ASPLENIUM, § EUASI'LENIUAI. 147 



affinity is with Aspl. flabellifolimn of New Holland, and with A. Kraussii of Natal : 

 from hoth of which it is very distinct : as it is also from the A. viride, in the 

 form of the pinnrc, which, too, are sessile, and in the singularly slender stipes and 

 rachis, as fine as the most delicate thread. 



109. A, (Euasplenium) Kraussii, Moore; small delicate, 

 stipes very slender stramineous scarcely an inch long, frond 

 lanceolate tapering below very tender-meml)ranaceous pale- 

 green pellucid pinnate, pinna) sessile apj)roximate 2 lines 

 long subobliquely cuneate scarcely suliflabcllate the obtuse 

 truncated or rounded apex strongly serrato-dentate the teeth 

 acute or submucronate, veins remote twice or more forked 

 subflabellate, sori 1 or 2 on each pinna oblong, involucre 

 nearly white thin membranaceous. (Tab. CLXXX. A.) —

Hah. Boschman's Rand, Natal, Krauss, n. 25. — The specimen here figured is 

 the only one I possess, and destitute of root and caudex : hut it is a well-marked 

 species, though confounded hy Krauss with A. dentatum, L. 



110. A. (Euasplenium) Sandersoni, Hook.; caudex a mi- 

 nute rhizome with copious fibrous radicles paleaceous at the 

 summit, stipites tufted 1-2 inches high pale-brownish-green 

 slightly paleaceous below with small lanceolate scales, fronds 

 soft-membranaceous but opaque-green 2-5 inches long lan- 

 ceolate acuminate spreading the rachis prolonged nearly leaf- 

 less and gemmiferous at the apex pinnate, pinnee distant dis- 

 tinctly petiolate 2-2i lines long obliquely cuneate or subfla- 

 bellate superior base truncate 3-4-lobed lobes very obtuse, 

 costa excentric parallel with and near to the inferior entire 

 straight margin, veins simple (or at the superior base forked) 

 distant short each terminating within a lobe, sori 2-3 on 

 each pinna oval, involucre pale membranaceous soon obli- 

 terated by the copious capsules, rachis compressed green.

Hah. Ravine in Field's Hill, Natal, /. Sanderson, Esq. — A very distinct and new 

 species, with singular ohliqucly cuneate, suhflahelliform pinna;, decidedly petioled, 

 the lohes nearly equal in size, very ohtuse. Its affinity is douhtless with A. Kraussii, 

 Moore (A. dentatum, Krauss, Fil. Natal, n. 25), but there the frond has terminal 

 pinnaj, the texture is delicate and subpellucid, the petiole is obsolete, the lower 

 pinna; are dwarfed, the teeth of all are singularly acute, almost mucronate, the 

 stipes and rachis are very slender and filiform. 



111. A. (Euasplenium) 7J7///?wrf'M;», Hook.; miimte, caudex 

 a very minute rhizome fibrous below with silky scales above, 

 stipites tufted brown a quarter of an inch long and as well as 

 the slender filiform rachis setose with lonsr hair-like dark-
