Lady Barkly, in a postscript to her revised list, writes : — “ We 
have received through Dr. Shaw, from Wakkerstroom, Transvaal, 
an Adiantum, which seems to be a connecting link between A. 
caudatum and A. lunulatum ; ” no doubt the same thing. 
(A. lunulatum, Burm., which occurs in Zambesia, resembles 
A. caudatum in habit, but has stalked pinnae two to three times as 
large, deep green, less cut, of thinner, more papyraceous texture, 
with continuous marginal sori, and the whole plant is glabrous.) 
(A. Oatesii., Bkr. (in Oates Matebeleland plate K), was 
gathered by the late Mr. Frank Oates in Matebeleland during his 
journey from Durban to Victoria Falls, Zambesia, but most likely 
within the tropics. The frond is divided in a sub-palmate manner 
into several pinnate pinnae four to six inches long, each bearing 
numerous lobed and one-sided pinnules like those of A. caudatum 
but larger. Whole plant is glabrous, and of thin texture.)

Plate XVI. var. major. Plate XVII. var. minor. 
Rhizome creeping on or near the surface of the ground, one to 
four inches long, one to four lines in diameter, fleshy, set with 
brown chaffy scales, and producing numerous fronds at short 
intervals. Fronds two to three pinnate, deltoid, four to eight 
inches long, three to six inches broad, on a stipe three to eight 
inches long, which is set below with chaffy scales at first, after- 
wards glabrous, black, and wary. Pinnae deltoid, pinnate, two- 
pinnate, or occasionally three-pinnate, with fine black hair-like 
rachis and petioles. Pinnules a-half to three-quarter-inch long, 
and about as broad, glabrous, cuneate, or tapering down to the 
petiole, deeply lobed, and when barren toothed at the edge ; of 
light green, delicate, and almost transparent texture. Sori longish
