DESCRIPTIONS OF THE SPECIES 277 
Transvaal. — Marovuni (Burtt-Davy, 288); Barberton (T. Williams, 
129); Pretoria (Mrs Potts). 
160. Polypodium Pappei Mett. 
Plate 14 1. Fig- 1. Nat. size. 
Rhizome slender, woody, running, branching, and rooting 
freely, clothed with lanceolate, pointed, deciduous, dark scales. 
Frond entire, thin, sub-coriaceous, glabrous, naked, lanceolate, 
one to two and a half feet long, one to three inches broad, 
tapering to a point, and tapering very slowly to a slightly 
margined naked stipe three to six inches long. Mid-rib con- 
spicuous, furrowed above, other veins rather obscure and 
irregular, but in large specimens having primary veins from 
the mid-rib to the margin at about every half inch distance, 
between which numerous areolae are formed, mostly including 
single or dichotomous free veinlets. In smaller fronds there 
are no primary veins, but numerous irregular areolae. The 
sori appear sometimes to have indusia present, through the 
central capsules blackening while the outer remain green. 
This optical delusion is revealed by a magnifying glass. The 
sori are superficial and sometimes in a row near the mid-rib, 
but more frequently scattered irregularly near the mid-rib, and 
not having any regular position on the veins. This latter 
condition in Hk. and Bkr Syn. Fil. is named P. normale 
Don, var. /3 P. longifrons Wall., and in our first edition we 
placed P. Pappei under P. normale Don, but Christensen 
restores P. Pappei Mett. for the South African plant and 
also maintains P. normale Don as from China, tropical Asia, 
New Guinea and Madagascar. 
Kuhn omits P. normale , but includes P. Pappei Mett., and 
I cannot distinguish a Natal specimen in Herb. Gub, named 
“ Phymatodes concinna , No. 6, N. sp.” (Pappe). 
Kaffraria. — (Rawson,yfofe Kuhn). 
Natal. — Maritzburg, Richmond, and York (McKen); Seven Mile Bush, 
Upper Umkomaas (Buchanan); Upper districts (Wood); Zwaartkop 
(T. R. Sim).
