132 ASPLENIUM, § EUASPLENIUM. 



— As the Aspl. Icetum (our n. 92), the close ally of this species, is peculiar, as far 

 as yet known) to the New World, so is this to the Old World, and it is not to 

 be wondered at that both Waliich and Bhinie (under the name of abscismm) 

 should refer this Fern to the A. Icetum, Schk. It is, however, really distinct, yet 

 very variable ; so that the characteristics are not easily defined in words. The 

 caudex is however here unusually long, branched, and creei)iiig, and the pinnse 

 have not their ujjper base dilated into a distinct auricle. The figure in ' Icones 

 Filicum' well represents the normal state of the plant. 



89. A. (Euasplenium) " rhomboidale, Desv. ; pinnae sub- 

 opposite dimidiate crenate in the superior margin, inferior 

 margin entire, sori 2-3 oblique (ahnost transverse) with re- 

 gard to the costa and close to the inferior margin." Desv.

Hab. Martinique, Plumier. — Desvaux seems merely to have given a name to a 

 bad figure of some otherwise unknown Fern of Plumier, to which Lamarck had 

 applied a better name, but his description was mainly intended for a Bourbon 

 plant, no doubt ^s/;/. resecfum, Sm. The accurate Swartz, indeed, doubtfully 

 quotes Plumier's figure under that species, but its want of creeping caud'ex 

 forbids the union of the two. 



90. A. (Euasplenium) lii(/Hbre,'Liebm.; "stipes 4-6 inches 

 long, frond herbaceous glabrous blackish-green paler and 

 glaucous-green beneath 9-12 inches long 3 inches wide lan- 

 ceolate attenuate at the apex pinnated, pinnoR alternate hori- 

 zontal patulous 16-22 on each side shortly petiolate trapezio- 

 lanceolate subfalcate obtuse 1-H inch long 4-5 lines wide 

 obliquely cuneate at the base above truncated inferior base 

 resected the margin slightly incrassated revolute superior and 

 anterior margin obtusely serrated, serratures emarginate the 

 pinna; gradually diminishing in size upwards and sessile at 

 length confluent, sori numerous biserial approximate to the 

 slightlyprominulouscosta; stipes and rachis castaneous shining 

 glabrous slightly flexuose upwards channelled in front, con- 

 vex at the back, rhizome horizontal fleshy naked (not scaly) 

 emitting numerous strong intricate fusco-villous radicles."

Hab. Mirador, Mexico, Liebmann. — " Differt ab A. exciso" (the author surely 

 means abscissa, his immediately previous species, for Aspl. excisum is a name of 

 Presl for the Indian A. resecfum, which has a creeping caudex), " cui proxima 

 rhizomate repente iiudo, rachi pinnarum non niarginata, serraturis irregularibus 

 emarginatis." — The plant is quite unknown to me, as it seems to be to Mettenius 

 and Moore.
