﻿BS. DIPLAZIUM, § 1. EUDIPLAZlijM, 40^ 



Rhizome erect or decumbent, slightly clothed at the apex with lanceolate 

 scales. Stipes 10 — 30 c.M. long, firm, erect, naked, yellowish to brownish, 

 scaly at the base. Fronds + 20 — 60 c.M. long, ± 10 — 50 c.M. broad, ovate- 

 to triangular-lanceolate, with many or numerous spreading pinnae. Largest 

 pinnae 5 — 15 c.M. long, 1 — 2^2 c.M. broad, acuminate, or the upper ones 

 blunt or bluntish, the edges crenate and broadly, mostly shallowly lobed 

 (commonly to 2^2 m.M. deep), the base rounded, broadly cuneate or truncate, 

 whether or not auricled on the upper side; lower pinnae stalked, upper 

 sessile; apex of the frond deeply pinnatifid. Texture thin, herbaceous; veins 

 pinnate in the lobes. Sori long, linear.

(8) D. acrotis, Chri»t, Bull. Herb. Boiss., 2« S6rie, VI, 1000. 

 Rhizome oblique, short. Stipes tufted, numerous, 3 — 4 c.M. long, slender, 



pale-castaneous like the rachis, crinite with subulate, black-brown scales. 

 Fronds caespitose, 12—14 c.M. long, ± 3 c.M. broad, pinnate, the rachis 

 slender, nearly filiform, not winged, sparingly furfuraceous. Pinnae ±14 

 on each side below the pinnatifid, acuminate apex, ± horizontal, stalked, 

 regular, oblong, ± \\ c.M. long, + 8 m.M. broad, subfalcate, the base 

 cuneate on the lower, truncate and prominently and acutely auricled on the 

 upper side, the edge coarsely toothed with 5—6 teeth on each side, the apex 

 bluntish 'or acute; lower pinnae becoming shorter, higher sessile. Texture 

 herbaceous; veins 1 to each tooth, simple, the lowest anterior one pinnate 

 in the auricle. Sori oblong, oblique, regular, reaching the midrib and the 

 edge, often double.

Rhizome short-creeping. Stipes erect, 372 — 5 c.M. long, clothed above 

 with lanceolate, spreading, brown scales. Fronds oblong-lanceolate, simply 

 pinnate, naked, 10 — 15 c.M. long, 3V2 — S c.M. broad; rachis covered with 

 small scales. Pinnae multijugate, sessile, lanceolate, the higher ones entire, 

 the lower ± 5 m.M. broad, deeply crenate, with the lower base reduced; 

 veins obscure, erecto-patent. Sori in 1 row on each side of the costae, 

 linear-oblong, often diplazioid; indusium broad, membranaceous, naked, per- 

 sistent.
