25, A. Prederici, Wiern in Cat. Afr. Pl. Welw. i. 684 A shrub 
3-5 ft. high, branched ; branchlets white-tomentose. Leaves very nume- 
Tous ascending or somewhat spreading, 2-44 in. long, 1-24 lin. broad, 
linear, acute or subobtuse, narrowed at the base into a petiole, 1-2 
lin. long at the base, revolute along the margins, puberulous or 
nearly glabrous above, more or less white-pubescent beneath, Umbels 
numerous, lateral at the nodes, pedunculate, 5—6-flowered ; peduncles 
subequal, $—1 in. long, white-tomentose; bracts very deciduous, 2~2} 
lin. long, linear, acute; pedicels $—} in. long, tomentose. Sepals 
2 lin. long, lanceolate, acuminate, pubescent. Corolla lobed nearly to 
the base, minutely white-pubescent outside, glabrous within, probably 
reflexed when fully expanded ; lobes 34-4 lin. long, 2-2} lin. broad, 
elliptic-ovate, obtusely pointed. Coronal-lobes arising } lin. above the 
base of the staminal-column and reaching its top, 13-17 lin. long, 
1} lin. broad across the side, D-shaped viewed sideways, with the 
Inflexed sides rectangularly acute or subacute at their apices, but 
hever produced into distinct teeth. Follicles 1}-2 in. long, 1{ in. 
In diam., oblong-globose, inflated, very obtuse, beset with bristle-like 
Processes, pubescent all over, “sulphur-yellow spotted with purple, 
bristles ‘ violet-purple ” (Welwitsch). 
Lower Guinea. Angola: Pungo Andongo ; on the rocks of the Presidium 
and higher rocky parts of Pungo Andongo, Welwitsch, 4160! 4161! 4162! on the 
rocks of Pedra de Cabondo, 3500 ft., Welwitsch, 4163! Huilla; in the rocky 
thickets of Lopollo, Welwitsch, 4166! 
According to Welwitsch the flowers ure sulphur-yellow, greenish-yellow, or 
whitish-yellow. The coronal-lobes are described by Hiern as “ u-ually with an erect 
short lobule or tooth at the apex of each or one inner side.” I can find no structure 
of this kind in the specimens above quoted; where the straight inner margin and 
curved top margin of the lobe meet, they form a somewhat acute angle, nearly a 
tight-angle, but there isno tooth such as is found 1m the allied species. This species 
is not easy to discriminate from A. Burchellii, Schlechter, except when in fruit.

3-4 ft. high, branched ; branches white-tomentose, Leaves very numer- 
ous, erect or ascending, 14-4 in. long, }-2 lin. broad, linear, acute, 
narrowed at the base into a petiole 1-2} lin. long, revolute along the 
Margins, softly puberulous, becoming glabrous above, pubescence 
whiter beneath. Umbels numerous, lateral at the nodes, pedunculate,

Facts 2-5 lin. long, deciduous, linear, acute ; pedicels $—1 in. long, 
white-tomentose. Sepals 13-2 lin. long, 2 lin. broad, lanceolate, acute, 
reflexed, white-tomentose on the back. Corolla lobed nearly the 
e, minutely white-tomentose outside, reflexed, white; lobes 32 lin.
