often numerous, not rarely subpinnale, conspicuously narrowed or contracted 

 1 — 10 m.M. broad. Spikes 2 — 10 m.M. long. Spores verruculose. — 



Forma typica: Spores without crests. Laciniae entire, not dichotomoui 

 at the apex. 



War. monstruosnin : Spores without crests. Laciniae dichotomous 

 at the apex. 



War. denticulatum: Spores without crests. Laciniae denticulate, 

 not dichotomous at the apex. 



War. crislatuni: Like var. denticulatum, but the spores purveyed 

 with 6 joining crests. Laciniae ± 72 ""1 ^■^- broad. Sumatra (Burck). See 



Trop. Asia, Queensland. 



(4) Wj. digitatum, J*r., Prantl, Morph. d. Gefasscr., II, Schiz., 66; 

 L. dichoiomum, Sw., Rac, Flor. Btz., I, 8, p. p. 



Primary petioles nearly wanting; secondary ones 1^2 — 2 c.M. long, semi- 

 terete, mai-ginate. Pinnae 2-partite or subpinnate. Pinnulae short-stalked, 

 not articulate, digitate with 5 — 6 laciniae 7 — 10 c.M. long, + 1 c.M. broad, 

 the apex acute, the margin serrulate, not bordered by a hypodermical strand. 

 Texture subcoriaceous ; surfaces naked, upper surface glossy, the under one 

 opaque ; rachis reddish-stramineous, the hairs of the gemmiform apex blackish. 

 Fertile pinnae 2-partite, each segment with + 3 laciniae to 35 c.M. long, + 5 

 m.M. broad. Spikes to 6 m.M. long. Spores rather large, coarsely tuberculate.

 Gefasscr., II, Schiz., 67; L. circinafum, Sw., var. Irifurcntimi, Christ, in Warb., 

 Mons., I, 95. See the Appendix. 



Primary petioles very short or obsolete, secondary ones 272—4 c.M. long. 

 Pinnae forked, 3-furcate or 2 .X forked and each division 2-partite nearly to 

 the base. Ultimate bai-ren segments 10—15 c.M. long, + 2— 27^ c.M. broad, 

 not articulate, the point acute or blunlish, the edge crenulate. Texture sub- 

 coriaceous; rachis and surfaces naked. Fertile pinnae -varying. from, dichotomous 

 to B pinnate, the divisions contracted and often cut down nearly or quite to 

 the costa with the short spikes in groups of 3—6 upon the lobes. Spores 

 coarsely verrucose. — The Banca plant (leg. Berkhout) has the spikes rather 

 long, in groups of 1 — 3, and the spores verruculose and crested. Probably 

 an intermediate form between this species and L. circinatum, Sw.
