The Ferns of South Africa. 
Lady Barkly also grouped all under A. conforme. Schlech- 
tendal’s A. angustatum is evidently this species though with a 
longer stipe. 
A. viscosum grows more or less throughout S. Africa, but I 
have only seen A. conforme from Western Province, and A. 
latifolium from Natal. Buchanan and Wood used the name A. 
conforme for A. viscosum. 
Acrostichum conforme. Swartz; Hk. Sp. V. 198; Hk. and Bkr. Syn. 
Fil. 401 ; (not Schlechtendal ; Kunze ; Buchanan ; nor Wood.) 
Acrostichum angustatum. Schl. Adum. 14. tab. 5 ; Kze. Linnsea. 10.494. 
Olfersia angustata. Pappe and Rawson, 44. 
Elaphoglossum. Moore. 
Baker and Kuhn place Vittaria acrostichoides, Hk. and Gr. 
186 (Kze. Linn. 10.528 ; P. and R. 53), as an abnormal form of 
this with the sori in two sub-marginal lines. 
Widely distributed in the tropics.

Mountain (Bolus) ; Hottentot’s Holland; Caledon (P. & R.) ; George

bosch (Zeyher).

Plate CXXXI. Natural size. 
Rhizome stout, woody, creeping, thickly clothed with wavy, 
pointed, dark scales. Barren fronds very various, lanceolate or 
ovate lanceolate, widest below the middle, rounded or tapering to 
the stipe, and narrowed above to a blunt point ; half to two feet 
long, two to four inches broad, with a naked light coloured stipe 
two to eight inches long. Frond quite glabrous, thickly coriaceous, 
with hidden veins, and entire cartilaginous undulated edges. Mid- 
rib prominent. Fertile frond rather smaller and narrower, the 
under surface covered with sori except the mid-rib and edges. 
Very near A. conforme, Sw., and some Table Mountain specimens 
of that species approach this very closely. Kuhn makes them 
synonymous.
