OF ORNAMENTAL EXOTIC PLANTS.

and which they call huku. The genus Diosma has been divided by modem botanists into several new genera, but as 
the plants are still generally Imown by their old names, and as, indeed, the new names do not appear to have been 
generally adopted even by botanists, I have retained all the plants in their old genus, and have only noticed the 
other names given to them under the head of synonymes. 
1.— DIOSMA UNIFLORA Lin. THE SINGLE-FLOWERED DIOSMA. 
Synonymes. — Adenandra uniflora Willd,; Hartogia uniflora Berg.; 
Eriostemon uniflora Smith.; Cistus humilis Bulk. 
Engraving. — Bot. Mag., t. 273. 
Specific Character. — Leaves scattered, oblong-lanceolate, some- 
what pointed, revolute, smooth, dotted beneath. Flowers solitary, 
terminal. Calyx ciliated. Petals obovate. ((?. Bon.') 
Description, &c. — This plant forms a small bushy shrub, the leaves of which are small and irregularly 
scattered over the branches quite up to the flowers, which are produced at the extremity of each shoot. The 
flowers are very large, being sometimes beyond the size of half-a-crown. The petals are white, with a streak of 
pink lamning down the middle of each ; they are also pink on the under side, and consequently look verj^ pretty in 
the bud, but when the flowers expand their beauty is somewhat injured by the petals being so far apart as to show 
the calyx between them. These flowers have no scent, but they are distinguished by a botanical peculiarity found 
in all the other species which Willdenow included in his genus Adenandra; and this is, that there are ten 
filaments, five of which are without anthers, but terminate in a thick concave or globose gland, the use of wliich is 
unlmown ; the other five bear anthers, which are large and egg-shaped. The species is a native of the Cape of 
Good Hope, whence it was introduced in 1775. 
2.— DIOSMA ACUMINATA Lodd. THE POINTED DIOSMA. 
Synonymes. — Adenandra acuminata Nweei ,• Agathosma acuminata Specific Character. — Leaves scattered, roundisb- ovate, rather 
Willd. ; Bucco acuminata Wendl. cordate. Peduncles terminal, umbellate. 
Engraving. — Lodd. Bot. Cab., t. 493. 
Description, &c. — The flowers of this species are large and white, with a pink stripe up each petal, as in the 
former species. This plant is, however, much more ornamental than D. unijiora, as the petals are not so far apart 
as in that species, and the calyx, instead of being a dingy gi’eeu, is pink. The glands of the sterile stamens look 
lilie little shells. The leaves are much more dense than in the last species, and they have a strong smell, which, 
however, is not so disagreeable as in some of the other kinds of Diosma, as it is somewhat aromatic. The species 
is a native of the Cape of Good Hope, and was introduced in 1805. 
3.— DIOSMA AM(ENA Lodd. 
Synonymes. — D. ovata Jlort. ; Adenandra amcena Sweet ; A. 
glandulosa lAch. 
Engravings. — Lodd. Bot. Cab., t. 161 ; Bot. Reg., t. 553. 
THE PLEASING DIOSMA. 
Specific Character. — Leaves oval, glabrous. Flowers sessile, 
disposed in terminal umbels. Petals imbricate, nearly orbicular, termi- 
nating in a small mucrone. 
Description, &c. — This is a very handsome species. The flowers are of a pale pink, with a dark pink streak 
up each petal, broader than in the other species ; the back of the petals is of a deep rose colour. The flowers, as 
in all the other species of the genus, last a long time without fading after they have expanded ; they are -without 
scent, but the leaves have the strong smell peculiar to the genus. The species is a native of the Cape of Good 
Hope, and it was introduced in the year 1798.
