438 PLANTS FROM KEW CALEDONIA. 



n 



now proves to have been correct, my spGCimona having a few typical sori, 

 described below:— . . . . soris e pinn[X3 latere versus rhachiJom solitatini 

 oriundis, ellipticis, 2-2-5 mm. long. 1-1'5 mm. lat., horiim labiis daobus 

 equalibns, dimidio superiore apertis, minute donticulati?, rcceptaculo incluso. 



HYMENoniYLLUM SUBOBTUSUM Hoseustock (ex doscript.), Ignambi; 

 creeping over trunks in moist forest; 4000 ft.; rare. 1598, Franc's 

 original specimens were collected in a neighbouring locality — '^in monte 



Ta^, 800 m.alt, 1421," 



Tkiciiom-ixes album Blume. Mt. Mou ; on tree-trunks in cloud-forest ; 

 3700 ft. 481* The New Caledonian plant occurs only at higli altitudes. 

 I put my gatherings into this species rather than in 7\ pallidum Blume, 

 because oE the cuneatc-lanceolute piimtc ; 1\ pallidum is described as having 

 cuncate-oblong pinna?. Hooker and Baker reduce both species to one, 



T, pallidum. 



Blunio, who habitually mentions a montane habitat, states that his 



T. p^allidum grows ^' in Javai sylvis primrcvls/' while T. album ''crescit in 



Java} montibiis cxcclsis.'' It is probable that 7\ album would grow at a 



higher altitude in Java than in New Caledonia. Tropical Asia, rdyncsia. 



T, BArEPJANUM Endl. Mt. Panic; terrestrial in high forest; gneiss; 

 4000 ft. 1820. Malaya, Australia, Polynesia. 



T. BiruNCTATUM Poir. Ermitiige Stream; 300 ft. Mt. Canahi ; near 

 stream in forest ; 1000 ft. Mt. Arago ; creejdng "on earth among rocks by 

 forest stream ; 1000 ft. 181, 11G3, 1429. Japan, Formosa, tropical Asia 

 and Australia, Polvnesia, S. and AV* Africa. 



T. CUNEATUM Christ. Mt. Mou ; on tree-trunks in cloud-forest ; 3800 ft. 

 614 a. My specimens agree with Clirist^s description and figure, except that 

 the frond is generally not truly dichotomous. 



Christ's specimens come from "the to[) of Mt. Mou on rotten bark, very 

 rare.'' Posenstock's FiL J^ow CuL 51 is this species, collected by Franc on 

 Mt. Mou at 1200 m. Thus, as in tlio case of 1\ Francii (which this species 

 resembles in some respects), Mt. Mou is the only locality known at present. 



1\ DENTATUM Van den Bosch. Mt, Arago ; in damp stream-bed in forest ; 

 schists; 1000 ft. 1445- Polynesia. 



T. DIGITATUM Swartz. Ignambi ; on tree-trunks in cloud-forest; 3800 ft. 

 1G50. Not hitherto from New Caledonia, The fronds are sparsely setose 

 along the margins ; occasional setro are also present along the veins and 

 along the margin of the involucre — a connecting-link with the var. palmali-
