ASPLENIUM, § EUASPLENIUM. 91 



in some degree by its locality, so remote from the well-known stations of the 

 species. There seems no certain authority for its being a Pernvian Fern, still less 

 for its being a native of the Marianne Islands. It is very variable even in fronds 

 arising from the same caudex or rhizome, from rhomboid and imdivided to 

 deeply three-lobed. Sori, according to Mettenius, occasionally diplazioid. 



27. A. (Euasplenium) subhastatinn, Hook. ; caudex short 

 ascending paleaceous above, stipites tufted 4-G inches long, 

 fronds subcoriaceo-membranaceous about as long as the sti- 

 pites opaque pale-green rather broad-lanceolate acute or sub- 

 acuminate truncato-cuneatc at the base and subhastate having 

 an obtuse lobe on each side of the base, the margins quite 

 entire, veins distant, terminating within the margin and 

 clavate, sori linear rather short erecto-patent, involucres 

 narrow membranaceous. — Hook. Ic. PL t. 929 [or t. 29 of 

 Cent, of Ferns). 



llab. Caracas, (from Herb. Miguel.) — The fronds much resemble small speci- 

 mens of Scolopendrium vulgare, but the sori are truly those of Asplenium. 

 Mettenius suggests its being a young and abnormal form of some pinnated 

 species, for example, of A. salicifoliitm, L. It is far from impossible, but the 

 fronds are quite simple and yet bearing perfect sori : and I have seen no inter- 

 mediate forms. 



28. A. (Euasplenium) Hemionitis, L, ; caudex short ob- 

 lique subrepent paleaceous with subulate glossy black scales 

 above, stipites tufted 5 to 10 inches long black and paleaceous 

 below, fronds 4-6 inches long hastato-cordate 3-5-lobed 

 chartaceous bright-green, sinus very deep, lateral and supe- 

 rior lobes acuminate, middle lobe the longest, there is a 

 costa to each lobe, veins repeatedly dichotomous subradiate 

 approximate nearly all soriferous, sori extending from the 

 costa to the margin narrow-linear. — Linn. Sp. PL p. 1537.

Hab. Woody regions of North-western Africa, as far south as St. Nicholas of the 

 Cape de Verds, the Azores, Canaries, Madeira, and Spain and Portugal, or 

 South-western Europe. Found by all travellers, who are naturally attracted l)y 

 its beauty. — I must refer to the pages of the ' Botanical Magazine,' above quoted, 

 for information on the correct nomenclature of this species, elaborated i)y Mr. 

 Kippist. 



29. A. (Euasplenium) jnnnotifidum, Nutt. ; caudex short 

 creeping, stipites 4-6 inches long crespitose ebeneous at the 

 base, fronds rarely a span long submembranaceous flaccid
