202 POLYPODIUM, § EUPOLYPODIUM. 



yellow, oval, very close-placed, yet not confluent, sori. Possibly Swartz's plant 

 may be different from ours. 



93. P. (Eupolypodium) griseum, Liebm. ; "caudex hori- 

 zontal creeping thick as a swan's quill paleaceous with rigid 

 castaneous acute scales a line long, stipes and rachis stout, 

 frond herbaceous entirely canescently pilosulous 1-2^ feet 

 long 2-3 (or 4) inches wide, segments at the apex and base 

 diminishing in size horizontal parallel remote alternate or 

 subopposite linear-lanceolate 1-2 inches long 2-4 (and more) 

 lines wide rather obtuse obsoletely repand dilated at the 

 base decurrent above and below, costa a little prominent on 

 both sides, veins immersed branched, sori yellowish inter- 

 mediate between the margin and the costa." Liebm. Fil. 

 Mex. p. 46. 



Hab. Mexico, Dep. of Puebla, Liehmann, in Herb. Hook. Guatemala, Skinner. 

 — Accurately described by Liebmann. My specimens are very uniform. The 

 veinlets are twice or thrice forked, but only the lower superior branch bears a 

 small, yellowish, narrow-oval sorus at its apex. 



94. P. (Eupolypodium) Moritzianum^'Lik. ; " caudex creep- 

 ing, stipes ebeneous above scaberulous with short dense hairs, 

 fronds 1 foot long rigidly membranaceous opaque green some- 

 what hairy on both sides lanceolate deeply pinnatipartite, seg- 

 ments 1-H inch long linear gradually narrowing obtuse en- 

 tire broadly adnate at the base, lower ones with the superior 

 base produced, upper ones with the base equally dilated, 

 veins generally repetito-furcate, sori on each side the 

 costa of the laciniae in a single series near the margin."

Hab. Venezuela, Tovar, Moritz, n. 217 (from Mettenius), C. Wright, n. 214. 

 — Mettenius, in his Polypod., refers this Fern to P. Paridisecs (P. pectinatum, 

 nobis) ; but, attached to an original specimen, for which I am indebted to him, he 

 makes the remark, and I think correctly, "injusto inter synoiiyma P. Paradises 

 enumeratum." It is, however, one of many species of Ferns that are more readily 

 distinguished by the eye than in words. 



95. p. (Eupolypodium) siihserratum, Hook. ; caudex short 

 rather stout creeping, stipes 5 inches long erect stout dull black 

 muricato-hispid, rachis black minutely muricato-papillose be- 

 low, frond erect 8 inches long nearly 2 inches broad oblong 

 rather sharply acuminate truncate at the base firm-membra- 

 naceous dark-green above, paler beneath, regularly and deeply 

 pinnatifid to within a line of the rachis with rather close- 

 placed horizontal oblong very obtuse segments denticulate
