THE FERNS OF SOUTH AFRICA 
more distinct. Placed as a variety of P. lineare by Baker 
(Syn. Fil ’), but maintained by Christensen as a species under 
the name P. excavatum Bory, from tropical Africa, Madagascar, 
India and Japan. 
Polypodium simplex Sw. Kuhn, Fil. Apr. 153. 
P. lineare Thbg, var. /3 simplex. Hk. and Bkr, Syn. Fil. 354; Sim, 
Ferns of S. Afr ., 1st ed., 198. 
P. excavatum Bory. C. Chr. Ind. 525. 
Polypodium loriforme Wall. Hk. Sp. 5, 57 (in part, Kuhn). 
Var. 7. SCHRADERI (Mett.). 
Plate 140. Nat. size. 
Rhizome slender, short, and tufted, with black linear 
scales. Frond thick and leathery in texture, three to five 
inches long, half inch broad, with the margin reflexed, and 
narrowed gradually to the base, but almost without stipe. 
Veins not distinctly visible without looking through, but the 
upper surface dotted all over with small holes like pin punc- 
tures. Sori more numerous than in the type. This form 
grows on rocks in sunshine, and in their extremes this and 
the type look very distinct, but gradually approach, evidently 
in accordance with the conditions of growth. Christensen 
maintains this as a species, from South Africa only.
