DESCRIPTIONS OF THE SPECIES 
169 
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. 
Adventitious buds are produced irregularly on the upper 
surface of the frond. This is another of Sanderson’s finds 
which has not been seen since. I include it here simply to 
draw the attention of collectors to the matter. 
Buchanan remarks — “It seems to be a mistake. Mr San- 
derson knows nothing of it, and Kuhn positively denies it 
to be a South African plant {Fil. Afr. 203).” However, as 
explained elsewhere, Sanderson sent home up-country speci- 
mens without keeping notes or duplicates, and this may have 
been among them. The specimen in Herb. Gub. is distinctly 
A. jlaccidum, but it does not have Sanderson’s label, nor any 
explanation of how it came there, though attributed to 
Sanderson. 
A. odontites R. Br. ( Caenopteris 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.)

Crown erect, paleaceous, with numerous, lanceolate, dark 
scales. Frond two to three-pinnate, deep green, firmly herba- 
ceous, or sub-coriaceous, glabrous, ovate lanceolate, one-half 
to one and a half feet long, two to six inches broad, with a 
channelled, green, naked rachis, and a similar stipe three to 
six inches long. Pinnae ten to twenty alternate or sub- 
opposite pairs, deltoid or deltoid acuminate, often all fertile 
except the lower two pairs, which are then shorter, and not 
so much cut as the others, but frequently whole fronds are 
barren when they are different from the fertile. Barren 
pinnae blunt, cut to near the mid-rib into several cuneate,
