﻿610 71. POLYPODIUM. § 1. EUPOLYPODIUM. d. PINNATAE. 



Pinnae narrow, subacute, undulate, subfalcate, decurrent, the higher ones con- 

 fluent, the lower distant, reduced. Texture subcoriaceous ; rachis + hairy; 

 surfaces naked or nearly so; veins simple. Sori + elliptical, terminal on 

 the veins, medial between the costae and the margin, (oblique ? ), superficial.

Rhizome creeping, clothed with grey-fuligineous, lanceolate scales. Stipes 

 approximate, ± 5 c.M. long, clothed like the rachis with straight, castaneous 

 hairs. Fronds + 20 c.M. long, + 4V2 c.M. broad, pinnate, abruptly nar- 

 rowed at both ends. Pinnae suberecto-patent, straight or curved, + 2'/j c.M, 

 long, + 3^/2 m.M. broad, obtuse, decurrent, toothed, only the superior ones 

 confluent, the lower rather remote, abruptly reduced to mere auricles, the 

 teeth reaching '/j — ^/3-way down to the costa, distant, spreading. Texture 

 coriaceo-papyraceous ; costae and apices of the teeth setiferous; veins simple, 

 hidden. Sori superficial, occupying the bases of the veins, often opposite, and 

 the pairs not rarely confluent.

 petiolate; upper base parallel to the rachis, auricled, lower cuneate-truncate. 

 Texture subcoriaceous ; surfaces glabrous; veins 2 — 3-furcate. Sori medial 

 between the edge and midribs, terminal on the lowest anterior veinlets.
