244 Dixon: New Mosses FROM MALAY PENINSULA 
2 mm. alta. Theca parva, elliptica, collo in setam defluente, 
erecta vel suberecia. 
H Borneo, Motley. Krangi, Singapore, 1895; Ridley

pore, 1896; Ridley (692, 693). 
This is intermediate between T. trachaelophyllum and T. 
sumatranum; it differs from the former in the characters detailed 
above, especially in the quite different cells; T. swmatranum has 
more acute, pointed leaves, and the papillae almost wanting; 
the inner perichaetial bracts also are much more finely subulate 
and flexuose. 
The papillae vary greatly, being at times wanting, at others 
very faint and scarcely to be detected except with great care, 
and at others quite well marked; they vary from 1-2 on each 
cell surface to 3-4. 
Taxithelium bilobatum Dixon sp. nov. (PLATE 4, FIG. 2) 
Subgen. Anastigma. Species praeclara. Habitus T. instrau, 
caulibus ramisque valde cgmplanatis, substrato arcte adpressis; 
(vetustate) fuscis. Folia octofaria, heteromorpha; ea serierum 
quattuor ventralium et dorsalium late oblonga, apice roiundato, 
obtuso, concava, pooatatae marginibus fere e basi arcte denti- 
culatis, apice denticulis ibus saepe recurvis 
quasi erosa. Cellulae breviter eiamitiiditiearis: lactis serie 
marginali breviores, pellucidiores; basilares infimae breviores, 
latiores, alares nullae. 
olia serierum quattuor lateralium majora, perconcava, seu 
lobis duobus conduplicaia, quorum uno minore breviore, altero 
majore longiore; a sinu plus minus profunde sejunctis; areolatio 
et marginum denticulato ut in foliis dorsalibus et ventralibus. 
Perichaetium breve, turgidiusculum, bracteis e basi latiore 
breviter late acuminatis, nec multo attenuatis, irregulariter 
dentatis, erecto-patentibus. Seta 2 cm. vel paullo ultra; theca 
(immatura) parva, brevis, basi in setam defluens; inclinata, 
operculo rostellato. 
HAB. Bujong Malacca, Perak; Ridley (739), in herb. Mitten. 
A very remarkable species, with the lateral leaves more dis- 
tinctly bi-lobed than in any other moss that I know. It is most 
nearly allied to T. glossoides (Bry. jav.), and the dorsal and 
ventral, undivided leaves are very similar to those of that species, 
but the lateral leaves are entirely different.
