midribs of the leaflets, containing tetrasporangia in a double row. The 
colour is a dark brownish-red, becoming darker in drying. The substance is 
coriaceous and tough, and in drying scarcely adheres to paper.

Frond originating in a narrow, undivided, primary leaf, 10 cm. to 15 cm. 
long, and scarcely 5 mm. in breadth, of a membranaceous or subeoriaceous, 
thickish substance, tough and not adhering to paper, tapering at the base, 
but very blunt and subemarginate at the apex, traversed by an internal rib,

and having its surface on both sides densely asperated with minute, 
lanceolate ramenta, 2 mm. or less in length, with involute tips. This 
primary leaf throws off, from various parts of its midrib, leaves similar 
to itself, 5 cm. to 8 cm. long, and 4 mm. to 6 mm. wide, clothed in like 
manner with ramenta; and these also produce other phyllodia. In old 
specimens the primary leaf is converted into a stout, winged, woody stem ; 
and many of the ramenta are more or less compound. Stichidia compound, 
scattered along the disc of the phyll odium, generally near the margin, 
pedicellate, very much branched in a corymbose manner, the corymb with 
three or four primary branches each of which produces several distichous, 
secondary stichidia, strongly involute or circinate, containing a double row 
of tetrasporangia, and bearing other proliferous, minute stichidia from 
their inner faces. Colour, when dry, reddish-brown.
