are very ornamental plants, and, being all natives of the Cape of Good Hope, they all require a greenhouse in 
this countiy. They should all he grown in peat earth mixed with sand, and they are easily increased by cuttings. 
2.— POLYGALA BRACTEOLATA Lin. THE LARGE-BRACTED MILKWORT. 
Engravings. — Bot. Mag., t. 345 ; and om fig. 3, in PI. 3. 
Specific Character. — 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 
1713, but it is now very rarely to be met with. 
a— POLYGALA LIGULARIS Kev. THE TONGUE-LEAVED MILKWORT. 
Engraving. — Bot. Reg., t. 637. I spreading, glabrous. Branches villous. Bracteas permanent, equal. 
Specific Character. — Leaves ligulate-linear, rather 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 Rosemaiy ; 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. 
Engravings. — Bot. Mag., t. 1780; Bot. Reg., t. 150; and onr fig. I Specific Character.— Flowers crested, in long racemes, alternate, 
1, in PI. 3. I and rather distant. Leaves alternate, oblong-cuneate, glabrous. 
Description, &c. — 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. 
Engraving. — Bot. Reg., t. 669. | nated ; hranchlets clothed with appressed down ; bracteas equal, 
Specific Character. — Leaves obovate 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 wrs 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 shmb, growing three or four feet high, and of very easy cultivation. There are a great 
many varieties, among which, perhaps, may be reckoned P. grandijlora Lodd., which has very large bluish- 
purple flowers. 
6.— POLYGALA CHAM^BUXUS Lin. THE BOX-LEAVED MILKWORT. 
Engravings. — Bot. Mag., t. 316 ; and om fig. 2, in PI. 3. i Leaves oblong-lanceolate, mucronated. Racemes one to two-flowered; 
Specific Character. — Stem suflruticose, branched, procumbent. | keel of the flower crested. (^G. Don.) 
Description, &c. — This beautiful little plant is a native of mountainous places in woods, in vaiious 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 veiy apt to have
