﻿372 4S0. PTERIS. § 2. CAMPTERIA. 



Large, 120 — 180 c.M. high. Fronds deltoid-ovate, pinnate. Pinnae sub- 

 sessile, lanceolate, long-acuminate, deeply pinnatifid, the lowest to + 30 c.M. 

 long, with 1 — 2 pinnatifid branches on the lower side. Segments erecto-patent, 

 falcate-oblong, sterile ones broadly crenate, 3 — 4 c.M. long, 7 — 10 m.M. broad, 

 fertile ones crenate at their barren apices. Texture subcoriaceous : rachis and 

 surfaces naked; veins anastomosing in costal arches. Sori never reaching the 

 base or apex of the segments. — Scarcely more than a variety of Pt. biaurita, L. 



? Java, Philippines; Japan, China, South. India.

 pteria Wallichiana, Moore, Bedd., Ferns Br.L, I, tab. XXV; II, tab. CCXVII. 



Rhizome erect, clothed with roundish, entire or dentate, soft scales. Stipes 

 30 — 180 c.M. long, strong, naked, glossy, green or brown. Fronds 3-partite. 

 Central branch mostly 25 — 60 c.M long, 15 — 30 c.M. broad, with numerous 

 linear-lanceolate, sessile, opposite pinnulae on each side below the terminal 

 one. Pinnulae 7 — 15 c.M. long, to 3 c.M. broad, cut down nearly to the 

 costa into numerous flattened, conliguous, linear-oblong, rounded, finely toothed 

 or crenate lobes. Lateral branches similar to the central one and nearly as 

 long, forked near the base, the lower fork branch sometimes forked again. 

 Texture herbaceous ; rachises and both surfaces naked : veins not conspicuous, 

 commonly once forked. Sori constinuous along nearly the whole length of the 

 edge, or occupying the lower half of the lobes only.

* (39) IPi. heterophlebia, Jr«e, Bot. Zeit., 1848, 196; Campteria 

 heterophlebia, Moore, Ind., XLIII. 



Whole plant to l^^ M. high. Stipes yellowish. Fronds 5-partite; branch- 

 es to 60 c.M. long, to 25 c.M. broad. Pinnulae approximate, deeply pinnatifid, 

 10 — 15 c.M. long, to 4 c.M. broad, short-stalked, spreading, elongate-lanceolate, 

 subacuminale. Lobes falcate, oblong, with a broad base, the apex bluntish, 

 the edge crenato-serrulate, revolute. Texture coriaceous ; surfaces naked ; ra- 

 chises, costae and costulae subterete, the upper side flat, reddish-yellow- 

 brown, pubescent; main veins united at the base by arching veins, the other 

 veins free, forked, some of them forming here and there a single costular 

 areola in the lobes.
