 subbipinnate, pinnae ovato-lanceolate acuminate alternate

 fluent, inferior pinnae pinnate at the base 3 inches long 1 

 inch wide, pinnules oblong acute crenate 1 inch long, rachis 

 and costules glabrous naked ; fertile frond tripinnate, pri-

 Wright, n. 786. — I fear the composition of the fertile fronds and the relative 

 length and breadth of the ultimate pinnas are too variable to afford really stable 

 characters for this and the three or four preceding species. This is, however, the 

 one on which the genus Polybotrya was established, 



104. A. (Polybotrya) Lechlerianum, Hook. ; caudex thick 

 elongated scandent paleaceous with ovate very acuminated 

 brown scales, stipites pale-brown glossy a span long 2-3 lines 

 wide scaly below ; sterile frond 3 feet and more long sub- 

 membranaceous firm villous broad-ovate acuminate tripin- 

 nate, primary pinnae subsessile a span to a foot long distant 

 ovate acuminate, secondary ones approximate numerous, 

 pinnules ^ of an inch long very numerous ovato-oblong 

 deeply pinnatifid, the segments oblong very acute slightly 

 falcate each with a single vein clavate at its apex and not 

 reaching to the apex of the segment; fertile frond ramified 

 as the sterile one, the pinnules short 2-4 lines long linear 

 very obtuse lobato-pinnatifid soriferous beneath chiefly near 

 the margin. — Polybotrya, Metten. in Lechl. PI. Perim. n. 2156,
