nerves obsolete, surface covered with short appressed hairs ; 
fruit dots placed only at the upper part of the pinnules, few, 
two ranked, large, oval. 
59. PecorrERis norata (spec. nov.). Frond tripinnate ; 
secondary pinnz horizontal, short, linear-lanceolate, obtuse ; 
pinnules short, oval, or half round, united nearly to the 
middle ; terminal leaflet large, oval, obtuse ; nervules strongly 
marked, forking once, attached at an acute angle to the 
undulate medial nerve, rachis striate ; fruit dots very small, 
punctiform, irregularly placed along the nervules and between 
their branches. 
60. Pecopreris PusiLLA (spec. nov.). Frond bipinnate ; 
pinnz oblique, linear, nearly decurrent on a broad, flexuous, 
and winged smooth rachis; pinnules very small, united above 
the middle, oval, hairy, the lowest a little larger; nervules 
simple, obsolete. 
61. Pecoprerts concinna (spec. nov.) Frond bipin- 
nate; pinnz open, with an undulate rachis; pinnules about 
one inch long, oval, lanceolate, narrowed at the base and 
sessile, distant and perpendicular to the rachis, pinnately 
undulate, lobed; medial nerve undulate; secondary nerves 
pinnately forking three or four times in each lobe ; nervules 
simple. 
62. Pecopreris pECURRENs (spec. nov.) Frond bipin- 
nate ; pinnz opposite, superior ones terminal by the forking 
of the rachis; pinnules distant, oval, oblong, obtuse, entire, 
contracted above the base on the upper side, dilated on the 
lower, and decurrent on the broadly winged rachis ; medial 
nerve undulate, scarcely broader than the lateral ones which 
are simple, or once forked, arched; primary rachis flat- 
tened, broad, enlarged at the articulations of the pinnze. i 
63. Pecorrerts rwcowPLETA (spec. nov.). Frond ,bipin- 
natifid; pinnze very oblique, scarcely open, lanceolate ; pin- 
nules oval, or nearly round, decurrent, united at the ote 
very oblique ; the superior one very small, and the terminal 
wanting by the elongation of the secondary rachis pointing
