The cellular cryptogams show the same floristic relationships as do 
the vascular cryptogams and phanerogams, as evidenced by the known 
distribution of Schisma sikkimense Steph., Pogonatum miscrostomum 
R. Br., Pilotrichopsis dentata Besch., Meteortwm helminthocladum 
Fleisch., Leptohymenium tenue Schwaegr., and Plagiothecium necke- 
roideum Bryol. eur. About one-fifth of the total number of species 
found on Mount Pulog show northern affinities, and very few of these 
‘northern types are found in the Philippines south of the Benguet- 
Lepanto region. 
- The Australasian element in the Pulog flora, although not represented 
by a great number of species, presents several of special interest, and 
it is at least a peculiar state of geographical distribution to find here, 
associated with Himalayan types, a considerable number that must be 
considered characteristic of the Australasian flora. Prominent among 
these are Paesia luzonica Christ, allied to a species from New Caledonia, 
Blechnum fraseri var. philippinense Copel., the species in New Zealand, 
Microlaena stipbides R. Br., the genus otherwise unknown from north 
of Australia, Carex graeffeana Boeckl., also in Fiji, Ayllinga intermedia 
R. Br., Formosa, Australia, and Fiji, Schoenus apogon R. &. S., and 
S. axillaris Poir., the latter now for the first time reported from north 
. of Australia, Uncinia rupestris Raoul, the first representative of the 
genus to be found north of the equator in the eastern hemisphere, and
