ASPLENIUM, § EUASPLENIUM. 89 



is certainly with my A. Griffithianum, but tliat is a very palc-coloiired plant, tlie 

 stipes not at all herbaceous, the fronds more lanceolate, the apex more acumi- 

 nate, and the margin coarsely crenato-serrate. 



21. A. (Euasplenium) coriaceum, Fee; "fronds simple 

 rigid coriaceous opaque lanceolate attenuated at both ex- 

 tremities, the margin entire convolute when dry, sori 

 narrow very long, indusium very narrow, proliferous ner- 

 vils prominent {in receptuculo nigrescente mutata), capsules 

 ovate, annulus 18-20 and more articulate, spores ovoid {luto- 

 episporatis)." — Fee, Gen. Fil. p. 193. ^ine Mem. Foug. p. 4G. 

 t. 15./. 1. 



Hab. Mexico, Galeotti {sine num.), Fee. — M. Fee says, "Cette fougure a le port 

 dfi Pleropsis anrjuHtifolia" but surely much 7nore does it resemble (judging from 

 the tigurc) our Aspl. ensiforme just described. Mettenius (to whom, as to me, it 

 is unknown) justly observes, " Patria, sed non charactere, ab Aspl. ensiformi 

 diversum videtur." Only a solitary sjiccimen, without caudex or rhizome, seems 

 to have been known to the author. 



22. A. (Euasplenium) ougustum, Sw. ; caudex short creep- 

 ing paleaceous with rigid dense subulate scales, fronds tufted 

 1-2 feet long 1-H inch wide, chartaceous pale-green narrow- 

 lanceolate very finely acuminated, below gradually tapering 

 into a very short stipes entire very obscurely serrated in the 

 acumen, sparsely paleaceous with minute scales, veins rather 

 distant obliquely patent, sori linear moderately broad ex- 

 tending nearly to the margin and occupying almost the 

 whole face of the frond. — A. angustum, Siv. Vetensk. Acad. 

 Handel, 1817, vi. jo. 6. t. 4. /. 1. Kze. Annul. Pterid. p. 21. 

 t. 14. Mett. Asplen. p. 89. A. loriforme. Hook. Ic. PI. t. 

 926 (or Century of Ferns, t. 2G). A. Surinamense, Fee, Gen. 

 Flip. 192 {Metten.). A. Weigelti, Kfs. {MS.), according to 

 Kze.; and Presl gives A. lanceola, Siv. (ubi?), as a synonym 

 of Weigelti. 



Hab. Guiana {Weigelt, Kegel, ITostmann), Schomburgk. Brazil, near Para, 

 Spruce. — A well-marked and graceful species, of which only small specimens are 

 figured by Presl in his ' Tentamen Pteridographia;.' Some of our fronds from 

 Para are 2 feet long, slender and loriform. 



23. A. (Euasplenium) ensiforme. Wall.; caudex short 

 thick scarcely repent bearing dark-brown subulate scales at 

 its summit and at the base of the stipes, fronds csespitose a 

 span to 1 and 1^ foot long ^ to | inch broad linear-lanceo- 

 late elongate firm coriaceo-carnose brownish-green entire 

 gradually acuminated and gradually and finely attenuated at 

 the base into a petiole 2 or more inches long, veins sunken
