Related rather to Schizoloma guerinianum Gaudich., than to S. divergens 

 (Wall.) Diels, which has comparatively long and narrow pinnae and pale foliage. 

 The pinna? are articulate to the rhachis, but rarely separate from it. About one 

 pinna in ten shows an anastomosis of veinlets. It is smaller than 8. pellaeiforme 

 (Christ) Christen. (Lindsaya pellaeiformis Christ, Fil. Saras. 287; Ann. Jard. Bot. 

 Buitenz. 15 (1898) 102. pi. ///. f. U/.), and has comparatively much deeper pinnae.

Athyrium hyalostegium Copel. sp. nov. 



Khizomate ad terram repente, plerumque intertexto, 1 mm. crasso, 

 paleis mirmtis ferrugineis sparsis vestito; stipitibus caespitosis, 4-8 cm. 

 altis, filiformibus, stramineis vel viridulis, pedes versus brunnescentibus, 

 sursum rhachibusque pilis albis 0.3 mm. longis sericeis; fronde 3-7 cm. 

 alta, 1.7-4 cm. lata, acuminata, bipinnata, pinnis ovatis obtusis infimis 

 pinnatis, supremis integris coadunatis; pinnulis vel segmentis anguste 

 oblongis, obtusis, plerumque integris, herbaceis, pilis albis 0.5 mm. longis 

 sparsis pubescentibus; venulis simplicibus; indusiis tenuibus, setaceis, 

 rarius asplcniiformibus, saepius curvis et utroque latere venulae fere 

 aequaliter adnatis, i. e., nephrodiiformibus; sporangiis glabris.

 eodem. 



A distinct species, but of rather uncertain generic affinity. Athyrium seems 

 to me the most natural place; but ferns I can not distinguish from Nephrodium 

 distans (Don) Diels sometimes have athyrioid indusia. 



Athyrium aristulatum Copel. sp. nov. 



Bhizomate erecto, paleis cinnamomeis lanceolatis acuminatis 3 mm. 

 longis basibusque stipitum dense obtecto; stipitibus caespitosis, ca. 20 cm. 

 altis, gracilibus, basibus nigrescenti-stramineis paleaccis, sursum rhachi- 

 busque glabris viridulis; fronde 20-25 cm. alta, 10-13 cm. lata, acumi- 

 nata, tripinnata; pinnis lanceolato-ovatis, brevi-stipitatis, plerumque 

 acutis; pinnulis' oblongis, obtusis, rhachibus anguste alatis; pinnulis ll 

 oblongis, obtusis vel truncatis, adnatis, serratis vel dentatis dentibus 

 acutis plerumque aristulatis retroflexis, membranaceis, glabris, supra 

 atro-viridibus, infra pallidioribus; soris costalibus, indusiis brevibus, latis, 

 rectis vel curvis, albidis.

 Athyrium aristulatum var. sphagnicoium Copel. var. nov. 



Forma nana, stipitibus filiformibus 6-12 cm. altis, frondibus 5-10 cm. 

 altis, bipinnatis. 



Ibidem in apricis cum Sphagno. Copeland 1871. 



A very distinct species, conspicuous in the field for the pubescent appearance 

 of the upper surface, caused entirely by the very sharp, elevated or reflexcd teeth.
