Hab. New Zealand.—This is the only species in which the frond has four layers of
cellules, and the habit is quite peculiar.

veins close, regularly dichotomous a t a small angle, with numerous interrupted
spurious venules between them a t the margin and towards the centre ; sori 1 to 3,
scattered, firm in texture, the tube more or less exserted, with a very much
dilated spreading slightly two-lipped mouth.—Baker in L in n . Froc, inedit, cum

Hab. Samoa, Rev. T. Powell; New Caledonia, Vieillard, 2166.—A very curious
novelty, quite peculiar in habit. “ The different branches of the caudex,” writes the
discoverer, “ run upwards, but so closely together, that the margins of the fronds overlap
each other. The fronds all lie flat upon the tree, so that the whole fern has much the
appearance of a delicate foliaceous lichen or frondose Jangerniannia.”
8. T. memhranaceum, L. ; f r . subsessile, membranaceous in tex tu re , suborbicular

fringed with a double series of peltate scales ; spurious venules copious ; invol.

Hab Tropical America, both the islands and continent.—Here, although the frond
is so thin, there are two or three layers of cellules, and the curious peltate scales of the
frond are unique. The habit is that of Radina pavonia amongst Algm or a broaddobed
Flustra.
