impellucidae, partim pellucidae. Sori a margine remoti; capsulae 6—8. 

 obscure brunneae. 



A. pruinosa Kze differs in having the largest pinnulae with the base 

 distinctly rotundate-cordate, the sori submarginal, the capsules more 

 numerous, mostly 9 — 10. 



Java (ML Gede, A. Swartz No. 2637). 



Angiopteris leytensis, v. A. V.R. 



A. pruinosae Kze affinis sed pinnulis maximis vel inferioribus basi 

 truncato-rotundatis vel rotundato-cuneatiS; indusio sororum déficiente vel 

 obsoletissimo, capsulis + 4 — 8. 



A. pruinosa Kze differs in having the largest or lower pinnulae 

 unequally or subequally cordate at the base, the indusium very distinct, 

 consisting of ferrugineous hairs or fibres, the capsules +8 — 16, mostly 9 — 10. 



Forma typica: Pinnulae distinctly crenulate, often subabruptly acuminate; 

 sori contiguous. — Le;^^e {Palo, A. D. E. Elmer No. 7064; received as A. 

 longifolia H. & G.). 



Forma negrosensis : Pinnulae partly entire, partly irregularly repando- 

 crenulate or -serrulate, often very gradually acuminate ; sori often somewhat 

 spaced. — Negros (Dumaguete, A. D.E. Elmer No. 10275; received as A. 

 pruinosa Kze). 



Angiopteris ceracea, v. A. v. R. 



A. pruinosae /("ze affinis sed pinnulis majoribus, maximis minime 15 — 25 

 cm. longis, 2—3 cm, latis, subtus saepe viridulo-(raro caerulescenti- vel 

 purpurascenti-)pruinosis; soris a margine remotis. 



A. pruinosa Kze has the pinnulae much smaller, the sori nearer the 

 margin. 



A. large fern with the fronds 4—6 m high including the stipe. 

 Malay name „pakoe gadjah" (= elephant fern).

Angiopteris javanica, Pr., Tent. Pterid., Supplem., 20; A. Dregeana, 

 de Vr., Mon. Maratt., 17, tab. Ill — IV, fig. 8; A. Brownii,v .A.v .R 

 A. cordata, v. A. V.R., MS. 



Forma typica: Leaflets 12'/2 — 17'/2 cm. long, 1 '/4 — l^A (rarely to 2) 

 cm. broad, the apex mostly subabruptly acuminate, serrulate, the base 

 generally subobliquely truncate- to rotundate-cordate with no deep sinus; 

 sori consisting of 6 — 10 (mostly 8 — 9) capsules. A. — Hartingeana de V^r. is 

 probably but a form of this, with a more rotundate-cuneate base and more 

 copious capsules. — Java, Sumatra, Philippines. 



Forma Brownii: Like the type but the leaflets with the base conspic- 

 uously cordate, the acumen repando-crenulate, and the sori reaching nearly
