CONSPECTUS TABULARUM. 27 
Derscr.—A shrub, 6 feet high, or more. Barkwhitish, tubercled. Leaves 
3-4 inches long, 14-24 inches wide, gradually or suddenly acuminate, 
finely and bluntly toothed, acute or obtuse; im our specimens rounded 
at base. Spines from 4 to 1$ inches long. Flowers white, 2 inches 
across, resembling white roses. Anthers tipped with a fleshy point, 
small, many times shorter than the filament. Fyrudt one-celled, with a 
solid shell, pulpy inside, and many seeded. 
The fruit, Mr. Gerrard informs me, is well known to the Natal and 
Zulu Kafirs, who wear it hung round the neck, and use it fora snuft- 
box, calling it thunga. This shrub is widely dispersed on the African 
continent. I have examined specimens from various quarters, but 
never found so few as 5 petals: is that number erroneous ?

Haz.—Damara Land, Miss Elliott. (Herb. T. C. D.) 
Descr.—A rigid, slender, much branched, small shrub. Branches gla- 
prous, with smooth, pale bark, opposite or scattered. Leaves 1_14 inches 
long, about 1 line wide, tapering a little to base and apex, subacute, 
strongly nerved. Pedicels slender, axillary, shorter than the leaf. Flowers 
conspicuous. Bractee 2, enclosing the calyx, connate below, boat-shaped, 
acuminate, papery-membranous and netted with slender, green veins. 
Calyx segments unequal, subulate, glandular. Corolla with a funnel- 
shaped tube and unequal, 5-lobed limb; the lobes very obtuse. Sta- 
mens 4; anthers mucronate at base. Style unequally bifid; ovules 2 in 
each cell. 
A very handsome plant, remarkable for its netted, white bracts. 
The only other known species of Petalidium is a native of India, and 
has broad, ovate leaves.
