that his new species was founded on a specimen from Browne, not on the plates 
quoted. Subsequently Aspl. radicans L. (— A. rhizophyllum L.) is not the same as 
P. reptans Sw., and the right name of our species must be D. reptans (Gmel.). 
D. reptans is a common species in Jamaica and Cuba and occurs also but 
more rarely in some other islands, Florida and Central America. The smallest 
form occurs in the eastern islands, the largest in Cuba and Florida. I shall here 
mention some of the more characteristic forms. 
1. var. tenera (Fée). 
Syn. Goniopleris tenera Fée, 11 mém. 60 tab. 15 fig. 3. 1866. 
A small, thin-leaved form; leaves apparently never radicant. Stipe very slen- 
der, shorter than the lamina, this 6—12 em long, 5 em broad at the base; pinnz 
short-stalked, close, the lower ones reduced or not, about 2'/2 cm long by 1 em 
broad, obtuse at the point, rather deeply lobed, broadest at the truncate base. 
Veins about 3 to each side. — Differs from the next variety by its not radicant leaves 
and uniform fronds, from JD. asplenioides by its thin texture, not prominent veins 
and especially by the leaf tissue of both surfaces being rather densely but minutely 
pubescent by stellate hairs. 
JENMAN's var. fenera is probably not the same; | have seen no Jamaican 
specimens, which exactly corresponds with FÉr's type, although single leaves from 
rhizomes, which also bear radicant or differently shaped leaves, are very slightly 
different.

2. var. eu-reptans Jenman, loc. cit. 
Hereto a good many forms which | have tried in vain to distinguish from 
each other. Not only are two identical specimens not to be found but the leaves 
from the same rhizome also are often very different. Very often the sterile and 
fertile leaves are different, the former being very short-stalked, prostrate, rooting 
or nol, the latter much higher on long stalks and often of a much more rigid 
texture, radicant or not, the pinne generally distant; in other specimens also the 
short, prostrate leaves are fertile. The pinnz are very differently shaped, even in 
leaves of the same rhizome; in the short-stalked leaves they resemble those of var. 
lenera, i. e. short-stalked, obtuse at the apex, rather deeply lobed, 2—4 cm long, 
?|i—]1 cm broad, but not so closely placed. The long-stalked, most often fertile 
and often radicant leaves are more varying, the pinne being sessile or stalked, 
entire or crenate or lobed, often hastate at base, acute or rounded at the apex, etc. 
A peculiar form is that described as Pol. repandum Sw.; here the short-stalked, 
prostrate, sterile leaves are radicant, while the fertile leaves are very long-stalked 
(stipe up to 20 cm high), not radicant, pinne very distant, scarcely ‘/2 cm broad, 
2 cm long, a!most coriaceous, the margins revolute, crenate or almost entire; veins
