of Dr. Grcville. At a much later period the normal state of this plant, as I 

 consider it to he, was detected and confounded, hy Spreiigcl first and afterwards 

 hy Raddi, with the A. salicifolium of Linnaeus, from whicii it differs in several 

 respects. Among its many peculiarities are the strong creeping succulent root, 

 the dark-green and suhcarnose, suhpellucid fronds, the thickened margin to the 

 pinnaj, and the veins almost extending to the thickened edge. It is generally 

 noted to inhahit wet places in the vicinity of waterfalls, and the var. obtusifolium 

 looks, hy its smaller size and jagged and variously cut margins to the pinna^, as 

 if it might have suffered from too much water or from the falling force of that 

 element. Pluniier, indeed, calls it " Lonchitis arjua/ica." It is the more perfect 

 forms of this species which Mr. Moore has marked in my herbarium as Jsyl. 

 .salicifolium, and it may possihly be an aquatic form of it. If I am correct in 

 consi<lering A. riparium the more perfect state of A, obtusifolium, the latter ap- 

 pellation is very inapplicable to it. 



75. A. (Euasplenium) fuViyinosum, Hook. ; stipes short 

 erect or declined rather thick, stipites tufted very short 1-1 ^ 

 inch long and as well as the rachis clothed with spreading 

 sul)ul;ite very black crinite scales, fronds a span to a foot 

 long l)road-lanceolatc rather rigid-menihranaceous opaque 

 dark blackish-green when dry pinnated, the apex is ])inna- 

 tifid, pinn£e numerous approximate lanceolate subFalcate 

 acute rather than acuminate quite sessile and rather broad 

 at the base the margin crenulato-serrate, veins simple or 

 once or twice forked oblique, sori linear small occupying the 

 apex of the pinnae, involucres black, costa partially sctoso- 

 paleaceous at the back. — Hook. 2nd Cent, of Ferns, t. 3, ined. 



Hab. Kina Balu, Borneo, Hugh Loiu, Jun. — A very peculiar-looking species, 

 of a singularly gloomy i)lack colour when dry, crinite, with black, rather rigid, 

 spreading scales. It may rank near to A. riparium, but rather from colour than 

 general form : its exact affinities are rather doubtful. 



76. A. (Euasplenium) bicrenatum, Liebm. ; "frond sub- 

 coriaceous glabrous glaucous-green paler beneath 15 inches 

 long 6 inches wide (with the stipes 4-5 inches) lanceolate 

 pinnate, pinnae twelve to fifteen on each side gradually smaller 

 upwards alternate horizontal ])etiolate (petioles 2 lines long 

 compressed) 3 inches long 6-8 lines wide obliquely lanceolate 

 long-acuminate acute sui)erior base cordato-auriculate, auricle 

 rounded or angulato-rotundato-crenate, inferior base trun- 

 cated entire, the margin on both sides inciso-bi- rarius tri- 

 crenate with the crenatures obtuse, costa slightly prominent 

 in front sunk beneath, veins on both sides innnersed running 

 out at an acute angle and bifurcate, sori near the costa 3 lines 

 long, stipes and rachis glabrous brown channelled in front 

 acutangled at the back." Liebm. Fil. Mex. p. 93. — Metten.
