 CXLVII. 



Rhizome short, stout. Stipes 15 — 45 c.M. long, firm, erect, nalced, basal 

 tubercles present. Fronds ovate-lanceolate, 30 — 45 c.M. long, 10—15 c.M. 

 broad. Pinnae linear, falcate, the largest + 7 '/a c.M. long, to 1 ^2 c.M. broad, 

 the lower ones narrowed at the base below, dilated at the base above, 1 — 2*/^ 

 c.M. apart, the apex narrowed gradually and finely toothed. Texture sub- 

 coriaceous; rachis naked; veins conspicuous. Fertile fronds similar, but the 

 pinnae more distant and narrowly linear.

Rhizome short, erect. Stipes approximate, 20 — 30 c.M. long, naked, cas- 

 taneous, the base thickened, without tubercles. Fronds pinnate, 40—60 c.M. 

 long. Barren fronds with ± 13 pinnae on each side. Pinnae nearly hori- 

 zontal, + 13 c.M. long, 1^2 — 2 c.M. broad, acuminate, serrulate, the lower 

 ones stalked, the higher ones adnate. Texture herbaceous; surfaces naked; 

 veins simple or forked. Fertile fronds with 12 — 16 pinnae, the pinnae linear, 

 + 10 c.M. long, 2 — 3 m.M. broad, stalked, or the higher ones adnate. — 

 Fronds with the aspect of Stenochlaena, and the absence of the basal projec- 

 tions of the stipes helps to conceal the real affinity. However, the oblique 

 annulus and the insertation of the sori establish the place beyond doubt 

 (Copel.).

 pinensis, Christ, Bull. Herb. Boiss., VI, 150. 



Rhizome erect. Stipes erect, naked, + 30 c.M. or more long, basal 

 tubercles present. Fronds ovate, 30 — ^150 c.M. long, 15 — 30 c.M. broad, pinnate, 

 the apex pinnatifid, narrowed. Pinnae contiguous, linear, 1^4 — 2 c.M. broad, 

 sessile or the lower short-stalked, the apex acuminate, the edge sharply ser- 

 rulate, but moz'e distinctly towards the point, the base rounded or narrowed, 

 often provided with a large gland beneath. Texture coriaceous; veins fine, 

 copious, compact, simple or forked; under surface glaucous or white-powdery. 

 Fertile fronds with the pinnae distant and narrowly linear.
