Closely allied to var. pallescens and certainly not specifically distinct from D. 
oligophylla. Rachis and coste and veins beneath densely but very shortly downy 
by simple or sometimes forked hairs; scales rather frequent beneath. Sori just 
within the margin, furnished with a subglabrous indusium.

5. var. aequatorialis n. var. 
Rachis, coste and veins beneath and indusia densely but shortly hairy. 
Scales on the costz:: beneath rather numerous. Pinnz numerous, about 30 to a 
side, rather close, 25 cm long by 2 cm broad. 
A most distinct variety, very different from the Jamaican type but connected 
with it by the var. pallescens.

Syn. Nephrodium Tuerckheimii Donn. Smith, Bot. Gaz. 12: 133 tab. 11. 1887. 
Type from Guatemala, Dept. Alta Verapaz, near Coban, leg. H. v. TuERCK- 
HEIM, ed. J. Donn. SurrH. nr. 704 (W!, B); beautiful specimens were collected at 
the same locality in 1906—1907 by the same collector, nr. II. 1200 (W) and in 
the same region, Tamajü, ed. Donn. SurrH nr. 1568 (W). 
Perhaps the most distinct species of the whole group, intermediate between 
D. patens and D. oligophylla; it resembles the former in the sessile pinnae, which 
are not reduced towards the base, the basal segments being enlarged and the upper 
one often very large and lobed, and by the two basal veins only running to the 
sinus; it resembles the latter by its creeping, scaly, thick rhizome, by its strong 
stems and coriaceous texture; from both it differs by the densely scaly stipe, 
rachis and cost beneath. The scales are dull-brown, ovate or oblong-acuminate, 
glabrous and resemble mostly those of the rhizome of D. patens. In some speci- 
mens the stipe and rachis are entirely covered by such scales. The upper-surface is 
slightly pubescent, while the underside is densely soft-hairy on the ribs by long,
