production of the fronds from a thick crown is concerned ; but these are 

 furnished with pinnules (leafits) as large as those of a good-sized A. cuneatum, 

 of the same peculiar deep green colour, and imbricated (overlapping each 

 other) to such an extent as to warrant the significant popular appellation 

 of " double Maidenhair," under which this variety is generally known. 

 Like A. c. mundulum, it seldom grows more than Sin. high, and is useful for 

 cutting and for edging in Ferneries ; it also possesses the property of 

 reproducing itself true from spores. — Nicholson, Dictionary of Gardening, 

 U P- 27. 



A. c. schizophyllum — schiz-oph-yl'-lum (cut-leaved), Moore. 



Although it is stated that this form appeared in a batch of seedlings 

 of A. mmulum, there is little doubt that it is a variety of A. cuneatum,. 

 Its mode of growth, the production of its fronds from a densely-tufted crown, 

 the shape of its segments, even their peculiar dark green colour, all seem to 

 point to the origin of this plant, of very graceful habit and good constitution. 

 Although dense and stocky in growth, all its parts are small and slender ; 

 its fronds, about 1ft. in length, are furnished with pinnules (leafits) in all 

 cases small but commonly minute, the majority of them being cut into 

 very narrow lobes. The branched character of the fronds is the chief 

 peculiarity of this elegant variety : it causes an irregular development of the 

 leaflets, which are occasionally placed at some distance apart. The sori (spore 

 masses), of a crescent-shape, are situated in the notch at the summit of the 

 pinnule ; but they are sparingly produced in a perfect state, and the variety 

 is usually increased by division of the crown. — Nicholson, Dictionary of 

 Gardening, iv., p. 485. 



A. C. striatum — stric'-tum (upright), Moore. 



A garden variety, of little decorative value, but very interesting through 

 the pinn&3 (leaflets) with which its thrice -divided fronds are furnished being 

 ascending and arranged somewhat spirally. — Nicholson, Dictionary of Gardening, 

 iv., p. 484. 



A. C. Yersaillense — ver-sail-len'-se (from Versailles), Truffaut. 



This exceedingly pretty form, which in size as well as in habit is so 

 equally intermediate between A. c. grandiceps and A. c. Luddemannianum as
