a Meniscium. It is really an intermediate link between Goniopteris and Meniscium 
and therefore I agree with METTENIUS in reducing Meniscium to a subgenus of Dry- 
opteris. The difference is found mainly in the position of sori; if the sori are born 
on the vein near the point, where two opposite veins unite, the two opposite sori 
become with age confluent and thus we have a meniscioid sorus. — D. meniscioides 
has 8—10 lateral pinne, about 20 cm long and 3'/2em broad. Their edges are car- 
tilaginous, a little thickened and sparsely ciliate. — Goniopteris rostrata Fée, referred 
hereto in my Index, belongs to D. glandulosa.

A larger plant than D. Poiteana with only 2—5 pairs of lateral sessile pinne, 
which are 20—30 cm long by 5—8 cm broad, from subentire to irregularly serrulate 
or lobed. Stipe 3—4 dcm long, raised from a creeping, nearly scaleless rhizome, 
glabrous. Pinne slightly strigose on the veins above, densely soft-hairy beneath. 
Costze and costules as a rule not stramineous. Veins in 10—12 pairs, all, the 2—3 
uppermost pairs excepted, anastomosing under broad angles, generally all meniscioid. 
Sori about medial on the vein, in some specimens distinctly inframedial, in others 
nearer the anastomosing point. Sporangia glabrous even as young but intermixed 
with long hairs from the receptacle. 
Apparently a very distinct species when only the typical form is considered, 
but it is not always easy to distinguish from the andine forms of D. Poiteana. The 
best characters is the venation and the glabrous sporangia. The species is confined 
to Central-America, from Southern Mexico to Costa Rica, a region where D. Poiteana 
does not occur (Mexico) or is rare. I have seen the following specimens besides 
numerous cultivated ones.
