surface of the frond more or less scaly; pinnsz very close together, auriculate, 
falcate, not lobed, coriaceous, shining, spinulose serrate; sori mostly in two rows; 
involucre denticulate on the margin.—Schk. Krypt. Gew. t. 29; Hook. Brit. Ferns,

The single Himalayan specimen at Kew (Jacquemont’s) has been marked 4. Lonchitis 
by Moore; but others have marked it 4. auriculatum. H. C. Levinge’s example is 
typical A. Lonchitis. 
2. A. LACHENENSE, Hook. Sp. Fil. iv. 8, t. 212. Frond narrowly linear, 1-pinnate ; 
stipe long, thick, chestnut-coloured, somewhat succulent; pinnze 3j in., ovate or 
ovate-oblong, entire or pinnatifid halfway down, scarcely coriaceous, margin crenate- 
serrate, scarcely spinulose; sori 6-10 to a pinna ; involucre slightly denticulate.—

Rhizome very scaly; stipes very numerous, thick, rising in a dinge: mass.  Frondin 
the typical specimens 5 by less than 3 in., the lower pinnz remote, but soriferous and 
hardly reduced. Stipe scaly, as is the kond beneath more or less. My Kashmir 
specimen agrees closely.—There are several loose fronds and scraps of fronds collected 
by Jerdon placed together here; if they were cut from one rhizome, they indicate a 
passage from 4. Lachenense to A. ilicifolium, Don. 
9. A. ATKINSONI, C. B. Clarke. Frond small, linear, 1-pinnate, the base not attenuate ; 
stipes thin; pinnæ j-1 in., ovate, entire, coriaceous, sparingly denticulate, sub- 
spinulose ; sori 1-3 to each pinna; involucre slightly lobulate. Polystichum

Col. Beddome's picture is rather larger than my examples, which have, some of them, 
the frond in good fruit 1 in. long only. This fern has a small rhizome and slender stipes 
about as long as the frond, and thus (as well as by its very coriaceous texture) differs 
considerably from 4. Lachenense ; W.S. Atkinson originally called it Polystichum ilici- 
folium, var. minus and minimum. The rhachis is somewhat scaly, the surface of the frond 
beneath but very slightly so (in my examples). 
4. A. AURICULATUM, Swartz, Syn. Fil. 44. Frond linear or linear-lanceolate, 1-pinnate, 
not attenuated at the base; stipe and lower surface of the frond more or less scaly ;
