258 Dixon: NEw MossEs FROM MALAY PENINSULA 
Acroporium surculare Dixon sp. nov. (PLATE 2, FIG. 11) 
Caulis longe prostratus, sat robustus, irregulariter, subpin- 
natim ramosus, ramis erectis, vel patentibus, saepe subfasci- 
culatis, complanatis, subnitidis, sordide viridibus, 2-3 mm. latis, 
foliorum axillis surculos microphyllos capillares numerosos I-3 
cm. longos emittentibus. Folia 2 mm. longa, perconcava, e basi 
contracta late oblongo-ovata, marginibus incurvatis, apice 
subcucullata, raptim in acumen breviusculum latiusculum acutum 
denticulatum contracta. Cellulae angustissime lineares, Jaeves, 
parietibus sat tenuibus, indistinctis, inferiores paullo laxiores, 
infimae aurantiacae, alares plures hiyedene ny bees Srey 
Cetera nulla. 
HAB. On twigs, Bidor Road, Tapah, Perak, 1908; Ridley 
(153). Penang Hill, Pulau Penang, 1896; Ridley (551). 
Somewhat intermediate between A. complanatum (described 
above) and A. pycnophyllum (C. M.). Larger than the latter 
species, with complanate branches, and with the acumen of the 
leaf much shorter and not piliferous, but much narrower and 
shorter than in the former, the cells also in the present species 
are, so far as I have examined them, quite smooth. The flagel- 
liform ramuli are quite different from anything I have seen in 
the genus.
