.he apex ; pinnl linear-oblong, \ in, 1., little more than 2 lines br., pinnatifid 

 ivithin a short distance of the rachis into numerous linear lohes ; texture her- 

 baceous ; rachis and under surface glanduloso-pilose ; sori 2 to IG to a pinnule, 

 placed at the base of the sinuses ; invol. cup-shaped, globose, J line across.— i/>t.

Hab. Nepaul and Kumaon.— This and the preceding resemble in hi\\Ai Athyrium 

 iUx-fcemina. Species 13 to 29, except 17, fall under the genus Sltolohium of /. Smith, 

 and have creeping rhizomes. 



Gen. 14. Deparia, Hook. & Grev. (See p. 4G3.) 



Sori protruded from the margin of the frond, or even stipitate. Invol. shal- 

 lowly-cu].shaped, membranaceous, not 2-valved.— T/;rce veri/ rare tropical species 

 with broad, ample leafy segments, lohich differ from Dennstsedia mairdi/ by their extra- 

 mat^inal sori. Veins anastmnosing in one of the species (Cionidium, Moore). 



1. T>. j>rolifera, Hlc. ; fr. once fully pinnate; lower pinnae about 6-9 in. 1., 

 i-li in. br., pinnatifid down throughout within a short distance of the rachis ; 

 lohes oblong, slightly toothed, with often a space equalling their breadth between 

 them ; lettered veins' oi the lobes all simple ; texture herbaceous ; sori 4 to 12 to 

 a lobe, extra-marginal, sessile or stipitate.— i^/t. Sj). Fil. I. p. 85 ; Fil.Exot. t. 82.

Hab. Sandwich Islands. 



2. D. concinna, Baker ; fr. twice pinnate ; loioer pinnce more than 1 ft. 1., 

 nearly 2 in. br., cut down to the rachis in the lower part, but becoming nearly 

 entire towards the apex ; lohes blunt, entire, broadly oblong-rhomboidal, unefiual- 

 sided and decurrent downwards ; lateral reins of the lobes once or twice branched ; 

 texture subcoriaceous ; sori 2 to 6 to a lobe, jjlaced round the outer edge. — Davallia 

 concinna, Presl. Hk. Sp. Fil. 1. p. 74. Deparia Mattliewsii, Hk. Sp. Fil. 1.

Hab. Peru, gathered by MaUhetvs and Spruce. — This resembles closely DicJcsonia 

 adiantoides in habit. It has the lower part of the sori included within the margin, and 

 is placed by Moore in Dermstcedia. 



3. D. Moorei, Hk. ; /;•. 12-18 in. 1., 6-9 in. br., cordate-deltoid in general out- 

 line, pinnate below, pinnatifid only above ; lower pinnce G-9 in. 1., 4-G in. br., cut 

 down to the rachis below into deeply-pinnatifid broadly-toothed lobes ; veins 

 anastomosing ; texture thinly herbaceous ; sori copious, extra-marginal or stipi- 

 tate. — Hk. Exot. Ferns, t. 28. Cionidium, T. Moore, Trichocarpa, J. Smith. 



Hab. New Caledonia, gathered by C. Moore and Zenormand. — A much smaller plant 

 than the others, with thin, broad, leafy fronds and anastomosing venation. 



Tribe III. IIymenophylleje {including Loxsoma). 



Sori terminal or marginal from the apex of a vein. Recept. elongated, often fili- 

 form and long, and exseHed more or less, especially below clothed with sessile m'hicular 

 imhricated subpeltate compressed capsules, surrounded by a complete transverse ring, 

 opening vertically. Invol. inferior, various in shape, generally of the same texture as 

 the frond. Small often epiphytal Ferns, herbaceo-memhranaceous, more or less laxly 

 cellular, variously costate and veined. Caudex frequently long-creeping, and filiform. 

 {In Loxsoma the oblique ring of the suhpedicellate capsule is incomplete ; thefrondg 

 arc coriaceot'S.) Gen. 15-17.
