The Ferns of South Africa. 
ceous, glaucous, glabrous, one and a half feet long, including stipe 
of six inches. Pinnae six pairs, linear acuminate, alternate, three 
to four inches long, one line broad at the sinuses and point, about 
four lines broad across the segments. Pinnules acute, one line 
broad and long, somewhat decurrent. Terminal pinna four inches 
long, with longer pinnules and sori than the others ; lower pinnae 
barren, not pinnatifid, but waved at the margin. Rachis and 
stipe slightly winged, wing disappearing below. Sori short, 
marginal on the upper margin of the pinnules, opening outward. 
The above description, as well as our figure, are from Sanderson’s 
specimen in Herb. Gub.; but the plant often grows stronger 
abroad, with fronds two to three feet long, and with numerous, 
flaccid, coriaceous pinnae, half-inch broad, and six inches long, cut 
into regular, linear or forked, pointed pinnules, three lines long, 
one line broad, and having one line between each : the lowest 
pinnule on the upper side longer, and again pinnatifid. Adven- 
titious buds are produced irregularly on the upper surface of the 
frond. This is another of Sanderson’s finds which has not been 
seen since. 
Buchanan remarks — “ It seems to be a mistake. Mr. Sander- 
son knows nothing of it, and Kuhn positively denies it to be a 
South African plant (Fil. Afr. 203).” However, as explained else- 
where, Sanderson sent home up-country specimens without 
keeping notes or duplicates, and this may have been among them. 
The specimen in Herb. Gub. is distinctly A. flaccidum, but it does 
not have Sanderson’s label, nor any explanation of how it came 
there, though attributed to Sanderson. 
A. odontites, R. Br. ( Ccenopteris , Thunb., P. and R. ; Darea , 
Willd., Schl. Adum. 32), recorded as found by Thunberg at the 
Cape, seems to be the same plant, but the locality is denied by 
Kuhn.
