144 CHARACTERS OF TRIBES AND GENERA. 
59.—PHOTINOPTERIS, J, Sm. (1841). 
Lomaria sp., Blume ; Acrostichum sp., Wall. ; Hook. Sp. Fil. 
Vernation uniserial, sarmentum scandent. Fronds distant, 
pinnate, 2 to 3 feet long, smooth, coriaceous, rigid, shining, 
the upper pinne contracted and fertile. Sterile pinne 
distant, alternate, elliptical, acuminate, 6 to 8 inches long, 
2 to 3 inches wide, petiole short, attached to the rachis by 
a scutiform lobe. Veins costeform, venules and veinlets 
compound anastomosing, forming quadrangular areoles. 
Fertile pinne linear, rachiform, 8 to 12 inches in length, 
their under side wholly sporangiferous. :

Oss.—My first knowledge of the singular Fern on 
which this genus is founded, was obtained from a specimen 
in the herbarium of Dr. Horsfield, which had been collected 
in Java, which led me to give it the specific name of 
Horsfieldii ; in 1822 it was found near Singapore by 
Wallich, and was named by him Acrostichum rigidum. It 
was, however, first described by Blume, under the name of 
Lomaria speciosa. It was also found by Cuming in the 
Philippine Islands, who described it to me as growing on 
trees, and being conspicuous by its shining fronds. In 
vernation it agrees with Gymnopteris, but its peculiar habit — ` 
and articulate pinne does not admit of its being associated 
with that genus ; in these characters it agrees with Drynaria | 
and Dryostachum, but its adherent vernation prevents its d 
. alliance with these genera, *
