The Ferns of South Africa. 
inches long, one-half to three-quarter inch broad, with a fragile, 
green, naked stipe one to three inches long. Upper pinnae 
cuneate, with three to seven sharp teeth ; lower pinnae as long as 
broad, nearly square, sessile, connected with the rachis at the 
lower corner ; the lower and inner edges straight ; the upper and 
outer edges sharply toothed ; the lowest pair or pairs of pinnae 
more distant, rather reduced, flabellate, and connected at the 
middle. Veins flabellate. Sori one to three to each pinna, alter- 
nate. Besides the ordinary fronds which are not proliferous, this 
species produces leafless fronds, which bend over and produce 
young plants at the apex. It grows among moss on stones and 
trees in deep shape, and often a whole mass of it is connected by 
these runners. 
No. 63 Herb. Barkl. seems to be this species, but the proli- 
ferous fronds are awanting. 
Kuhn quotes as a synonym Aspl. dentatum, Krauss (fil. Natal, 
194; Flora, 1846, 131 ; Pappe and Rawson, 19), and Buchanan 
and Lady Barkly follow, but the description given by Pappe and 
Rawson applies to A. Sandersoni, but not to this species ; while 
Krauss’ description I have not seen. L. dentatum, L., is given in 
Hk. and Bkr. “ Syn. Fil.” as a distinct American species.
