In Seemann's Journ. Bot., 1869, p. 240, a second species 
is described, namely H. Seemanni, a native of Nicaragua, 
which is adopted in the "Synopsis Filicum " Addenda, 
p. 460. I have not seen specimens of this, 
102.—Tricutocarpa, J. Sm. (1866). 
Deparia, sect. Trichiocarpa, Hook. ; Cionidium, Moore. 
Vernation fasciculate, acaulose. Fronds bi-tripinnatifid, 
deltoid, 12 to 18 inches high, pinne distant, pinnate below, 
pinnatifid decurrent above ; pinnules lanceolate, pinnatifid, 
or sinuose lobed. Veins uniform, reticulated; areoles 
transverse oblong, marginal venules free, exserted beyond 
the margin, bearing globose pedicellate sori. Sporangia 
included within a calyciform indusium, opening exteriorly. 
Type. Trichiocarpa Moorei, J. Sm.

Oss.—This genus is founded on a remarkable Fern, a 
native of New Caledonia ; in habit it greatly resembles the 
multifid fronded specimens of Aspidium trifoliatum and 
allied species, but its marginal pedicellate sori marks it as 
specially distinct even as not belonging to Aspidee ; relying 
upon the character of the sori alone, there can be no doubt 
that Sir W. Hooker is right in describing it as a species of 
Deparia, but from which it differs, and from all Dicksoniæ, 
-in having anastomosing veins. 
_ In native and cultivated specimens that have come 
under my notice, I observed some of the sori to be intra- 
marginal, and even some of them seated on the upper side
