O ADIANTUM. 



founded with (not taken for) Lindseea macrophylla. The one {A. dolosimi) 

 has a reticulated venation, the other {A. Phylktidis) has not. 



9. A. Wilsoni, n. sp. ; frond ovate pinnate, pinnae 3 — 7 

 alternate petiolate large ovate-acuminate (sterile ones sharply 

 and irregularly serrated) coriaceous dark green above paler 

 and slightly glaucous beneath, both the margins at the base 

 more or less rounded but the sides unequal not cuneate, costa 

 distinct and ebeneous at the base, veins forked here and there 

 anastomosing, sori continuous on both margins and nearly to 

 the apex, stipes and rachis ebeneous glabrous. (Tab. 

 LXXII. A.) 



Hab. Shady, rather dry and gravelly places near Bath, Jamaica, 

 Mr. Wilson. — I name this species in compliment to Mr. Wilson, the in- 

 telligent Curator of the Bath Botanic Garden, Jamaica, from whom Mr. 

 Smith and myself have received dried specimens as well as living ones, 

 which latter are growing and fructifying vigorously in the stoves of the 

 Royal Gardens. Although very distinct as a species, it seems to hold an 

 intermediate rank between A. Phijllitidis of J. Sm. and the A. dolosum, 

 Kze. Its stipes and rachis are glabrous, the surface of the pinnae is nearly 

 as smooth and even as in the former, but occasionally the veins are slightly 

 prominent. In the partial anastomosing of the veins the species approaches 

 the latter : from both it is at once known by the broader and greener pin- 

 nee, and the more rounded and more equal sides at the base. In cultiva- 

 tion the young fronds are sometimes seen quite simple, cordate, and finely 

 but unequally serrated, as represented at our fig. 1. of Tab. LXXII. A. l".

10. A. dolosum, Kze. ; frond ovate pinnate (very rarely 

 subbipinnate below), pinn® alternate very short-petioled sub- 

 coriaceo-chartaceous olive brown and slightly glossy when 

 dry large lanceolate or elliptical-lanceolate very much acu- 

 minate almost caudate often falcate sterile portion serrulate, 

 costa ebeneous at the base, the upper margin at the base 

 rounded or truncated the lower one cuneate, veins everywhere 

 anastomosing and prominent on the upper side in the dry 

 state, terminal pinna the largest, sori continuous on both 

 margins but leaving the much acuminated apex sterile, stipes 

 and rachis ebeneous the latter especially slightly scabrous 

 with rufous hairs. (Tab. LXXIX. B.) — Kze. in Linnxca, xxi.
