269. Dryopteris Andreana (Sod.) C. Chr. Ind. 252. 1905. 
Syn. Meniscium Andreanum Sodiro, Rec. 71. 1883; Cr. vase. quit. 392. 1893. 
Type from Ecuador, Andes quitenses, leg. Soprro (CI). 
Closely related to the preceding species, but its sori all meniscioid, the base 
of the sessile pinnze not subcordate but bluntly rounded with the lower side of the 
upper pinnae adnate to rachis, without aérophore (?), rachis, coste on both sides 
and secondary veins beneath sparsely pubescent by very short, simple hairs and 
the venation somewhat different. Secondary veins at distances of 4—6 mm with 
about 17—18 transverse, close and rather convex tertiary veins; the free, included 
veinlet short, rarely extending beyond the middle of the areole, sometimes nearly 
obsolete, its apex seen from above often broadly clavate as in D.ensiformis. Recep- 
tacle glabrous. — Pinne 20—40 cm long, 5—7 cm broad (18—24 by 3—5 cm according 
to SopiRo). — The species is not very near D. reticulata. 
270. Dryopteris pachysora Hieron. Hedwigia 46: 351 tab. 7 fig. 19. 1907. 
Type from Ecuador, Mt. Abitagua, STUBEL nr. 897 (BI). 
Differs from D. Andreana but agrees with the following two species by its long- 
stalked pinnz with a subequally cuneate base. Transverse veins 12— 14, the free 
veinlets long, extending beyond the middle of the areole, its apex scarcely clavate, 
or occasionally reaching the next cross-vein. The confluent sori very short and 
thick. Coste above very sparsely setose, the leaf otherwise glabrous. 
271. Dryopteris falcata (Liebm.) C. Chr. comb. nov. 
Syn. Meniscium falcatum Liebmann, Vid. Selsk. Skr. V. 1: 183. 1849. 
Phegopteris falcata Mett. Fil. Lechl. II. 23. 1859. 
Meniscium Jungersenii Fée, Gen. 223. 1850—52; Fourn. Mex. Pl. 1: 73 
(as Jurgensenii). 
Type from Mexico: Depart. Oajaca, Lacobe, LigzBMANN (H!). Also Costa 
Rica, Buenos Ayres, PrrrIER nr. 4839 (C). 
A very large species, widely different from typical D. reticulata. Rachis angular, 
glabrous, brownish-stramineous. Pinnz linear-elongate, 40 cm long, 3'/» em broad, 
dark-green, thinly membranous, apex long acuminate, margins undulato-crenulate, 
base subequally cuneate, long-stalked (petiole 2—2'/2 cm long), upper surface, the : 
very sparsely setose costa excepted, glabrous, costa beneath short-hairy. Secondary 
veins at distances of about 3mm with 12—13 transverse, a little convex veins; the 
included veinlets as a rule free but terminating in a subclavate apex above the 
middle of the areole, or not rarely prolongated and united with the next cross-vein. 
Sori small, nearly round, placed at the base of the free veinlet. Receptacle glabrous. 
Differs from D. pachysora by its much longer pinne of thinner texture, the 
coste hairy beneath and its small sori, from D. reticulata by its long and long- 
stalked pinnz with a cuneate, subequal base, pubescent cost€ and short sori.
