BROADHURST: STRUTHIOPTERIS IN NorTH AMERICA 267 
complete specimen seen), 2-3 cm. thick; the scales very scanty, 
ovate-lanceolate, about I cm. long, tobacco brown. Sterile fronds 
80-100 cm. long; stipes numerous, close, 27-45 cm. long, usually 
somewhat angulate, marked throughout with vestigial pinnae, 
which vary from mere scars to wide but very short lobes, chestnut 
to reddish purple and black, light colored in the channel, scales 
usually lacking; lamina 60-80 cm. long, 20-32 cm. wide, elliptical, 
rather abruptly reduced at the base (type D, with vestigial pinnae), 
the lower pinnae more or less distant (1 cm.), gradually reduced 
at the apex, the terminal pinna 3-8 cm. long, rachis light colored 
on the upper side; pinnae 18—35-jugate, the upper curved or 
falcate, the lower less curved to straight and oblong, the apex 
attenuate, the base broadly dilated, especially in the lower pinnae, 
which are 10-16 cm. long, 1-2 cm. wide (the lowest ones 3-6 cm. 
long and 2.5-3.5 cm. wide at their bases) ; margins entire, unevenly 
or not at all revolute; leaf tissue membranous to herbaceous, 
punctate as in S. exaltata, without scales; veins distinct, never raised 
hor grooved, the apices glandular as in exaltata, vein spaces 6-8 
tolcm. Sporophyls 88 cm. long (in the only complete one seen) ; 
stipes 30-40 cm. long, lighter than the sterile, the vestigial pinnae 
less prominent; lamina 45-52 cm. long, abruptly reduced at the 
base, the apex gradually reduced; pinnae 24—30-jugate, 10-15 cm. 
long, 3-4 mm. wide, the apex with a sterile tip 1-5 mm. long, the 
base dilated; indusium entire, not becoming lacerate; sporangia 
greenish yellow in fresh specimens. [PLATE 21. 
Type in the U.S. National Herbarium, no. 429499 and 429500; 
and in the New York Botanical Garden, collected near a stream 
i a wet ravine, forest near Hardware Gap, Jamaica, altitude 
4,200 feet, William Harris 10099, February 19, 1908. 
The type collected in 1908 has made possible the separation 
from S. exaltata of several incomplete specimens in the herbaria 
“2 Geneva and New York. S. jamaicensis differs from S. exaltata 
in being thinner in texture, widest at the middle, and in having 
more numerous pinnae with acuminate tips; it differs also in 
having lower pinnae which are much more dilated at the base, and 
Mia if not separated, appear so because of the flaring sinuses; 
€ fertile pinnae are evidently not soriated on the dilations as in 
S. exaltata,
