Dixon: NEw MossEs FROM MALAY PENINSULA 243 
Taxithelium isocladioides Dixon sp. nov. (PLATE 4, FIG. 1) 
T. isoclado (Bry. Jav.) affine atque simile, differt foliis angusti- 
oribus, perfecte lanceolatis nec ovato-lanceolatis, longius argutius 
acuminatis, sat fortiter denticulatis, cellulis majoribus, tenerrime, 
saepius indistincte seriatim papillosis. Cetera ut in T. isoclade.

With the habit and fruiting characters of T. isocladum (so 
far as seen) this differs quite markedly in the much narrower 
and more narrowly acuminate leaves, the sharply denticulate 
margin, and the larger, pellucid cells, only very minutely and 
usually quite indistinctly papillose. In fact it might easily be 
mistaken for an Isopterygium. 
Taxithelium trachaelophyllum (C. M. in sched.) Dixon sp. nov. 
LATE 3, FIG. 17) 
T. Gottscheano Hampe forsan proximum; differt foliis rameis 
percomplanatis, perfecte rotundato-obtusis, rarissime latissime sub- 
acutis; cellulis indistincte, minutissime, humillime papillosis, 
alaribus majoribus, elongatis, incrassatis, saepe aurantiacis. 
Fructum haud vidi.

This was determined as Hypnum trachaelophyllum C. M., 
but has not been published. It is nearest to T. Gottscheanum 
Hampe and 7. capillipes, both of which differ in the more pointed 
leaves, and the smaller and less distinct alar cells, while T. 
Goitscheanum also has the cells quite distinctly seriate-papillate; 
in the present plant the papillae while present and seriate, 3-4 
on a cell face, are extremely low and often quite indistinct and 
with difficulty seen. 
Taxithelium subtrachaelophyllum Dixon sp. nov. (PLATE 3, 
Fic. 18) 
T. trachaelophyllo (v. supra) affine; foliis autem angustioribus, 
apice minus rotundatis, cellulis duplo majoribus, parietibus 
firmioribus (eis T. trachaelophylli pertenuibus), alaribus minoribus, 
paucioribus; papillae perindistinctae, tenerrimae, 2-4 seriatae. 
Bracteae perichaetii in acumen subrectum rigide late lori- 
forme nec subulatum, subdenticulatum angustatae. Seta circa
