♦ (17a) A. squaiiiulatnin, JBI., Rac, Plor. Btz., I, 210; Tham- 

 nopteris stipitata, Pr., Epim., 68; — var. sessile. 



Rhizome short, creeping or erect. Stipes + tufted, 5 — 20 c.M. long, strong, 

 erect, scaly like the co'sta, the scales persistent or more or less deciduous. 

 Fronds 30 — 100 c.M. long, 3 — 10 c.M. broad, lanceolate, the apex blunlisb, 

 acute or acuminate, the ijdge entire or nearly so, the base narrowed gradually 

 into the stipe. Texture coriaceous; surfaces scaly at least when young, the 

 scales scattered, adpressed, minute; veins not very distinct, simple or 1 — 2 X 

 forked, + 2'/j m.M. apart. Sori reaching from near the midrib to 3 — 15 

 m.M. of the margin; indusium broad, membranaceous, naked. 



War. sessile: Stipes short or wanting. Fronds 20 — 25 c.M. long, 

 3 '/a — 5*/j c.M. broad; veins rather close; indusium + coriaceous. — United 

 with the type by intermediate forms (e. g. forma cahescens, Christ, in Ann.

 10 — 20 c.M. long, + densely brown-scaly. Fronds ovate-eloiigate, to 45 c.M. 

 long, to 6 c.M. broad, the apex obtuse and abruptly acuminate, the base nenrly 

 rounded or short-decurrent upon the stipe, the edge enl ire or obscurely repand. 

 Texture chartaceous; upper surface olive-green and slightly scaly, lower livid- 

 green and copiously scaly ; costa prominent, scaly ; veins erecto-patent, simple 

 or forked, + l*/j m.M. apart, parallel. Sori occupying the lower '/^ of the 

 veins; indusium entire.

acuminate, covered with short hairs near the base. Stipes + 1 c.M. apart, 



6—10 m.M. long, black, scaly. Fronds simple, 28—35 c.M. long, + 5 c.M. 



0^ broad, narrowed gradually towards both ends, but more or less suddenly at 



3 the apex into an acuminate point and towards the base into a narrow wing to the 



a> costa, the margin crenate, the lower, narrowed part entire. Texture chartaceous.
