5. var. tarapotensis (Hook.). 
Syn. Nephrodium larapotense Hook. spec. fil. 4: 107. 1862. 
A form with pinnz resembling in shape exactly those of D. Karstenii, with 
which MraTTENIUs identified it; it differs from that species by more veins (10—12 
to a side) and lack of articulated hairs on veins and coste beneath; from typical 
D. submarginalis it differs by its very obtuse segments.

6. var. Lagerheimii (Sod.). 
Syn. Nephrodium Lagerheimii Sodiro, Cr. vasc. quit. 252. 1905. 
Dryopteris Lagerheimii C. Chr. Ind. 273. 1905. 
Large; stipe and rachis very scaly; scales of the stipe below about 5 cm long, 
those of the coste beneath numerous and much broader than those of f. caripensis. 
Leaf 1 m long, pinnz 20 cm long by 3 cm broad; segments rather falcate, finely 
toothed at the outer part; veins 15—17-jugate; indusium often present. In general 
habit not unlike D. refulgens.

35. Dryopteris Karstenii (A. Br.) C. Chr. comb. nov. — Fig. 6. 
Syn. Aspidium Karstenii A. Braun, Ind. sem. hort. Berol. app. 1857: 3. 
Type-specimen in Bl, cultivated in Hort. Berol. and raised from spores of 
plants collected by KarsTEN in Venezuela. 
Closely related to D. submarginalis resembling it in the reddish scales, which 
form a tuft at the base of the stipes, but receding from it in the direction of 
D. falciculata. Compared with D. submarginalis the main characters of D. Karstenii 
are the following: Middle-sized; stipe 3'/2 dem long, like rachis clothed with hairs, 
hair-shaped scales and broader scales. Lamina 5—6 dcm long, 2—2'/» dem broad; 
largest pinnze 10—12 cm long, 2—2'/1 em broad; both sides throughout with short, 
scattered, reddish hairs, costae beneath furnished with hairs and scales and with 
all intermediates between these two kinds of trichomes (fig. 31°). Segments close, 
slightly oblique, entire, broadly obtuse and often emarginate, upper basal one often 
quite free and a little shortened. Veins 6—8-jugate, sori medial or a little supra- 
medial furnished with a persistent, ciliate indusium. 
— “Truncus erectus sensim supra lerram elatius demum fere pedalis una cum 
phyllopodiis laxius dispositis paleaceus" (A. BRAUN l.c.) while the caudex of D. cari- 
pensis is described thus: *truncus erectus supra terram elevatus demum semipedalis 
et altior una cum phyllopodiis satis confertis dense paleaceo-lanatus paleis valde 
elongatis (fere pollicaribus) linearibus in pilum excurrentibus” (A. BRAUN l.c. pag. 2). 
From D. falciculata and D. nigrovenia our species differs by the shape and 
structure of the scales.
