﻿b06 60a. PHEGOPTERIS. § 5. GONIOPTERIS. 



Rhizome nearly creeping. Stipes approximate, slender, rufo-stramineous, 

 flexuose, 10 — 13 c.M. long, sparingly puberulous, and clothed with scattered, 

 pale-fuscous, subulate scales. Fronds ovale, ±13 c.M. long, ± 7 c.M. broad, 

 with a large, ovate, acuminate, coarsely lobed terminal pinna + 6 c.M. long, 

 ± 2 c.M. broad. Lateral pinnae 2 — 3 on each side, petiolulate, similar to 

 the terminal one or reduced, ovate or obtusely rhomboidal, the highest ones 

 adnate. Texture herbaceous: rachis and surfaces minutely puberulous; colour 

 bright- green; veins anastomosing; areolae + 4 on each side of the costae. 

 Sori round, in 2 rows on the lobes, + 5 to a row.

Stipe and rachis brownish, naked. Fronds deltoid-oblong, ± 75 c.M. 

 long, + 50 c.M. broad near the base. Pinnae ± 20 on each side below 

 the terminal one. Terminal pinna ± 15 c.M. long, + IV2 c.M. broad at 

 the base, narrowed gradually towards the entire, caudate, acuminate apex, 

 the edge cut + '/4-way down to the costa into oblong, blunt, subentire, sub- 

 falcate lobes; higher and central pinnae similar to the terminal one, sessile, 

 broadest and truncate at the base ; lower pinnae longer, broadest at the centre, 

 narrowed gradually towards the base, subpetiolate, the lowest pinnae with the 

 lowest lobes subdecurrent. Texture raembranaceo-herbaceous ; surfaces naked 

 or the costae inconspicuously villose; main veins pinnate in the lobes; veins 

 ± 12 on each side in the longest lobes, the lowest pair anastomosing. Sori 

 medial, close, small, occupying nearly all the veins except the highest ones.

 Becc. Polin., 5 & 7 ; Dryopteris imponens, C. Chr., Ind. Fil. 



Fronds very large, to 240 c.M. long or longer, to 75 c.M. broad or 

 broader, the main rachis very strong, canaliculate, densely covered with small, 

 brown, rigid, conical, subacute prickles mixed with capillary, deciduous scales 

 and small, yellow hairs. Pinnae to 45 c.M. long, ± 2^/2 c.M. broad or 

 broader, the lower ones short-stalked, the others sessile, spreading, rather ap- 

 proximate, broadly linear, acute at both ends, deeply crenate (toothed?) to more 

 than '/j on the way to the costa. Texture chartaceous; surfaces opaque; veins 

 close, 13 — 15 on each side of the main veins. Sori in 1 row on each side, close.
