above; veins 3— 7-jugate, simple. Fertile fronds as long or shorter, narrower, 

 often on the longest stipes; pinnae contracted, with shorter and narrower, 

 more distant, spreading lobes; lowest pinnae not deflexed, except when casu- 

 ally barren.

Rhizome stout, woody, erect. Stipes of barren fronds 5—8 c.M. long, 

 erect, densely fibrillose-tomentose. Barren fronds 10 — IB c.M. each way, 

 deltoid, 3-pinnate. Pinnae close, only the lowest pair with pinnate pinnulae; 

 ultimate divisions oblong-romboidal, V2 — 1 C-M. long, the base equally cuneate, 

 the outer edge slightly toothed. Texture herbaceous; rachises tomentose. 

 Fertile fronds on slender, rather naked stipes 13—20 c.M. long, panicled, 

 with a few distant, slender, simple or compound, beaded branches.

 chum stenosemioides, Bk., Journ. of Linn. Soc, Bot., XXII, 230. 



Stipes of barren fronds to + 30 c.M. long, castaneous, covered with 

 a few lanceolate scales towards the base. Fronds oblong-lanceolate, 30 — 45 

 C.M. long, 16 — 20 c.M. broad, 2-pinnatifid. Pinnae sessile, multijugate, lanceo- 

 late, pinnatifid, the lower ones to 12 c.M. long, 272 — 3 '/a c.M. broad, the 

 margin beset with a few hyaline, deciduous scales. Segments oblong, obtuse, 

 4 — 6 m.M. broad. Texture submembranaceous ; surfaces naked; main veins 

 pinnate in the segments; veins 6— 8-jugate, the lower ones forked, the higher 

 simple. Fertile fronds similar, but the pinnae smaller, less dense, the stipes 

 ± 60 c.M. long.
