11. C. capense (Don ex Steudel, Nomencl. ed. 2, i. 382). This 
may be a synonym of CO. glabrum, E. Meyer. 
XIV. AVICENNIA, Linn. 
Calyx short, 5-partite, unchanged in the fruit, with broadly ovate 
imbricate lobes. Corolla with a short wide cylindric straight tube ; 
limb spreading, 4-lobed ; lobes subequal or the posterior a little 
broader. Stamens 4, inserted in the throat of the corolla-tube ; 
filaments very short ; anthers scarcely exserted, with parallel cells. 
Ovary with a central 4-winged conical column, imperfectly 4-celled ; 
ovules 4 (1 in each cell), pendulous from the apex of the axile 
placental column. Fruit dry, compressed, dehiscing by 2 thickened 
valves, l-seeded. Embryo naked on account of the arrested develop- 
ment of the integuments of the ovule; cotyledons large, longi- 
tudinally folded ; radicle inferior, villous ; plumule commencing to 
grow before the fruit falis (cf. Rhizophora). 
Glabrous or canescent shrubs; leaves opposite, entire, coriaceous ; cymes 
contracted, capituliform, pedunculate, usually paired in the axils of the upper 
leaves or arranged in a short thyrsus or trichotomous corymb at the apex of the 
branch ; flowers small, sessile, each with 2 bracteoles in the axil of a bract ; bracts 
and bracteoles shorter than the calyx. 
Three species, on the Tropical shores of both hemispheres. 
1, A. officinalis (Linn. Sp. Pl. ed. i. 110) ; a shrub or small tree ; 
young branches terete, furrowed, clothed with a dense minute white 
or yellowish-white indumentum, later glabrescent ; leaves oblong, 
oblong-lanceolate or elliptic, acuminate, acute or obtuse, narrowed at 
the base into the short petiole, entire, coriaceous, thick, green, 
glabrous and prominently reticulately veined above, densely clothed 
by a minute white or yellowish-white indumentum beneath, 2-3 in, 
long, 9-13 lin. broad ; spikes dense, globose, terminal and axillary, 
supported on short acutely 4-angled peduncles ; bracts and bracteoles 
broadly ovate, densely silvery tomentose along the margin and on the 
back or glabrescent, glabrous above, about 1} lin. long ; calyx-tube 
very short ; lobes broadly oblong or elliptic, rounded at the apex, 
glabrous within, pubescent on the back and margins, about 2 lin. 
long ; corolla-tube 4-1 lin. long; lobes 4, oblong, yellow, glabrous
