ACROSTICIIIM, § KLAPHOGI.OSSI'M. 209 



thickish, stipites copious approximate and even crowded 4 

 inches to a span long suhrobust paleaceous throughout; 

 sterile fronds 3-4 inches long olilongo-lanceolate cosfate ob- 

 tuse coriaceo-membranaceous lobato-pinnatifid at the margin, 

 younger ones punctato-squamulose, veins obliquely patent, 

 costse beneath deciduously squamulose ; fertile ones small 

 subentire or sinuato-lobate. — Hook, and Grev. Ic. Fit. t. 145.

Hab. St. Helena, on rocks and walls : on the summit of Diana's Peak, Shider, 

 J. D. Hooker, Capt. llanghion. — A remarkable species, peculiar to the summit of 

 the little island of St. Helena. Fertile fronds very rare; for a long time I pos- 

 sessed but onesi)ecimen in that state at the time the figure was made for the Ic. 

 Fil. 1. c, but that arising from the same candex as the sterile fronds, Ilapi)ily 1 have 

 very recently received from Captain Haughton a series of beautiful siiecimens 

 fully confiiming the great accuracy of that plate, and consequently not justifying 

 the remark of M. Fee, that our figure " peche par I'exactitude, la fronde fertile 

 figuree u'appartenant pas vraisemblablement aux frondes steriles." Ample sjje- 

 cimens, too, from the same source, of the following species, A. hifnrcalum, also 

 confirm our views of the distinctness of the two species in opposition to those of 

 M. Fee. — See our observations on these two very interesting species in our 

 ' Second Century of Ferns.' 



32. A. (Elaphoglossum) hifurcatum, S\v. ; caudex hori- 

 zontal or ascending creeping imperfectly scaly at the apex 

 the rest quite glabrous and scaleless, stipites densely crowded 

 very slender stramineo-fuscous 3-6 inches long ; sterile 

 fronds 2-4 inches long oblongo-lanceolate with tiie rachis 

 winged, pinnae (or ratlier segments) linear distant simple but 

 generally once or twice forked costate or one-veined ; fertile 

 fronds smaller oblongo-linear obtuse, pinnae (or segments) 

 short cuneate or subquadrate, upper ones coadunate, the 

 apices bi-quadrifid or bi-trifurcate, veins bi-trifurcate. — Sw.
