ix, c, 3 Robinson: Distribution of Philippine Mosses 207 
ince come to be considered, their distribution proves to be quite in 
different proportion from that of the species more widely dis- 
tributed in the Philippines, as just detailed. The habitat of 
the former being at once more northern and on an average more 
elevated than that of the latter, it would be expected that they 
would show more northern alliances. It must be remembered, 
however, with respect to elevation, that while the Mountain 
Province as a geographic unit is on an average of much greater 
height than any other large area in the Philippines, from the 
standpoint of moss collections the difference is definitely less, 
as so many of these have been obtained here only on the tops of 
the mountains farther south. 
The actual figures obtained from these 60 species are that only 
12 are exclusively Malayan, that 22 are not Malayan, while the 
remaining 26 are found both in Malaya and elsewhere; with 
this additional qualification, that in many cases among the 26 
the species are more typical of regions west or north of Malaya 
but extend into the latter, whereas in the cases previously con- 
sidered nearly all were more typically Malayan but extended 
to other countries. 
The exclusively Malayan species are Trematodon paucifolius 
C. M., Dicranella coarctnta (C. M.) Bryol. Jav., Leiomela java- 
nica (Ren. & Card.) Broth., Pogonatum junghuhnianum (Doz. & 
Molk.) Bryol. Jav., and Fabronia curvirostris Doz. & Molk., these 
five reported outside of the Philippines only from Java; Braun- 
felsia dicranoides (Doz. & Molk.) Broth., only from Java and 
New Guinea; Pohlia leptocarpa (Bryol. Jav.) Fleisch. only from 
Java and Borneo; Barbella rutilans (Bryol. Jav.) Broth, and 
Oxyrrhynchium muelleri (Bryol. Jav.) Broth, from Java and 
Sumatra ; while Leucobryum scalare C. M., Macromitrium angus- 
tifolium Doz. & Molk., -and Taxithelium lindbergii (Bryol. Jav.) 
Ren. & Card, are of wider distribution within the Archipelago 
but do not exceed its limits, except that the first of the three 
is also reported from Singapore. 
Of the 26 species found both in Malaya and elsewhere, two, 
Bryum argenteum L. and Ceratodon stenocarpus Bryol. Eur., 
have a very wide distribution, and Anoectangium euchloron 
(Schw.) Mitt, has been reported from tropical America, tropical 
west Africa, and Java. Five others extend to the east or south 
of New Guinea, and three of these five also to the west or north 
of Sumatra; yet only one of them, Pilopogon exasperatus 
(Brid.) Broth., seems to be widely distributed in the group, 
extending also to Ceylon and Hawaii. Glyptothecium sciuroides
