NEW HYMENOPHYLLUMS AND TRICHOMANES. 



The following Hymenophyllums and TricJiomanes have been recently 

 introduced by Mr. Backbouse, but although I have been unable as yet to 

 procure fronds of them, it has been deemed advisable before finishing the 

 volume, to briefly enumerate each. 



HYMENOPHYLLUM ABEUPTUM, Eoolcer —A dwarf Fern, with 

 broad, blunt, pinnatifid fronds, on wiry stalks. Native of Jamaica, densely 

 carpeting mossy trunks and rooks. Fronds an inch and a half to two 

 inches in length. Figured by Sir W. Hooker, plate 31 — B, vol. i, "Species 

 Filicum." 



HYMENOPHYLLUM ^RUGINOSUM, Carmichael, BooTcer. (Hy. 

 menophyllum franklinianum, Colenso, Trichomanes seruginosum, Thours.) — 

 A well-marked species, with ovate, dense, tripinnatifid fronds, covered with 

 a whitish pubescence. Native of New Zealand. Pendent from rocks and 

 trunks of trees. Fronds four to eight inches in length. There is a variety 

 with more acuminate fronds, and with more distinct pinnse and divisions, 

 which is named var. franlclinianum. Figured by Sir W. J. Hooker, plate 

 34 — A, vol. i, "Species Filicum.''
