pendrioides, but it agrees in all characters with the other species of $ Steiropteris, 
and we here come upon an excellent illustration of the unnatural manner of ar- 
ranging the species after the degree of cutting. Hookrm's plate cited above is a 
good figure of the species, and it is unnecessary to give here a new description. 
Aérophore is not present. It differs from all pinnatifid species of Dryopteris by 
the characters ascribed to § Steiropteris and from the other species of this group 
by its pinnatifid, not bipinnatifid lamina.

Type from Jamaica; leg. Swartz (S! H). 
A well-known species, which is the type species of § Steiropleris. The pinnz 
of the lower half of the lamina are reduced to mere lobes, which are reflexed and 
auricled at the base.

Type from Guadeloupe, leg. L’HERMINIER (B !). 
A distinct species resembling in size and general habit D. mollis and D. nor- 
malis, but really a near ally of D. deltoidea and D. Leprieurii, showing all the 
characters of $ Steiropleris: 
The wide-creeping rhizome is clothed at the apex with brown scales, which 
are lighter and thinner than those of D. deltoidea and D. lonchodes. The stipe is 
15—20 cm long, glabrous or finely pubescent. Lamina 2!/—4 cm long, 12—15 cm 
broad, slightly narrowed downwards, membranaceous, grey-green or brownish. 
Rachis, coste and both sides and costules beneath densely villous by short, uni-
