Africa, Bourbon, and India ; growing always among stones or 
in the crevices of rocks ; widely scattered, but frequent over the 
whole colony and Natal ; found also in the Free State (Harper), 
Transvaal (Zeyher and Burke), Damaraland (Marloth), Matebele- 
land — very much ivy-leaved — (Fry). 
51. Pell/EA Burkeana. Baker. 
Plate XXXV. Fig. 1. Natural size. 
Crown tufted ; fronds three to nine inches long, two to four 
inches broad, deltoid, pinnate or 2-pinnate, coriaceous, glabrous. 
Upper pinnae linear-lanceolate from a cordate base, rounded at 
the point, one to one and a-half inches long, one and a half to 
three lines broad ; lower pinnae similar, or with a similar terminal 
pinnule and one to four pairs of smaller side pinnules. Veins an- 
astomosing freely, but rather obscure, except the central one which 
is like the rachis and stipe, black, shining, and naked. Involucre 
rather narrow, intramarginal. When barren the pinnules are 
rather wider than when fertile. It seems to vary considerably ; 
one specimen in Herb. Gub. has frond eighteen inches long, and 
resembling P. hastata, Link., but with the indistinctly reticulated 
venation.
