after sunset, and through the night, they emit a powerful odour, like that of some kinds of fruit. The species is 
tuberous-rooted, and it is propagated either by seeds or by cuttings of the root. There are several other species 
nearly allied to this, all with tuberous roots, but they are now very seldom grown ; as they are not only inferior in 
beauty to the common kinds, but they are also much more difficult to cultivate. Some of them have been a 
long time in the country, as P. triste is said to have been introduced before 1632. 
7.— PELARGONIUM BICOLOR Ait THE TWO-COLOURED PELARGONIUM. 
Synonyme. — Geranium bicolor Jacq. 
Engravings. — Bot. Mag., t. 201 ; Sweet’s Geraniace®, t. 97. 
Specific Character. — Stem suffruticose. Leaves cordate, trifid. 
waved, hairy, obtuse, toothed, lateral segments three-lobed, middle 
ones five-lobed; stipules kidney-shaped, entire. Umbels crowded, 
many-flowered. Calyx reflexed. {G. Don.') 
Description, &c. — A very curious species, both in its leaves and flowers. It is still occasionally seen in old 
greenhouses, both in England and on the Continent, particularly the latter. The flowers are rather small, but 
they are usually of a very rich dark purplish crimson, edged with white ; and the leaves are green, edged with dark 
pui’plish red. The plant was introduced in 1778. P. pictmn hears considerable resemblance to this species, 
but the petals contain more white, and the leaves have not a dark margin. 
8.— PELARGONIUM CRASSICAULE L'Her. THE THICK-STEMMED PELARGONIUM. 
Synonyme. — P. primulinum Sweet. 
Engravings. — Bot. Mag., t. 477; and our Jig. 3, in PI. 15. 
Specific Character. — Stem fleshy, branched, smooth. Leaves 
kidney-shaped, rather acuminate, toothed, silky on both surfaces. 
Umbels many-flowered ; bracteas four times shorter than the pedicels. 
Petals obcordate. 
Description, &c. — The flowers of this species are very ornamental. The petals are white, with a blood-red 
spot in the middle of each, and the flowers smell like a Primrose. Both the leaves and stem are thick and fleshy, 
and the leaves are covered with a soft silky down on both sides. They are curiously plaited when young. This 
species was first discovered on the south-west coast of Africa, whence it was introduced in 1786. It requires a 
warm dry situation, and should he kept in a greenhouse all the year, as, from its root being tuberous, it is very apt 
to rot if the ground where it is placed is cold and damp. It is of very slow growth, and is propagated by 
cuttings, but with difficulty. It flowers in June and July.

9.— PELARGONIUM PELTATUM Ait. THE IVY-LEAVED PELARGONIUM. 
Synonyme. — Geranium peltatum lAn. Engravings. — Bot. Mag., t. 20 ; and ova Jig. 4, in PL 15. 
Specific Character. — Stem shrubby ; branches fleshy, angular; leaves peltate, five-lobed, quite entire, fleshy. Umbels few-flowered. {G. Don.) 
Description, &c. — The Common Ivy-leaved Pelargonium has pnik or pale crimson flowers, but there is a 
variety the flowers of which are white. The leaves are like those of the common Ivy in form, and have generally 
a dai’k ring in the centre. They are what is called peltate, that is, the stalk springs from the centre of the back 
of the leaf. The plant is a native of the Cape of Good Hope, whence it was introduced in 1701. It was for many 
years comparatively neglected, but it has lately become popular, and has been grown occasionally as a show-flower. 
It will bear planting out quite well in the open air, and is, in fact, hardier than several of the other kinds.
