is grown in a basket and suspended from the roof of a warm house. A 

 distinctive character peculiar to this species lies in the disposition of the 

 lowest pinnules, for these are upright and pressed flat against the stalk, 

 which they cover almost on its entire length. See Plate.— Hooker, Species 

 Filicum, ii., p. 42. Nicholson, Dictionary of Gardening, L, p. 25. Lowe, 

 Ferns British and Exotic, iii., t. 1. 



A. c. Fleming! — Flem-ing'-i (Fleming's), Moore. 



A very grand variety, of garden origin. It is of a more upright habit 

 and is not adapted for growing in hanging baskets ; the fronds, which are 

 shorter, but denser and produced in greater abundance than in the type, 

 partake of the same light green colour, and have a very pleasing pinkish 

 hue when young. — Nicholson, Dictionary of Gardening, L, p. 25. 



A. C. latum — la'-tum (broad), Moore. 



This is a most valuable and distinct stove Adiantum, native of the East 

 Indies, and recognised as being a form of A. concinnum, from which it 

 essentially differs by its stiff, upright habit, and by the size of its pinnules 

 (leafits), which are twice as large as those of that species and set much 

 farther apart. See Fig. 35. — Nicholson, Dictionary of Gardening, ii., p. 25. 



A. COnYOlutum — con-vol-u'-tum (wrapped together), Fournier. 



A stove species, of Mexican origin, having a very distinct appearance on 

 account of the disposition of the pinnse (leaflets) on longer stalks than those 

 of most Adiantums. The fronds are quadripinnate (four times divided to the 

 midrib), about lft. in length, and their long-stalked leaflets are of two 

 different characters, the lowest ones being decompound (subdivided) and the 

 upper ones lanceolate (spear-shaped) and simply pinnate (only once divided 

 to the midrib). The terminal segment is cuneate-fiabellate (wedge-shaped at 

 the base and fan-shaped at the summit). The sori (spore masses), which are 

 disposed two to four to a segment, distinguish this plant from all the other 

 species of the group by their greater size, as they frequently measure two 

 or two and a-half lines in breadth. — Hooker, Synopsis Filicum, p. 474. 



A. COrnubiense — cor-nu-bi-en'-se (Cornish). This is merely a form of 

 A. Capillus- Veneris.
