Synonymes.— Geranium violaceum Jacg.; G. tricolor Andr.; Phy- Spreciric Cuaracter.—Stem erect. Leayes lanceolate, villously 
matanthus tricolor Sweet. canescent, deeply toothed, or jagged. Peduncles usually three-flowered ; 
Eneravincs.—Bot. Mag., t. 240; Sweet’s Geraniacew, t. 43, and | upper petals short, warted at the base; lower ones oval. (G, Don.) 
our fig. 2, in Pl. 15. 
Description, &c.—Though this plant is popularly known as Pelargonium tricolor, it has, in fact, only two 
distinct colours, and these are deep red and clear white. The two upper petals, which are red, have, however, a 
dark stain at the base, which is considered to make up the three colours. This species is more hardy than the 
tuberous-rooted kinds, but hardly so much so as the Pelargoniums commonly found in greenhouses. P. tricolor | 
was raised from seeds received from the Cape of Good Hope in 1791. |

OTHER SPECIES BELONGING TO SECT. V. 
P. ELATUM Sweet. 
This plant differs principally from the preceding species in growing much higher, and in the upper petals of 
the flowers being of a paler hue. Four hybrids were raised from this species by Sweet, and they appear, from the 
figures he has given of them, to have been ornamental; but they are all now lost to our gardens. 

SECT. VI—GRENVILLEA. 
Description, &c.—This section contains only one species, which was named in honour of Lady Grenville. 
There are only four fertile stamens, and five petals; the two upper ones on long claws, and much larger than the 
three lower ones, which are very small. The plant is tuberous-rooted, and has simple leaves. The flowers are of 
a pale blush, and the two upper petals have a dark spot in the centre of each. 
SECT. VIJI.—SEYMOURIA. 
Dxscription, &c.—This section contains only two species, the flowers of both of which have only two petals, 
distinct at the base, and abruptly reflexed in the middle. There are five stamens, all of which are fertile, and 
which grow together into a long straight tube. They have no stems, but turnip-like roots. The flowers of both 
species are purple. The section is named in honour of the Hon. Emily Seymour. 
SECT. VIIIL—JENKINSONIA. 
Secrionar Cuaracter.—Petals four or five, superior ones much | five or seven of which usually bear anthers, the sterile ones very short, 
larger than the rest, emarginate at the apex, streaked with lines. | and awl-shaped. (G. Don.) 
Stamens ten, ascending, spreading at the top, and pilose at the base, 
Description, &c.—The species belonging to this section are partly shrubs, and partly herbaceous plants. The 
leaves are generally very much cut, and the flowers are ornamental. In their botanical construction they vary 
considerably, some having four petals, and some five, and either five or seven anthers. The section is named in 
compliment to Mr. Jenkinson, but it was one of Sweet's genera.
