43. A. (Euaspleniuni) Prionitis, Kze. ; caudex " creeping 

 paleaceous witli long membranaceous fuscous shining ovate 

 much acuminated scales," stipes G inches or more loTig, frond 

 broad-ovate a foot or more long impari-i)innate subcoriaceous, 

 pinnce 4-5 inches long petiolate oblong- or ovato-lanceolate 

 acuminate (lowest pair abbreviated) superior base truncate 

 inferior inciso-cuneate deeply sharply and irregularly ser- 

 rated, terminal one petiolate rather longer than the rest, 

 veins distant, sori distant oblique linear-oblong neither ex- 

 tending to the costa nor to the margin, involucre pale firm.

Ilab. South Africa, Natal, Dreye, Pajipe and Rawson. — Allied, as Kunze ob- 

 serves, to A. gemmiferum, but aiiparently distinct. The lowest pair of pinnae is 

 dwarfed, shorter indeed but ecjually wide with those above, and their form is sub- 

 rhoniboidal deeply excised at the inferior base. I have only two specimens I can 

 certainly refer to this species, one the lower part of a large frond, named by 

 Kunze ; the other more perfect one is from Dr. Pappe. The deep sharp serratures 

 are among its more distinguishing features ; but it requires a greater number of 

 specimens to enable nie to feel satisfied that it is a genuine species. Some indi- 

 viduals of A. anisophyllum have great affinity with it. 



44. A. (Euaspleniuni) vulcanicum, Bl. ; caudex "erect 

 H inch in diameter thickly clothed with membranaceous 

 brown ovate acuminated scales 6-8 lines long," petiole pale 

 6-8 inches long compressed, fronds 1-2 feet long pale-green 

 coriaceo-membranaceous impari-pinnate, pinnae petiolate 

 often proliferous in the axils 4-6 inches long lanceolate 

 finely acuminate entirely or obscurely serrated more dis- 

 tinctly towards the apex the base, nearly equally cuneate, 

 veins simple and forked very patent, sori numerous linear 

 near the costa but remote from the margin, involucre pale 

 firm-membranaceous. — BL En. Fil. Jav. p. 176. Metten.

Hab. Java, Blume (summit of the volcanic mountain Cede), Thos. Lobb, Zol- 

 linger, n. 2106.— A graceful Fern, of a delicate whitish-green colour. Most of my 

 specimens have the pinnae entire or nearly so. Mettenius's figure, from Zollinger's 

 plant, represents much stronger serratures than I have seen, and he describes the 

 veins as undivided, whereas be observes, " In descriptione Blumeana satis congrua 

 nervi dicuntur furcati." Also he speaks of the sori on the pinnic as " fere ad basin 

 dentium continuati ;" and of the pinnae being proliferous below the apex. In ail 

 my specimens, including one from Dr. Blume, the veins are copiously forked, the 

 sori do not approach the margin, and the proliferous gemma is always axillary. 

 Probably Mettenius's plant is something difierent.
