small, very coriaceous fronds, very dark-green above, whitish and densely scaly 
beneath, remain expanded or curled up through the winter and succeeding hot 
dry weather, — uncurling when the rainy season sets in. Then, much larger, 
herbaceous, fronds spring up, the cutting and colour of which is at first very 
beautiful ; and in the Autumn very large fronds are found, with a coarser 
cutting, which wither light- brown or yellow, and seem to have a greater 
proportion of lamina, and are almost membranous in texture. Fronds quite 
similar to these last, though smaller, are found in C.rvfa. I do not know when 
the small coriaceous persistent fronds (described above) found remaining the 
next season spring up. I have never seen powder approaching to yellow on this 
fern, but always pure white, though not very dense. Fronds, especially the late, 
large, ones, are often found without powder ; but Mr. Baker is wrong in de- 
scribing the fern as “ denuded,”— if he means denuded of white powder. 
Of this species Blanford says — “ very abundant in and around Simla, cover- 
ing the roadside banks and old stone retaining walls. Bange from 4800' 
(my lowest) up to 8500', above which it is replaced by C. Ddlhousm. The 
following is a description of C . albo-marginata , which is well represented in the 
figure, Plate 52, of Clarke’s Review, except that the scaliness of the costae and 
veins is not fully shown. 
“ Stipes 4 to 10 ins. long, generally shorter than the frond, bearing 
throughout dark linear lanceolate scales with pale translucent margins. 
Similar scales extend to the primary, and secondary rhachises and costm. 
Fronds up to 4 Finches long, acute deltoid, under-surface naked, or in 
the youDg state and in the small fronds that persist through the dry 
season, thinly coated with yellowish-white powder. Lowest pair of 
pinnae generally the longest. Segments oblong. Lines of sori scarcely 
interrupted at the sinus. Margins of involucres highly lacerate. 
** It is always readily distinguishable from the other allied forms by the 
presence of scales on the veins and costm, and by the highly lacerate 
involucres.”
