urophyllum, with which Hooker united it. M. villomm, J. Sm., and M. Parishii, Beddome,
have pubescent and more herbaceous pinnæ than the form described above, and
M. Cumingii, Fée, is a glabrous form, with narrower and thinner pinnæ, the lateral
ones few or sometimes absent.

Hab. Mexico and West Indies to Brazil and Peru.—M. num'ophyllwm, Kze., appears
to be a form with a few large pinnæ. M. molle, Mett., gathered in New Granada by
iVI. Iriana, has the rachis and under surface softly hairy, and quite entire pinnæ 1 ft. 1.,
1 in. br., truncate on the upper and rounded on the lower side at the base. M. sorU-
jutmm, VVilld. (M. Kapplerianum, Fée), is a form with narrower pinnæ than usual, the
lower ones shghtly stalked. ’

Sori carried along the veins, imperfectly reticulated. A small genus o f closely
maea species almost restricted to the tropics, all with simple fro n d s o f firm hut
fleshy texture and copious uniform hexagonal areolæ. T ab. VI. fig. 6S.

continuous lines on each side of the midrib parallel with it, sunk in deep furrows

ine and Malayan Isles.—A. nanum, Fée, is as coriaceous in
texture, but not so plicate. In our specimens the fronds are oblong-spathulate, and only
1 in. 1., so that it is very doubtful whether the plant be not an undeveloped condition of
some of the other species.
5. A. plantagineum, Kaulf. ; f r . 6-9 in. 1., lJ -2 in. hr., broadest one-third of

6. A. Cumingii, Fée ; f r . 18 in. 1., 1-1J in. hr., ligulate, about equal in width
in the central half, narrowed very gradually to the base and an acute point,
