 Gardner, n. 107.3. — This species, which I believe to be a distinct one, has much 

 of the general aspect of Jsjil. erecfum, especially the proliferous specimens, but 

 is at once distinguished by the glossy ebeneous-hlack stipites and racbis, and a 

 different arrangement of the sori -. in fact, its nearest ally is Asj>l. monanthemnm, 

 L., and the chief distinction, besides the softer texture of the j)innfc in the pre- 

 sent species, is the number of the sori, which in A. monaulhemum, as its name 

 implies, are reduced to one (rarely two) on a pinna, and situated near the lower 

 margin. In Aspl. multiju(/n?n the sori are more frequently above than below the 

 costa, and more numerous. The species seems to be wholly confined to Eastern 

 India and Ceylon, and in those countries to be very frequent. An original speci- 

 men of Kunze's A. opacum is in my herl)arium, and equally authentic specimens 

 of Aspl. mnlHcaide,\\a\\., and they are evidently identical with the same author's 

 Aspl. multijugum. 



99. A. (Euasplenium) monanthemuni, L. ; caudex short 

 thick densely rooted, stipites densely tufted purple-ebeneous 

 as well as the rachis 2-4-6 inches long, fronds 6-12-18 

 inches long firm-membranaceous fuscous-green elongato- 

 linear-lanceolate acuminate pinnated, pinnse numerous ^-f 

 of an inch long horizontally patent approximate at length 

 deciduous sessile or very nearly so obliquely semi-oblong 

 straight or falcate obtuse obliquely cuneate at the base, 

 inferior pinnae shorter and rhomboid, superior base dilated 

 into a short auricle truncate parallel with the margin, in- 

 ferior base cut off in a straight line half or more the length 

 of the pinna, the rest of the margin crenato-serrate, costa in 

 the lower half very near the margin, veins simple or forked 

 in the auricle, sori very generally solitary and elongated or 

 sometimes 2 rarely 3 confined to the lower half of the 

 pinna close to the margin and parallel with it, upper half 

 rarely with 1-3 oblique sori, involucre often Mhite-mem- 

 branaceous. — Linn. Syst. Veyct. ed. Murray, p. 1785. Sio.
