The caudex of this is creeping, but as well as the roots, often 
densely covered with a mass of olivaceous tomentum, so as 
scarcely to be visible. Where the tufts of fronds arise the 
caudex is seen to be paleaceous with subulate scales. F ronds 
membranaceous, flaccid, three inches to a span, or almost a 
foot lono-, one-third of an inch wide m the broadest pait, 
narrow, linear-lanceolate, accuminated, ecostate, much taper- 
ino- below, but not stipitate; a darkish line indeed runs through 
the very narrow base, but nothing that can be called a. mid- 
rib. The sori vary in form. In one specimen two uninter- 
rupted longitudinal lines run for a length of five inches between 
the centre and the margins, and a third but shorter continu- 
ous line appears between one of these and the margin ; in 
other specimens the sori form two to four somewhat parallel 
lines, here and there branched and variously interrupted ; all 
are sunk in a channel or groove in the substance of the frond, 
and all arise from the veins which run longitudinally, while 
oblique veinlets unite them so as to form very elongated 
areoles. 
I can no where find any Fern described corresponding 
•with this. It seems to approach the Antropli • angustatum of 
Brackenridge from Tahiti; but that has a stipes four inches 
long. It very much resembles in general aspect the Antroph. 
lineatum, Kaulf. (Polytaenium lineatum, Desv. and Hook. 
Gen. Fil. Tab. CVII.), but that has copious parallel sori and a 
distinct costa. Our Antrophyum Galeottii (see Tab. LXX. 
of this volume), has the areoles and sori oblique.
