Very common in shady and open places in coffee plantations and 

 forests trailing over rocks and decaying logs from 1,000-3,000 or 4,000 

 ft. alt. The fronds part at the articulation, and drop, leaving the base 

 of the stipe adherent to the rootstock. In this the rootstock is hori- 

 zontal in growth, while in the other American species, O. neriiformis, 

 Cav. it is erect with the joint of the petioles at the base, and with 

 smooth or hairy surfaces. 



Genus XXIX. Fadyenia, Hook. 



Fronds acaulose, entire, dimorphous, veins areolated ; receptacles 

 oblong, on free included veinlets ; sori large, deeper than broad, ob- 

 long-reniform, with a deep sinus and converging auricles ; involucres 

 ample, attached interiorly, the exterior edge free. 



A monotypic genus, found only in Jamaica and Cuba. The sori 

 are several times larger than in any other genus of the Tribe, being 

 1^-2 1. 1. by 1^ 1. w., doubled in 'the form of a horse shoe, on an elon- 

 gated receptacle, the folded ends converging almost together at the 

 base. Occasionally the. veinlet extends beyong the sorus to the other 

 side of the mesh. 



F. prolifera, Hook. — Rootstock small, fibrous-rooted, fronds simple, 

 entire, csespitose with hardly any distinct stipites, fibrillose at the ta- 

 pering base ; barren prostrate, narrowed both ways from the centre, 

 outwards into a much elongated tapering tail proliferous and rooting 

 at the summit, f-1 in. w., 3-7 in. 1. ; fertile erect, oblanceolate, rounded 

 at the summit, narrowed in the sterile lower half to the long-tapering 

 base, 4-6 in. 1. -4-5 li. w. ; both fronds nuked, 'dark-green ; membrano- 

 chartaceous ; costal areola large, exterior smaller with free branches 

 along the margins ; sori unserial between the midrib and edge, usually 

 confined to the costal meshes ; involucres persistent, at length shrivell- 

 ing. SI. t. 25. f. 1. Hook. & Grev. Ic. t. 96. Hook. Jen. t. 53. B. 

 Hook. Frl. Exot. t. 36. Asplenium, Sw. Aspidium, 1 Mett. 



Infrequent on the wet banks in the eastern parishes up to 2,0u0 ft. 

 altitude. In the barren fronds it resembles Asmdium rhiokphyUumi 

 The earlier fronds are oblanceolated ; the next rather ovate-lanceolate, 

 extending into a much-elongated winged tail a line or' less wide 

 at the radicant summit. In the fertile this is reversed ; they taper 

 similarly, but inwards to the base, and Only the broader outer part is 

 fertile. Occasionally an odd reduced sortis is produced in one of the 

 smaller outer meshes. Most of the space between the midrib and 

 margin is taken up by the sori, which run more or less parallel there- 

 with.
