spores in tMs country, unless it be of L. retusa of Mettenius, which has been 

 fully described as Davallia retusa^ the name first given to it by Cavanilles, 

 subsequently confirmed by T. Moore, and under which the plant is also 

 extensively known in European gardens. 



Principal Species and Varieties, 



L. adiantoides — ad-i-ant-6-i'-des (Adiantum-like), /. Smith. 



A species of medium or small dimensions, also known as L. humil/s, 

 native of the Malayan Archipelago. Its elegant fronds, 4in. to 6in. long, 

 lin. broad, and simply ]3innate (only once divided to the midrib), are borne 

 on somewhat tufted, black, polished stalks lin. to 2in. long and of a wiry 

 nature. The leaflets, of a soft, papery, and somewhat transj)arent texture, 

 are about Jin. long and Jin. broad, with the upper edge rounded and broadly 

 lobed about one-third of the way down, and the lower one straight or slightly 

 curved. The sori (spore masses) are marginal in the lobes. — Hooker, SjJecies 

 Filicum, i., p. 204, t. 61c. Nicholson, Dictionary of Gardening, ii., p. 280. 



L. borneensis — bor-ne-en'-sis (Bornean), [looker. 



This species, with short- creeping rhizome and fronds 1ft. to l^it. long 

 and 9in. to 12in. broad, is a native of the forests of Borneo. It comes very 

 near the better -known L. guianensis, but its sori are quite marginal and 

 disposed in a continuous line. — Hooker, Synopsis Filicwm, p. 107. 



L. botrychioides — bot-rych-i-o-i'-des (Botrychium-like), St. Elilaire. 



A Brazilian Fern, which it is suggested may be simply a loose, 

 unbranched variety of L. guianensis, but smaller in all respects, and with 

 fronds simply pinnate (only once divided to the midrib). The sori (spore 

 masses) are disposed in a continuous line round the upper and outer edge and 

 the inner half of the lower one, the outer valve projecting beyond the inner 

 one. — Hooker, SyjiojJsis Filicum, p. 105. 



L. Catherinae — Cath-er-i'-na; (from St. Catherine's), Hooker. 



Although Hooker, in his " Species Filicum " (p. 212, vol. i.), minutely 

 describes as a species and gives an illustration (t. 65b) of this Brazilian
