Closely allied to var. pallescens and certainly not specifically distinct from D. 



oligophijlla. Rachis and costæ 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, costæ and veins beneath and indusia densely but shortly hairy. 

 Scales on the costæ beneath rather numerous. Pinnæ 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.

197. Dryopteris Tuerckheimii (Donn. Smith) C. Chr. Ind. 299. 1905. 



Syn. Nephrodium Tuerckheimii Donn. Smith, Rot. Gaz. VI: 133 tab. 11. 1887. 



Tj'pe from Guatemala, Dept. Alta Verapaz, near Cohan, leg. H. v. Tuerck- 

 HEiM, ed. J. Donn. Smith nr. 704 (W!, B); beautiful specimens were collected at 

 the same locality in 1906—1907 by the same collector, nr. II. 1200 (Wj and in 

 the same region, Tamajii, ed. Donn. Smith 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 pinnæ, 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 costæ 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,
