Mozamb. Dist. Portuguese East Africa: Zambesi Delta: Kongoni River, 
Kirk! Luabo River, Kirk! Lower Shire Valley, Meller! Rhodesia ; by the 
Shangani River, Rand, 191 (ex S. Moore) ; on the sundy bed of the Shasha River, 
Baines! Bechuanaland: Kalahari Desert, Farini ! 
Also in North and South Africa, the Mascarene Isles, Madeira, Canaries, Arabia 
and South Europe, perhaps introduced in some of the localities. 
19. A. rostrata, V. Z. Br. A bush about 3-5 ft. high; young 
parts of the stem and branches white-tomentose, at length becoming 
glabrous. Leaves ascending or somewhat spreading; petiole 2-4 
lin. long; blade 13-4 in. long, 2-45 lin. broad, linear or linear- 
lanceolate, acute or very acute at both ends, minutely puberulous on 
both sides, becoming nearly or quite glabrous, flat, or the margins 
very narrowly recurved. Umbels lateral at the nodes, pedunculate, 
5-8-flowered; peduncle }-1 in. long, more or less white-tomentose ; 
bracts very caducous, 2 lin. long, subulate or linear-lanceolate, acute, 
tomentose; pedicels 41-7 lin, long, tomentose. Sepals 1} lin. long, 
4-3 lin. broad, ovate or ovate-lanceolate, acute or acuminate, 
tomentose. Corolla 5-lobed almost to the base, greenish-white ; 
lobes 2? lin. long, 13-2 lin. broad, elliptic-ovate, minutely notched 
at the obtuse apex, ciliate along one margin, elsewhere glabrous. 
Coronal-lobes arising } lin. above the base of the staminal-column and 
reaching to the top of it, 14-13 lin. long, erect, complicate, laterally 
compressed, subrectangular in side view, apical margin slightly 
rounded; inflexed sides with a reflexed falcate tooth at their apex, 
nearly as long as the breadth of the lobe, and slightly rising above its 
apical margin; no tooth or crest within the lobe. Staminal-column 
2 lin. long; anther-appendages ovate, obtuse, thin, tips just inflexed 
over the margin of the flattish, crenately-pentagonal apex of the style. 
Pollen-carriers seated under the rim of the truncate apex of the style. 
Follicles obliquely ovoid-inflated at the base, produced into a stout 
subulate beak 1-11 in. long, white-tomentose when quite young, soon 
becoming nearly glabrous, quite smooth, without any bristles. 
_ Lower Guinea. Angola: Amboella ; between the River Kubango and the 
River Kuito, Baum, 500! 
Mozamb. Dist. Ngamiland; Lake Ngami, only growing on the dry shore of 
the lake or river, Lugard, 22! Okavango Valley, 3000 tt., Lugard, 231! 
This species has been distributed from Berlin as 4. fruticosa, Linn., from 
which the smooth long-beaked fruit at once distinguishes it. It is remarkable for the 
manner in which the rim of the flat or slightly concave apex of the style projects 
ver and partly conceals the pollen-carriers. 
20. A, flavida, V. 4. Br. in Kew Bulletin, 1899, 259. A woody 
much-branched shrub, 3—-44ft. high; branches divergent, white-tomen- 
se. Leaves opposite, spreading, 14-3 in. long, 1-3 lin. broad, sub- 
Sessile or with petioles 4-1 lin. long, linear, acute, tapering at the 
base, revolute along the margins, glabrous, with the midrib adpressed 
pubescent beneath. Umbels several, lateral at the nodes along the 
upper part of the branches, pedunculate, 4-5-flowered ; peduncles and
