From P. leucosticton it differs chiefly by its ‘sub- 
phlebioid venation; the fronds are not subdimorphous 
but rather alike, broadly deltoid or broadly ovate- 
oblong, the fertile ones on longer stalks, but their 
lamina not linear-oblong as in P. leucosticton. Leaves 
variable in size and division, lobate, deeply pinnatifid 
or even pinnate below. Pinnae or segments of larger — 
fronds 8-10 pairs, 5 em. long, 1 em. broad, coarsely ser- : 
rated toward the apex. Texture very thick. Surfaces 4 
of young fronds clothed with ovate, lacerato-ciliate, 
brown scales, those of the under side numerous but not 
covering the whole surface; surfaces with age naked. - 
Stipe and rachis beneath, when young, chaffy by thin, ‘ 
pale yellow, lacerato-ciliate or dentate, lanceolate 
scales, the larger of which (especially those of the lower 
part of the stipe) have a dark brown or black midline. 
Rhizome about 5 mm. thick, densely clothed by small 
carinate, lanceolate scales, consisting of a lanceolate- 
acuminate, black, rigid median part bordered by broad, 
hyaline, pale yellow, fimbriate margins.

A comparison of authentic specimens from the type — 
collection, in the Botanical Museum of Copenhagen, — 
of P. pleopeltidis Fée (Glaziou 2459 and 2817) and of — 
P. typicum Fée (Glaziou 5294) has convinced me that 
the two supposed Species are forms of a single specles- — 
P. pleopeltidis is, as illustrated by Fée, a rather large — 
form rivalling P. plebejwm in size, with distant and — 
(towards the acute apex) more or less coarsely crenate . 
Segments. P. typicum is smaller, with more approxi-
