Scandent, the branches pendant, to 9 M. long, pinnate. Pinnae pinnate 

 again. Pinnulae (both sterile and fertile) + 20 c,M. long, + 2 c.M. broad, 

 the lateral ones 1 — 2 on each side, simple, on stalks 1 — :l*/s c.M. long, the 

 edges parallel, entire, the base truncate or auriculate, the terminal ones 

 simple or forked at the base. — Baker esteems this a species.

Primary petioles short or wanting, secondary ones to 3 c.M. long. Pinnae 

 15 — 30 c.M. long, 15 — 30 c.M. broad, the rachis + flexuose, narrowly mar- 

 ginate, with 2 — 7 pinnulae on 6ach side below the terminal one. Pinnulae 

 stalked, the terminal and higher ones free or joined, the base cordate, often 

 hastato-auriculate or palmatifid, the edge serrulate, the apex acuminate, acute 

 or blunt; central pinnulae hastatifld at the base, the lateral lobes similar 

 to the central one but much shorter; lowest pinnulae similar to the central 

 ones but the basal segments mostly free. Texture herbaceous; surfaces more 

 or less densely hairy, rarely subglabrous; rachises hairy or nearly naked, 

 costae rarely subnodose at the base. Fertile pinnulae similar to the barren 

 ones but shorter, 3 — 5 c.M. long, the lowest nearly always pinnate with + 

 1 — 3 leaflets on each side similar to the terminal one but smaller. Spikes 

 2—^10 m.M. long. Spores verruculose.

Primary petioles short, to 1 c.M. long, secondary ones 1 — 2'/, c.M. long. 

 Pinnae 10 — 20 c.M. long, nearly as broad or narrower, + deltoid in outline, 

 pinnate, the rachis ± flexuose, marginate (narrowly winged) especially towards 

 the apex. Pinnulae + 2—5 on each side below the terminal one, not ar- 

 ticulate, the higher and terminal ones simple, free or confluent, elongate, 

 linear-lanceolate, the base cuneate or subcordate, the apex bluntish, the edge 

 coarsely crenate or toothed and crenate, or lobed in the lower part; central 

 pinnulae hastate or subpalmatifid, the lowest ones pinnate or 2-pinnate, the 

 rachis marginate, the segments similai- to the higher or central pinnulae but
