be quickly distinguished from all others by its wedge-shaped pin- 

 nules. It grows fnst, is nearly hardy ; at all events, I have seen it 

 frozen hard in seven degrees of frost, without suffering in the least. 

 Slugs and wood-lice are intensely fond of it. 



A. chiliense. — A very bold-habited species, with large, round, 

 handsome pinnules of a brilliant light green. It is tolerably hardy, 

 and thrives in a cool house. 



A. formosum. — Yery distinct and fine, the stipes conspicuous 

 by their dark colour, the fronds rich green, wide, triangular, each 

 thrice-divided, and each division divided thrice again. Xearly hardy, 

 not easily destroyed, even by several degrees of frost, or by much 

 bad treatment. It makes a sumptuous specimen. 



A.fidvum. — This grows in the style of formosum or affiue ; the 

 young fronds are of a delicate pinky- white colour, then become dull 

 red, and ultimately deep green. It is rather downy, grows 

 vigorously, and is comparatively hardy. 



A. hispidulum. — Common, nearly hardy, graceful, much like the 

 last, both in the colour of the young fronds, and the downy nature 

 of the rachis and stipes. 



A. tenellum. — This is a small, bluish green species, rather spare 

 in habit, but distinct and pretty. It is sometimes (but wrongly) 

 labelled hispidulum. 



A. reniforme. — Undivided, kidney-shaped fronds of great beauty, 

 especially when in fruit. It grows to perfection in a close case, and 

 will do well in the greenhouse under a bell-glass. It has been 

 reported on in these pages as a case fern, and has also been figured. 

 We have a plant now which has been in an unheated case for years. 

 The fronds are of the size of half-a -crown, and bear abundance of 

 fruit. 



A. setulosum. — This has been described and figured in these 

 pages. It is a perfect gem, especially to grow in a basket, or cocoa- 

 nut husk. If there are orifices all over the receptacle, the plant will 

 push through, and soon cover it with its light green three to five 

 divided fronds. In some respects it may be called a small edition 

 of afiine. 



A. tinctum. — Light and elegant in habit, the divisions similar to 

 assimile ; or it may be called a large edition of capillus veneris. 

 The young fronds are of a delicate rose colour, changing to dull 

 purplish red, and afterwards to delicate green. As a case fern it is 

 unsurpassed, and as a greenhouse fern is comparatively hardy, and a 

 good grower. I have the original plant presented to me by Messrs. 

 Yeitch when the species was first introduced, and it is now a superb 

 specimen. 



ADIANTUMS ADAPTED FOB CASES. 



Amongst the foregoing, the following are admirably adapted for 

 closed cases : — Capillus veneris, assimile, affine, cuneatum, chiliense, 

 formosum, fulvum, hispidulum, tenellum, reniforme, setulosum, 

 tinctum. 



The species that require the stove must be noticed next month.
