204 THE FERNS OF SOUTH AFRICA 
(Pellaea andromedaefolia Fee. 
A llosorus andromedaefolia. P. and R. 31; Kunze, Linnaea , 10, 503. 
This is included by Pappe and Rawson, Kunze, and Lady 
Barkly from Drege’s specimens collected at Kendo, and is 
still retained in Syn. Fil. (150), but was not seen by Pappe 
and Rawson nor Lady Barkly, while Kuhn excludes it from 
Africa as a mistake. 
An unnamed specimen in Herb. Gub. without locality does 
not differ in any essential point from the description in Syn. 
Fil. of P. andromedaefolia , but is certainly a dry grown and 
very much involuted form of P. quadripinnata. Baker, how- 
ever, writes me that “ P. andromedaefolia is in Hb. Drege 
from ‘ dry localities at Kendo ’ — Herb. Kew, Herb. Rawson.” 
Christensen credits it to America only.) 
102. Pellaea Boivini Hk. 
Plate 93. Nat. size. 
Frond deltoid, two-pinnate or three-pinnate, four to nine 
inches long, three to six inches broad, on a black stipe three 
to six inches long. Pinnae stalked, ascending, deltoid, in 
opposite pairs ; the lowest the largest, three inches long, 
two inches broad at the base, and having about four pairs 
of opposite pinnules, of which the upper are simple, and the 
lower three- foliate ; other pinnae smaller upward, and mostly 
with simple pinnules. Pinnules coriaceous, three-quarter inch 
long, two to three lines broad, broadest below the middle, 
and tapering upward to the blunt point, and downward to 
the cordate base ; all shortly stalked, and with a black mid- 
rib prominent to the point on the under side. Rachis and 
secondary rachises black, and densely set with short brown 
tomentum. Sori intramarginal, with a very broad indusium. 
This species is near the larger form of P. viridis , var. glauca , 
but has blacker, more rigid, and tomentose rachis, and broader 
indusium. 
F'ound near Magalisberg, Transvaal, by Zeyher and Burke, 
and it also occurs in Madagascar, Mauritius, and India.
