﻿412 S5. DIPLAZIUM. § 1. EUDIPLAZIUM. 



entire; higher pinnae sessile, obliquely serrate at the margin, otherwise 

 similar to the medial ones; highest pinnae gradually passing into the lohes 

 of the terminal pinna. Texture charlaceo-herbaceous ; colour blackish 

 when dry ; surfaces naked ; costulae pinnate, slightly hirsute beneath ; veins 

 simple, to 8-jugate in the lower, to 3-jugate in the central pinnae. So- 

 ri copious, straight, parallel, reaching ± from the costulae to the edge; 

 iudusium firm, shortly fimbriate, pilose when young. — Near D. sorzogonense, 

 Pr. 



Sumatra.

Stipes tufted, 10 — 15 c.M. long, densely fibrillose below. Fronds 30 — 65 

 c.M. long, 20 — 35 c.M. broad, with numerous pinnae on each side, the lower 

 ones sessile, 10 — 18 c.M. long, + 2*/^ c.M. broad, + truncate at the base, 

 cut down regularly throughout ^/3 of the way down to the costa into spreading, 

 blunt, subentire lobes + 4 — 5 m.M. broad. Texture herbaceous, rachis slightly 

 fibrillose; main veins pinnate in the lobes; veins simple. Sori in regular rows, 

 reaching from the main veins to the edge. 



Var. major: Stipes + 75 c.M. long. Fronds 120 — 180 c.M. long. 

 Pinnae + 30 c.M. long, 5 — 7 ^j^ c.M. broad, the 3 lower pairs much deflexed, 

 cut down nearly to the costa into narrow, slightly crenated segments. Surfaces 

 naked; veins generally forked. — Perhaps a distinct species.

Stipes 20 - 40 c.M. long, black in the lower, dirty-brown in the upper 

 part, sparingly clothed like the rachis with narrow, spreading, flexuose 

 scales becoming smaller towards the apex of the frond Fronds 50 — 60 c.M. 

 long, + 30 c.M. broad, acuminate, hardly 2-pinnate, the apex pinnatifid. 

 Central pinnae largest, horizontal, acuminate, deeply pinnatifid, the base 

 truncate or subtruncate, with a short, black stalk ; lowest pinnae slightly 

 remote and reduced, sometimes deflexed. Lobes oblong, subacute, the largest 

 + 3 c.M. long, ± 1 c.M. broad, sharply serrate towards the apex, connected 

 at the base by a narrow wing, but some of them sometimes free, the lowest 

 lobes of the lowest pinnae reduced. Texture papyraceous ; upper surface black-
