﻿54. ATHYRIUM. 4^9 



plenium toppingianum, Copel., Polypod. Philipp., 80; — var. mixtum {mistum), 

 Copel., 1. c. ; Asp. Toppingii, Copel., MS. in Herb. Bog. 



Rhizome creeping, chaffy, the scales lanceolate, pale-brown. Stipes 3 — 10 

 c M. long, scattered, the base brown and chaffy, upward becoming green and 

 naked like the rachis Fronds 10— IS c.M. long, % — 2 '/j c.M. broad, the upper 

 half deeply pinnatifid with several erecto-patent, oblong, blunt lobes, the apex 

 toothed to crenate, acuminate, the lower half simply pinnate with + 6 pinnae 

 on each side. Pinnae oblong, blunt, serrato-crenate, auricled at the base on 

 the upper side. Texture herbaceous, rather firm; surfaces naked; main rachis 

 narrowly winged towards the upper half of the frond. Sori short, straight, 

 curved, or some of Ihem horseshoe-shaped, the lower sometimes double. 



Wa.1*. niixtani: Larger; teeth of the pinnae more rounded ; the lowest 

 pair of pinnae more than 2 X the dimensions, deeply incised.

 gedeanum, Rac, Flor. Btz., I, 223. 



Rhizome erect or suberect, densely clothed with brown, lanceolate scales. 

 Stipes firm, erecl, 10— 50 c.M. long, stramineous, glossy, scaly, at the base. 

 Fronds oblong- or lanceolate-deltoid, 15 — 50 c.M. long, 5 — 15 c.M. broad, the 

 apex acuminate, toothed to deeply pinnalifid. Lateral pinnae 10—30 on each 

 side, linear to lanceolate, the higher ones sessile, the lower ones distant', sub- 

 sessile, ± deflexed, often shorter than the next in order, the longest ones 

 spreading, 5 — 10 m.M. broad, the apex acute or blunt, sometimes acuminate, 

 the upper base truncate or broadly cuneate, often auricled, the lower base 

 cuneate, often slightly auricled, the edge slightly lobed, the lobes sharply toothed. 

 Texture coriaceous; main veins pinnate in the lobes. Sori short, mostly close 

 to the midribs, rarely diplazioid at the apex.
