44 6. ALSOPHILA. 



Hab. Java, Bl. in Herb, nostr. (but sterile), and Celebes. I possess what I consider 

 quite another plant, with menibranaceous fronds, and quite free from scales beneath, ex- 

 cept i few minute, widely scattered bullate ones, from Dr. Miquel, under the name, from 

 Java, and what I believe to be the same also, but quite destitute of bullate scales, from 

 Mr. Parish, Moulmein ; both in too imperfect a state to merit further notice. 



61. A. crenulata, Mett. ; "fr. bipinnate (or 3-pinnatifid) submembranaceous, 

 beneath bullato-squamulose on the costse ; pinnl. lanceolate, acuminate, deeply 

 pinnatifid ; segm. linear-oblong, obtuse, serrulate ; sori (1-4) near the base of the 

 costules ; rachises tomentose above, asperulous beneath ; caud. arboreous." 

 BL En. Fil. Jav.p. 246, under A Is. extensa, excl. Syn. (Mett.'). 



Hab. Java, Blume in Hb. nostr. Some Indian AlsopUlce, in my Herbarium, I am 

 unable to refer to any known species, nor are the specimens sufficiently perfect to justify 

 me in describing them. 



62. A. tristis, Bl. ; st. as thick as a goose-quill, 2 ft. 1. and more, dark purple, 

 glossy, and as well as the main rachis (oi the same colour) tuberculato-asperous ; 



fr. siibcoriaceous, blackish-brown when dry, ovato-lanceolate, S ft. 1. and more, 

 tripinnate ; prim, pinnce distant (3-4 in. apart below), 1 ft. 1., often 4 in. w., 

 ovato-lanceolate, much acuminated ; secund. pinnce 2-3 in. ]., oblong-acuminate ; 

 ultimate pinnl. sessile, 3-5 lines 1., oblong-obtuse, inciso-pinriatind about half-way 

 to the co >tule ; upper portion of the main rachis, the secund. rachises, and costa espe- 

 cially beneath, furfuraceo-hirsute ; veins pinnated in the ultimate pinnules ; sori 

 large, one to each lobule ; capsules, when young, apparently agglutinated, close- 

 pressed ; receptacle elevated. Alsophila tristis, Bl. in Hb. nostr. Cystopteris, 

 Metten. in Hb. nostr. 



Hab. Java, Blume, Millett, De Vriese. A very remarkable Fern, with much of the 

 general aspect of Diacalpe. 1 find no trace of an involucre ; yet Mettenius has referred 

 it to Cystopleris. I possess from Blume apparently a pinnule of another Java Fern, 

 somewhat allied to this, under the name of Alsophila tenuisecta, which also I cannot find 

 described : the fragment is 4 in. 1. and 1| in. w., bipinnate, dark olive-brown ; ultimate 

 segm. 2 lines 1., oblong-obtuse, sessile, pinnatifido -serrate, laxly villous, as is the pale 

 rachis ; veins pinnated ; one small sorus on the superior basal vein, of few capsules. It 

 is probably a Phegoptcris. 



63. A. subglandulosa, Hance ; st. densely clothed at the base with long flaccid 

 linear light-brown scales ; fr. ample, tripinnate ; lower pinnce 1 ft. 1. ; pinnules 

 lanceolate pinnatifid, the lower segments cut down nearly to the rachis, ciliated 

 at the edge with glandular hairs ; the lateral veins once forked ; prim, and secund. 

 rachises densely clothed with small linear dark^coloured scales, texture herba- 

 ceous ; sori copious. 



Hab. Island of Formosa, gathered by the late Mr. Oldham. Our specimens have the 

 fronds about 2 ft. 1. by 1 ft. br.

64. A, JZthiopica, Welw, msc., Hk. ; caud. 3-6 ft. 1., 2-3 in. w., knotted with 

 large tubercles, the cicatrices of the fallen stipites ; st. thick as a goose-quill, 

 a span and more long, asperous with small tubercles, nearly smooth on the main 

 rachis, purplish on the upper side ; fronds firm-membranaceous, dark green, 4 ft. 

 and more I., broad-lanceolate, quite glabrous, except on the costee and costules, 

 which are hairy on both sides, pinnated ; pinnce 8-10 in. ]., subsessile, oblong- 

 acuminate, pinnated below, the rest deeply pinnatifid with lobes f in. 1., oblong- 

 sublanceolate, scarcely falcate, acute, more or Jess coarsely serrated ; veins forked ; 

 sori at the forks, copious, rather nearer the costule than the margin, orbicular 

 compact. A. Ourrori, Hk., Met. 



Hab. Tropical Africa, S. of the Line, Dr. Curror ; Angola, Golungo alto, alt. 1,000- 

 2,400 ft., Welwitsch, n. 116 and 116 2 . A very peculiar and well-marked species.
