 BL, Nova Acta, XI, 122, tab. XIII, fig. 1 A, a^b. 



Forma nana: Stipes to 1 — i^j^ cm. long; fronds to 3'/^— 4'/j cm, 

 broad ; lobes subentire to crenulate, 



{8a) H. rroinwelliana. JR*f., in Fed., Rep., X, 324. 



Rhizome wide-creeping, bluish, densely clothed with ferrugineous, 

 lanceolate or ovate, membranaceous, flaccid, fimbriate, crispato-apiculate, 

 subadpressed scales. Stipes remote, flexuose, to 15 cm. long, black-brown, 

 somewhat glossy, deciduously scaly, soon naked. Fronds ovate-lanceolate, 

 to + 18 cm. long, 6 cm. broad, shortly acuminate, 3-pinnatifld. Pinnae 

 + 18 pair below the pinnatiM apex, subopposite, short-stalked, ascending, 

 contiguous, lanceolate, the lower + 5 cm. long, 2 cm. broad, pinnatifid, 

 serrate at the apex, pinnate in the lower part. Pinnulae parallel, the 

 lower elongate-oval, to 2 cm. long, '/^ cm. broad, subobtuse, very deeply 

 pinnatifid, narrowed at the base, the edges subentire to serrate. Texture 

 coriaceous; surfaces pale-green, giabrescent or provided with scattered, 

 adpressed, fimbriate scales; rachises sparingly scaly, soon naked; veins 

 hidden, simple or forked. Sori in 2 rows on the lobes, often 4 — 6 on 

 a side, submedial or subcostular.

 Suppl., 40, p. p. 



Rhizome wide-creeping, clothed with stifly adpressed, lanceolate, 

 brown scales. Stipes scattered, V2 — I'/a cm. long, narrowly winged, 

 naked. Fronds dimorphous. Barren fronds subcordate or subdeltoid in 

 outline, + 1 — 2 cm. each way, 2-pinnatifid, the rachis narrowly winged 

 hke the stipe, the wings thickened at the edge and therefore 2-sulcate 

 on the upper surface, i. e. the stipe and prominent rachis are separated 

 from the thickened edges of the wings by rather deep grooves. Pinnae 

 close, subimbricate ; higher pinnae erecto-patent, simple, emarginate or 

 bifid, very small, tooth-like, blunt ; central pinnae oblong, + 5 mm. broad, 

 deeply and closely pectinato-pinnatifid ; lowest pinnae horizontal, with the 

 lower pinnulae on the lower side elongated and pinnatifid. Lobes oblong, 

 blunt, the largest l*/j mm. long and 1 mm. broad, or broader but then 

 truncate, emarginate or bifid. Texture very thick and rigid; surfaces
