Sikkim; Yakla Pass, alt. 12,000 feet, W. S. Atkinson.—Distrib. Mandchuria. 
Lowest pinnz longest, subopposite. Primary pinn: in outline lanceolate, narrower 
at the base; secondary pinnæ narrow-oblong acute, not narrower at the base. Involucre 
very small and thin.—Maximowicz, in his description, states that the sori are lateral 
(as they distinctly are in this species); it is therefore not clear why Maximowicz called 
the plant a Cystopteris. Beddome’s picture shows the tertiary pinnz confluent, so that 
the frond is 2-pinnate ; in all the Kew examples the tertiary pinne stand rather wide 
apart, but they are sessile, and the rhachis of the secondary pinne narrowly subulate 
by their decurrence. 
Var. subtriangularis, (sp.) Hk. & Baker, Syn. Fil. 225. Tertiary pinne crenate serrate. 
_ Sikkim, alt. 10,000-12,000 feet; Lachen, Samding, Yeumtong, Sir J. D. Hooker.— 
I can find no difference between this and .4. spinulosum type, except that the teeth 
are much less spinulose, sometimes hardly acute. 
28. A. ATKINSONI, C. B. Clarke. Frond 10-12 in., deltoid, as broad as long, 3-pinnate, 
4-pinnatifid; veins terminating just within the margin.—Athyrium Atkinsoni, Bedd. 
Ferns Brit. Ind. Suppl. p. 11, t. 359. 
Sikkim, at high levels, W. S. Atkinson. : 
Stipes 6-12 in., straw-coloured, with a few long, narrow, pale scales near the base. 
Pinne 7-8 on each side, texture herbaceous, lowest much the largest, 6 by 3 in. 
Involucres subquadrate, i.e. hardly longer than broad.— The above is drawn entirely from 
Col. Beddome's figure and description. I must have been with W. 8. Atkinson when he 
collected this plant; but none of my alpine Sikkim Athyriums agrees with Col. Beddome’s 
figure. I suspect that figure is from a small specimen of the following. 
Var. Andersoni. Frond 9-27 in., 4-pinnate, 5-pinnatifid. (Pl. LVIL) 
Sikkim, alt. 9000-12,000 feet, Tonglo and Singalelah, Dr. Jerdon, C. B. Clarke.— 
Stipes solitary. Rhachis red, wavy, slightly scaly, and glandular-rugose. Texture 
rigid. Lowest pinne often 14 in.; lowest secondary pinnz shorter than those above 
them. No gland at the bases of the primary pinnz. Sori somewhat large ultimately, 
nearly covering the quaternary pinnz, which are }-3 in., short-oblong, bluntly crenate- 
pinnatifid halfway to the midrib. 
** Stipes tufted or approximate. SC | 
29. A. DREPANOPHYLLUM, Hk. & Baker, Syn. Fil. (2nd ed.) 226. Frond linear, narrowed 
to both ends; pinne numerous, l-l} by 1-4 in. subentire, pinnatifid halfway 
down, or at the base cut down nearly to the midrib into short-oblong subobtuse 
lobes ; involucres, when young, linear or linear-oblong.— Athyrium falcatum, Bedd.

Stipe 1-9 in., with many linear reddish scales at the base. 
Sometimes 15-20 on each side the main rhachis. Lobes entire,
