rhomboidal, a quarter to a third of an inch long and broad, 
cuneate, and entire in the lower half or more, irregularly rounded, 
and sparingly crenate at the apex. Sori one to three to a

“ This new Adiantum has been sent to the ‘ Gardener’s 
Chronicle’ by Mr. William Juby, for the last twenty-five years 
gardener to J. E. Wood, Esq., of Grahamstown. It was found in 
the mountains in the district of Bedford by Miss Paradise, and is 
named after that lady at Mr. Juby’s request. Of the numerous 
new forms nearly allied to A. cethiopicum, venustum, and cunea- 
tum, its nearest ally is the Himalayan A. Wattii. Bkr. (Journ. 
Linn. Soc., vol. 18, 381).”

Fig. 2. Variety, natural size, and magnified. 
Rhizome very long and slender, subterranean, slightly branch- 
ing, and set with grey or afterwards nearly black, lanceolate scales. 
Frond three-pinnate, ovate-deltoid, thinly herbaceous, light green, 
but not glaucous, six to nine inches long, three to five inches 
broad, with four to five pairs of alternate, rather distant, pinnae, 
which are compactly deltoid, two-pinnate, or occasionally three- 
pinnate. Pinnules small, shortly stalked, widely cuneate, one to 
three lines broad and long, broadest at the top ; entire or two 
lobed, each lobe bearing a crescent-shaped sorus sunk into a deep 
hollow. When not fertile the pinnules are larger, more rounded 
below, and finely serrated round the outer edge. Stipe three 
inches long, at first thickly set with chaffy scales, afterwards like 
the rachis and petioles, chestnut brown and shining, but very 
herbaceous in texture, and fragile. 
On the pinnae the rachis is almost hid from below by the over- 
lapping first pinnule on the upper side of each ultimate pinna. 
A variety differs from the more usual form in having rather 
larger pinnules, with the sorus quite reniform, and sunk so far into
