Stenochlaena Kunzeana (Presl) Underw. sp. nov.
Olfersia Kunzeana Presl, Tent. Pterid. 235. 1836 (nomen
nuduin).
Stems wide-climbing, more or less flattened, with occasional
brownish scales when young, becoming smooth except for the
abundant roots on the under surface; leaves 3 5-60 cm. or more
long, oblanceolate, tapering both ways from above the middle,
pinnate, borne on stalks 8-10 cm. long; pinnae 18-(or more)
jugate, those of the upper portion lanceolate, 6—12 cm. long, 10-
i"2 mm. wide, cuneate at the base, or long-tapering to a bordered
stalk, irregularly and usually coarsely dentate, acute or acuminate
at the apex, those of the lower portion of the leaf gradually re-
duced, the lowest becoming, ovate or ovate-triangular, 1—2 cm.
long; rachis winged especially when young, stramineous; midrib
prominent, lateral veins oblique, simple or rarely forked about 1
mm. apart; sporophyls pinnate, the pinnae 6 cm. or more long, 5
mm. wide, borne on a short (3 mm.) stalk, midvein conspicuous,
lateral veins distant, simple or usually forked at the base with the
branches widely diverging.
Specimens have been examined as follows:

Florida: Between Cutler and Longview Camp, 1903, Small
& Carter 836, 1137 ; Ross’ Hammock, Dade County, A. A.
Eaton 6’jy. All the Florida plants seen are sterile, but have the
unmistakable foliage of this species.
The genus Stenochlaena thus added to our flora is related to
Strutkiopteris in its dimorphous simply pinnate leaves, but lacks
an indusium ; the sporangia soon become confluent on the narrow
pinnae of the sporophyls and on this account the genus was
merged by Hooker with Acrostichum, with which, however, it has .
no natural alliance. The Florida plants scarcely represent the
norm of the species and apparently are straggling plants instead of
climbing ones, as in more tropical forests.
