smooth to shining below; costae* flattened on the under side, 
naked or with reduced scales, the surface never araneous; veins 
not raised below, the vein spaces 10-14 to I cm. Sporophyls (in 
the only complete one seen) 110 cm. long; stipes 30-40 cm. long, 
marked at least part way by vestigial pinnae; lamina about 67 
cm. long, abruptly reduced at the base, somewhat reduced at 
the apex; pinnae about 30-jugate, 16-30 cm. long, 3-4 mm. wide, 
heavy, the upper ones decurrent on the lower side, the lower with 
occasional basal protuberances;{ sporangia dark brown; indu- 
sium quite regularly lacerate, and occasionally so to the base.

basal pinnae in the sterile lamina.]

This species has long been confused with the species Boryana 
(Onoclea Boryana Sw.), originally described from Africa. 1ne 
original illustrationt shows a very different plant with fewer, short, 
elliptical, distant pinnae; the original description mentions a 
arboreous stem, four feet high, and ovate-oblong pinnae which 
are obtuse and 5-10 cm. long. Even the descriptions of this 
species by American authors have been influenced by those of 
the African Boryana; e. g., Jenman describes the Jamaican plant 
as having an arboreous trunk. It has therefore been necessary 
to describe the Jamaican species, giving it a new name, S- 
Underwoodiana, for Professor L. M. Underwood, who collected

* In the other species the costae are definitely raised on the lower side; 
the shining costae look as if smoothed o- ironed down.

A small plant, probably S. Underwoodiana, was brought to the N 2 
ical Garden conservatories by Professor F. S. Earle from Jamaica 19 si ee cm 
about nine years but never seemed vigorous. In rg1r it had a rhizome i

pinnae suggested S. Shaferi; the laminae were less reduced at the a 
Shaferi, and the pinnae could hardly be called auricled on the lower side.
