2. Litohrochia aurita. (Blume.) Caudex long creeping, subterraneous, stipes and rachis castaneous, glossy fronds, ample sub- 
membranaceous, distant ovate, long stipitate, glaucous beneath, tripinnate, pinnae all sessile, subadnate mostly opposite horizontal, pinnules 
opposite sessile, lanceolate obtuse, more or less deeply lobed and pinnatifid. Segments ovate or oblong, (sterile ones subsinuate) or triangular, 
lowest one often remote and forming auricles on the rachis, superior ones confluent, veins all anastomosing, areoles next the costa and 
costules the largest and most elongated, involucres continuous or interrupted membranaceous entire at the edge. Hook. Sp. Fil. ii, 231

This species only differs from L. vespertilionis Labill, (L. incisn, Thunb.) by the anastomosing of the veins being always 
constant. Sir W. Hooker keeps them distinct, but Dr. Hooker unites the two in his " Flora3 Novae Zelandiae."

[a 3]. Receptacles short, transverse, or arcuate on the. venules, sub-parallel with the midrib or margin. 
SORI INDUSIATE— WoODWAEDIEiE. 
DooDiA. (P. Broivn.) 
(Woodwardia, Metten.) 
Sori oblong or sub-lunulate, in one or more series, arranged transversely with the veins forming areoles which are superficial, 
not sunk. Involucres membranaceous, of the same form as the sori, opening towards the costa and lying parallel with it. Veins uniform, 
the lower ones arcuately anastomosing, forming elongated costal areoles (one or more series), the marginal venules free. 
Fronds pinnate or pinnatifid. Segments or pinnse sharply serrated, rhizome sub-globose. 
1. Doodia dives. (Kunze). Rhizome obliquely ascending, paleaceous, radicoses clothed with black fibre, stipes angled brown, very 
paleaceous near the base, fronds coriaceous, glabrous ovato-oblong, long caudate at the apex pinnate, at the base with some of the lower 
pinnaj auricled, pinnatifid above, pinna3 and segments patently divergent, oblong margins pungently serrated, pinnae or segments 
of the fertile fronds often distant, sori in 1 or 2 series on each side of the costa of the pinnae and segments, and also on the wings of the 
raeliis, lunate often more or less confluent. Hook. Sp. Fil., iii, 73.

MENISCIEiE. 
Meniscium. See page 19. 
1. Meniscivm Thtvaitesii. (Hook). Caudex creeping more or less scaly, and furnished with wiiy roots, stipes angled, very long 6 
inches to 1 foot, and with the rachis puberulous, fronds deltoid, 6-8 inches long, 4 inches broad at the base, pinnated, pinnatifid at the 
apex, pinnae alternate or opposite, lanceolate rounded at the base, obtuse or acute or caudate at the apex, crenato-lobate, lower ones much 
the largest, costa and veins puberulous especially beneath ; sori linear, oblong becoming confluent. 
Mr. Thwaites informs me that Sir W. Hooker thinks that this may be only a variety of Goniopteris prolifera,
