
“181 ist keine Veckeropsis! ich könnte sie vorläufig nur bei Z7omaliodendron 
n. sp. (Circulifolia Gruppe proxim.) unterbringen, jedenfalls ein eigenartiger 
Typus." 1 place it provisionally, therefore, under that Section. 
THAMNIUM ELLIPTICUM (Bry. jav.), Fleisch. Wet rocks in shade below 
waterfall, Sapong, near Tenom (No. 170). А good deal water-worn, forming 
dense mats. Hitherto recorded only from Sumatra and Java.
