 on the rhizome also vary extremely in length and colour. 



Gen. XXVI. GYMNOGRAMMA, Desv. 



Sori nudi, lineares, dorso venamm venularamque siti, demum confluentes. Vena furcate, liberse.— 

 Ehizoma brevissimwm v. nullum. Frondes caspitosa , pinnata v. U-tripinnata. 



Principally tropical Ferns, with (rarely simple) pinnate, bi-tri-pirmate, tufted fronds, having no rhizome or a very 

 short one.-Son naked, linear, occupying the veins and venules, hence often running in lines and forking • also 

 covering the spaces between the veins and then becoming confluent. (Name from W vo S , naked, and ™, a 

 line; in allusion to the linear sorus, which has no indusium.)

Hab. Northern Island ; East Coast, Colenso. 



This little plant is abundant in extra-tropical Australia and Tasmania, and has also been gathered in the 

 Pyrenees- but I know of no other countries which it inhabits.-JWs densely tufted, 3-5 inches long villous 

 often glandular, pinnate ; roots of numerous tufted fibres. Pinna 2-5 lines long, alternate, distant, shortly stipitate' 

 cuneate or flabellate, more or less incised or lobed, rarely quite entire. Sori linear, scattered, often confluent.

Hab. Dry bills on the East Coast, Colenso, Sinclair. (Cultivated at Kev.) 

 _ This beautiful little Pern is remarkable for its wide geographical distribution in the northern hemisphere • it 

 inhabits Jersey, the Mediterranean shores and the Atlantic islands, Abyssinia, Mexico, and the Himalaya mountains 

 In the southern, besides New Zealand, it grows in Tasmania, East and West Australia, and the Cape of Good 

 Rope-Fronds an inch to a span high, perfectly glabrous, membranous and shining, pale green, oblong lanceolate 

 bi-tri-pmnatifid. Pinnules 2-4 lines long, obovate-euneate, twice or thrice lobed or erenate, the lobes blunt'

Sorus linearis, continmis v. interrupts, marginatum nudus v. sub margine pinnulae inflexo nidulans.— 

 Vena libera, pinnate v. furcate.— Rhizoma brevissimum. Erondes erect*, rigida, caspitosa, plerumque 

 farinosa, squamosa v. tomentosa, pinnate v. bi-tri-pinnata. 



A tropical and subtropical genus, of which the only New Zealand species is also a native of Australia and New 

 Caledonia. This very closely resembles Cheilantlies tenuifolia, but may be readily distinguished by its scaly and 

 tomentose frond, and by the confluent sori not being covered by any special involucre.— Fronds of N distans 

 densely tufted, arising from a very short rhizome, 3-10 inches high, rigid, wiry, erect, scaly with long pale scales' 

 linear, bipinnate, or pinnate, with the pinnas pinnatifid. Primary pinnce distant, deltoid, shortly stipitate hirsute 

 below with pale shaggy scales, pubescent or naked above; pinnules short, oblong. Faclis and slender stipes
