J-f in. 1. 2-4 li. w., subdistant or distant., ovate or lanceolate, acute- 

 blunt pointed or rounded, cuneate-stipitate, sharply dentate, veins pin- 

 nate, simple or forked,, sori copious, 1-2 li. 1. occupying most of the 

 veins, inferior double ; involucres dark brownish. — Hook, 2nd Cent.. 

 Ferns, t. 27. A. diminution, Baker. Jenm. in Journ. Bot. 1881, p. 53. 



Infrequent, gathered in St. George, Portland, on the sides of wet, 

 dripping, calcareous rocks. At about 2,000 ft. alt , in shade. Marked 

 by the lax arrangement of pinnae and pinnulae. the latter and final seg- 

 ments all being sharply toothed or inciso-dentate. Only the largest 

 fronds are tripinnate and only at the base. The specimens first dis- 

 covered, and figured by Hooker were very small. 



52. A. Franconis, Mett. — Rootstock short, erect, clothed with large, 

 blackish lanceolate scales ; stipites caespitose, 1J-2 ft. 1. strong, the base 

 black and paleaceous, stramineous upwards and naked ; rachis similar, 

 flexuose , fronds tripinnate, ovate-acuminate, 2-3ft. 1. 1^-2 ft. w. not 

 reduced at the base, chartaceous. naked, pellucid, light green and glossy 

 paler beneath, pinnae spreading petiolate, ft. 1. 3-5 in. w. pinnulae 



lanceolate, stipitate, deeper on the superior side, shortly cut away on the 

 under, 2-3 in. 1. f-1 in. w. serrate- acuminate, cut within into ovate or 

 oblong blunt or rounded dentate free segments w r hich are 4-7 li. 1. and 

 1J-3 li. w, veins pinnate in the segments, simple or forked, sori copious, 

 oblique, 1^-2 li. 1. bright brown, occupying most of the veins, the in- 

 ferior double ; involucres silvery. — Gr. Fl. B. W. I I. p. 687. 



Frequent in moist woods from the low r er valleys up to 2,500 ft. alt. 

 The barren state, in which it is often found, much resembles Davallia 

 incequalis, and is difficult to distinguish. The pinnae and pinnulae are 

 rather distant, the tertiary segments close and compact. The underside 

 of fertile fronds have a very beautiful aureous tinge from the blended 

 colours of the surface, involucres and sori. The Jamaica form is more 

 compound than the continental. 



'53. A. conchatum, Moore.— Rootstock short, erect, clothed at the top with 

 large lanceolate or ovate lanceolate dark scales ; stipites caespitose erect, 

 1 2 _ 2 i ft. 1. paleaceous at the derk base, glabrescent, channelled, light or 

 dark brown, rachis similar ; fronds erect, bipinnatifid, hardly narrowed 

 at the base, acuminate, 2^-4 ft. 1. 1-1 J ft. w. chartaceous, pellucid, dark 

 green, glabrescent, pinnae numerous, spreading obliquely or horizontally, 

 oblong-lanceolate, acuminate, 6-10 in. 1 1^-2 in w. close or more or 

 less distant, shortly petiolate, pinnatifid to the narrow wing of the costa, 

 apex serrate-acuminate ; segments linear-oblong, f-1 in. 1. 2-3 li. w. 

 horizontal, blunt or rounded, rarely acute, more or less serrated, close or 

 apart, the sinuses sharp or open, rounded; veins simple or forked ; pel- 

 lucid ; sori ^-f li. 1. close to the midrib, the inferior double ; involucres 

 firm, persistent, dark, vaulted. — Hypochlamys pectinata, Fee. 



a. Yar. Tussacii. — Segments J in. 1. 1-2 li. w. round pointed, even 

 or faintly serrulate, sinus open, rounded, sori J li. 1. Hypochlamys 

 Tussacii, Fee Fil. Ant. t. 9 fig 1. 



b. Yar. squamidosxm. — Pinnae almost or quite pinnate at the base, 

 segments with a wide open sinus between, deeply lobate-dentate. — Eypo- 

 chlamys squamulosam, Fee Fil. Ant. t. 9 fig. 2. 



Common near streams in forests and shady places from 1,500-4,000 

 ft. alt. The sori are very variable in the different forms, usually short, 

 but in some cases reaching nearly to the margin, the involucres being
