OF ORNAMENTAL EXOTIC PLANTS. 15 
are very ornamental plants, and, being all natives of the Cape of Good Hope, they all require a greenhouse mm 
this country. They should all be grown in peat earth mixed with sand, and they are easily increased by cuttings. 
2.—POLYGALA BRACTEOLATA Lin. THE LARGE-BRACTED MILKWORT, 
Encravines.—Bot. Mag., t. 345; and our jig. 3, in Pl. 4. 
Sprciric Cuaracter.—Flowers crested, racemose. Bracts three-leaved. Leaves linear-lanceolate. Stem shrubby. 
Description, &c.—This plant is very different from the Polygalas usually seen in greenhouses, from its spear- 
like leaves, and dark crimson flowers. It is a native of the Cape of Good Hope, whence it was introduced in 
1718, but it is now very rarely to be met with. 
3.—POLYGALA LIGULARIS Ker. THE TONGUE-LEAVED MILKWORT. 
Encravinc.—Bot. Reg., t. 637. spreading, glabrous. Branches villous. Bracteas permanent, equal. 
Speciric Cuaracter.—Leaves ligulate-linear,! ather obtuse, crowded, | Racemes short, crowded. 
Description, &c.—This is a very curious species: the branches, with their thick leaves crowded together, 
bear some resemblance to those of the Rosemary; while the flowers, which are like those of the other Polygalas, 
are crowded together in clusters at the extremity of the branches. ‘The species is a native of the Cape of Good 
Hope, whence it was introduced in 1820. 
4,—POLYGALA SPECIOSA Sims. THE SHOWY POLYGALA. 
Eneravines.—Bot. Mag., t. 1780; Bot. Reg., t. 150; and our jig. Sreciric Cuaracter.—F lowers crested, in long racemes, alternate, 
1, in Pl 4. and rather distant, Leayes alternate, oblong-cuneate, glabrous, 
Description, &v.—This, though it is called the showy Polygala, is one of the least ornamental species of the 
genus. It is a native of the Cape of Good Hope, whence it was introduced in 1814; and, when grown in a 
conservatory, it forms a loose spreading shrub, upwards of six feet high. 
5.—POLYGALA MYRTIFOLIA Lin. THE MYRTLE-LEAVED POLYGALA. 
Eneravinc.— Bot. Reg., t. 669. nated ; branchlets clothed with appressed down; bracteas equal, 
Speciric Cuaracter.—Leayes oboyate or oblong, somewhat mucro- | permanent; pedicels shorter than the flowers. (G. Don.) 
Description, &c.—This very beautiful species is a native of the Cape of Good Hope, and was one of the first 
plants introduced from that country. It was cultivated here by the Duchess of Beaufort, a great patroness of 
greenhouse plants in the early part of the last century. The date of its introduction is 1707. The plant itself 
forms a slender, branched shrub, growing three or four feet high, and of very easy cultivation. There are a great 
many varieties, among which, perhaps, may be reckoned P. grandiflora Lodd., which has very large bluish- 
purple flowers. 
6.—POLYGALA CHAMABUXUS Zin. THE BOX-LEAVED MILKWORT. 
Encravines.—Bot. Mag., t. 316; and our Jig. 2, in Pl. 4. Leaves oblong-lanceolate, mucronated. Racemes one to two-flowered ; 
Sreciric Cuaracrer.—Stem suffruticose, branched, procumbent. | keel of the flower crested. (G. Don.) 
Description, &c.—This beautiful little plant is a native of mountainous places in woods, in various parts of 
Europe, particularly in Switzerland. As, however, in its native country, it is covered with snow during winter, it 
is, like many other Alpine plants, seriously injured by cold without snow; and hence it is very apt to have
