Dryopteris sp. 
Dunn 3810 is a quadripinnatifid plant, the raehises clothed with fine reddish- 
gray chaff', hitherto unknown to me. 
Dryopteris cuspidata (Bl.) Christ var. epigea Copel. var. nov. 
Ehizomate paleaceo epigeo, late repente, ramoso, fronde non prolifera, 
nec aliter typo Blumeano diversa. 
Matthew 1, Tai Mo Shan. “In marshy ground by stream. Rhizome creeping, 
above ground.” 
Polystichum aristatum (Forst.) Presl. 
Dunn 3878 is quadripinnate, and differs from the line-cut Philippine plants of 
this group in having almost glabrous stramineous raehises. 
Dictyocline Griffith ii Moore. 
Dunn 3759 , 3761, simple, deeply lobed fronds : Kemp, a sterile frond with five 
pairs of free pinnae. 
Dictyocline is certainly entitled to stand as a genus, characterized even better 
by its venation than by the hemionitidoid fructification. 
Lindsaya orbiculata (Lam.) J. Sm. 
Mr. Kemp’s collection includes both the round-leaved form, and the large and 
acute L. javanensis Bl. 
Athyrium (Diplazium) nudicaule Copel. sp. nov. 
Planta iota, teste Matthew, fere 2 m alta : rhizomate ca. 1 cm crasso, 
horizontale, nigro, fere nudo, squamis minimis nigris ad apicem vestito : 
stipite 5 mm crasso, ad pedem subaspero, atro; fronde tripinnatifida, 
acuminata, rhachi viride; pinnis alternantibus, patentibus, acuminatis, 
majoribus 50 cm longis; pinnulis subsessilibus, acuminatis, majoribus 
11 cm longis, 4 cm latis, rhachin versus truncatis, glabris, supra atro- 
viridibus, infra olivaceis, papyraceo-coriaceis, in lobos rotundatos 9 mm 
latos obscure serrulatos subeontingentes § ad costam incisis ; venis 
liberis; soris brevibus a costa vix ad mediam laminam protensis, inferio- 
ribus curvis; indusio angusto, mox desiccante. 
Kwangtung Prov., China, Matthew 33, 1907. 
A species of the D. maximum group, recognizable by the dark color, short and 
relatively broad pinnules set close together, short sori, and especially, having 
complete material, by the nakedness of the slender stipes and prostrate rhizome. 
With Milde, I treat Diplazium as a group or at most a subgenus of Athyrium. 
Athyrium (Diplazium) Matthewi Copel n. sp.

acutis, peclicellatis, infimis paullo brevioribus, supremis more A. maximi

latis, abrupte semitruncatis, adnatis, integris vel suberenatis; soris regula- 
ribus, parallelis, costam, nec marginem, attingentibus, diplazioideis ;
