234 Dixon: NEw MOSSES FROM MALAY PENINSULA 
rather longer, those of C. aeruginosum and C. setifolium being 
sub-quadrate. The toothing of the marginal shoulder is different 
from that of C. setifoliwm, the upper teeth being few, and 
markedly rigid and spine-like, with a few much smaller ones 
lower down. The marginal cells of the base form a broad, pale 
border quite to the shoulder, which gradually narrows from there 
into the very narrow, thickened border of the lamina. 
Whatever its exact relationship be, it is a very distinct species. 
ORTHOTRICHACEAE 
‘Macromitrium magnirete Dixon sp. nov. 
§ Leiostoma. M. Zollingeri forsan affine. Sat robustum, 
dense intricatum, fuscum; caules densissime ramosi, ramis 
inaequalibus, .5—I cm. longis, foliis densissime confertis, siccitate 
inferioribus laxiuscule, apicalibus arcte spiraliter contortis, madi- 
dis patentibus. Folia circa 1 mm. longa, oblongo-lanceolata, 
e medio ad apicem acutum vel subobtusum angustata, costa 
excurrente longiuscule cuspidata; costa ad basin sat valida, 
profunde carinata, supra multo angustior; margine integro, 
basi uno latere reflexo. Cellulae magnae, 12-18 wu latae, mamil- 
losae, ovales, perincrassatae, infra sensim elongatae, basilares 
a lineares, rectae, grosse tuberculatae. Seta circa 
1.5 cm., laevis. Theca minuta, elliptica, laevis, microstoma. 
Calvaia laevis. Peristomium externum nullum; internum 
membrana altiuscula albida. 
HAB. Gunong Tahan, Pahang, 7000 ft., 1922; Mohammed 
Haniff and M. Nur (7907). 
Nearest to M. Zoilingeri and M. Blumii, but difcrties in the 
larger, highly mamillose cells, more acute leaf apex, and appar- 
ently in the peristome, which in both these species is double. 
The numerous capsules I have examined of the present plant 
show no trace of outer teeth, although some of them are in quite 
good condition; they are, however, all past maturity; and it is 
quite possible that the outer teeth may have been lost. 
MYURIACEAE 
Myurium subnitens Dixon sp. nov. 
Sat gracilis, statura M. sinici Mitt. vel M. quinquefarii 
Thér., sed ramis longioribus, flexuosis, densissime caespitesis, 
pallide fusco-viridibus. breviter cuspidatis haud vel vix nitentibus.
