Hab. Fiii Islands, Milne.—TMk species rivals in minuteness IIymenophyllum parvifo-
Hum and the preceding. From this latter it is readily distinguishable by the absence ot
lateral veins, and the two are the only pinnate-veined species that are without spurious
venules.

Hab. Tropical America, Asia, Polynesia, and Africa.—Sir W. Hooker was disposed to
place here eight species of Van den Bosch, authentically represented in his collection ;
viz. muscoides, sublimbatum, cerugineum, eromm, Hookeri, Lenormandi, bimarginatum, and
Kapplerianum. The first of these is considered by that author as a, Hemiphlebium (mouth
distinctly two-lipped), and the two next he separates from the other five by the chiwacter
ot “ spurious venules free, joined together towards the margin.” T. Schaffiien, bohlt.,
T. Pabstianum, C. Mull., and T. erispulum, V. D. B., are closely allied plants not repre-
sented by name in the Hookerian collection.
