As typical I consider the following specimens: 
Nicaragua: San Juan del Norte, CuanLEs L. SmitH nr. 2098 (exactly typical). 
Costa Rica: Puerto Limon, Hot de la Uvita, Pirrier nr. 12703 (C, W) — Suerre, Llanuras de Santa 
Clara, 300 m.; J. DoNNELL SwrrH nr. 6929 (W) — Rio Turrialba, DoNNELL SMITH nr. 5093 (W). 
Forme: 
Guatemala: HeypeE nr. 731 (W; segments acute). 
Panama: Chagres, FENDLER nr. 403 (= Hayes nr. 36 (W, texture thinner, lobes narrower, base of lower 
pinnez about as in D. tristis). 
var. minor. Pinne ca. 15cm long by 2 cm broad, dark-green. Veins about 
10 to each side, the lower 4 connivent to sinus. — Resembles very much D. tetra- 
gona var. 2, from which it differs by its erect rhizome, which is up to 10 cm high. 
Guatemala: Alta Verapaz, Vicinity of Secanquim, about 450m., Maxon and Hay nr. 3196, 3217 (W). 
£251. Dryopteris paucipinnata (Donn. Smith) Maxon, Contr. U. S. Nat. 
Herb. 13: 19. 1909. 
Syn. Nephrodium Fendleri var. paucipinnatum, Donnell Smith, Bot. Gaz. 12: 
134. 1887. 
Type from Guatemala: Alta Verapaz, Petet, leg. H. von TóncknErM, ed. Donn. 
SurrH nr. 667 and 767 (W, B). Other specimens from the same region were col- 
lected by DouNELL SwurrH nr. 1556 (W) and v. TónckHnErM nr. II. 1690 (W). 
Described in detail by Maxow (loc. cit) and by him rightly separated from 
D. Fendleri as a distinct species. It is not at all allied to D. Fendleri, which belongs 
to a different group, but intermediate between D. Schaffneri or D. tristis and D oblite- 
rata. It resembles D. Schaffneri in its submarginal sori and distinct, persistent in- 
dusia, D. tristis in the cuneate base of the pinnz and in venation, D. obliterata in 
the general habit. It differs from all these species by its practically quite glabrous 
leaf, rigid to coriaceous texture and warted under-surface, from the two first-named 
species by its less incised pinnz, which is pinnatifidly cut about '/s. From D. Fend- 
leri it differs inter alia by its remote, alternate pinnee with a cuneate base, venation 
and lack of aérophore and febrils beneath. Generally the lowermost 4—6 veins are 
connivent to sinus, but occasionally the lower pair are united. Sporangia glabrous. 
252. Dryopteris Fraseri (Mett.) O. Ktze. Rev. 2: 812. 1891; C. Chr. Ind. 266. 
Syn. Aspidium Fraseri Mett.; Kuhn, Linnaea 36: 109. 1869. 
Nephrodium Fraseri Bak. Syn. 495. 1874. 
Nephrodium brachyodon Sodiro, Cr. vase. quit. 268. 1893! 
Type from Ecuador, leg. Fraser 1859 (B!); identical specimens from the 
same country were collected by SrósBEL nr. 762 (B) and Sopino (C). 
A large species, very characteristic in habit but otherwise closely allied to the 
other large species of this group. Pinnz at distances of up to 10 cm., opposite,
