KEYS TO THE FERNS OF BORNEO 
Subgenus VII. LEPTOMAiJES. 
a. Segments narrowly linear 
■a 1 - Segments capillary or setiform. 
b. Stems erect, stipes densely tufted 
b 1 . Rhizome short-creeping 
62. Rhizome wide-creeping 
39. T. parviflorum Poir 
T. fceniculaceum Bory. 
Sarawak, Dutch Borneo, North Borneo. 
Malaya to Madagascar and Australia. 
T. gemmatum J. Sm., reported from Mt. Poe (from 
which place I have T. parviflorum ) in Sarawak, and from 
Dutch Borneo, is supposed to be distinguished from 
T. parviflorum by having a wide-creeping, instead of a 
short-creeping rhizome. 
40. T. trichophyllum Moore. 
Kinabalu. 
New Caledonia. 
39. T. parviflorum. 
40. 7 '. trichophyllum. 
41. T. Pluma. 
42. T. metfolium. 
41. T. Pluma Hooker. 
Sarawak, North Borneo. 
Malaya to Samoa and New Caledonia. 
42. T. meifolium Bory. 
Dutch Borneo. 
Reunion to Polynesia. 
I have in hand a considerable number of Bornean 
specimens with segments reduced to bristles, and they 
are certainly all one species, which is T. Pluma ; whether 
or not they are T. meifolium cannot be determined here. 
T. trichophyllum is a thoroughly distinct plant, of which 
I have seen no Bornean specimen. 
FAM. VII. POLYPODIACEAH. 
Key to generic groups. 
a. Sporangia not collected into definite sori, 
scattered over the back of the frond 
an Sporangia scattered along the veins in elon¬ 
gate, naked lines 
«2. Sporangia gathered into definite sori which 
are dorsal rather than marginal. 
b. Sori more or less round, naked 
6 1 . Sori roundish, with indusia. 
A. “ Acrosticheae.” 
R. Vittarieae and 
ram- 
Gymnog 
mitidese.” 
C, “Polypodieae.”
