GENUS I. 
PYROLA, Lin. THE WINTER-GREEN. 
Lin. Syst. DECANDRIA MONOGYNIA. 
Generic Character. — Calyx five-parted. Petals five. Capsule five-celled, opening at the angle. 
Description, &c. — The common winter-green is a British plant. There are indeed several species that are 
natives of Britain ; but the only two kinds that are sufficiently ornamental to be worth cultivating in a flower- 
garden, are two of the American species. The word Pyrola, is said to be a diminutive of Pjrus a Pear-tree, from 
a slight resemblance in the leaves of the winter-green to those of some kinds of pears. 
1.— PYROLA UiMBELLATA, Lin. THE UMBELLATED WINTER-GREEN. 
Synonymes. — Chimaphila corymbosa, Pursh.; C. umbellata, Dec. I Specific Character. — Flowers in umbels. Stigma sessile, 
Engravings. — Bot. Mag. t. 778 ; and our fig. 1, in Plate 68. I entire. 
Description, &c. — This very pretty little plant, though common in many parts of Europe, Asia, and America, 
particularly in the latter country, has never yet been found wild in Great Britain. It begins to flower in June, 
and continues in blossom till the end of autumn. It should be grown in a situation sheltered from the sun, and 
it requires to be frequently watered. It was introduced from North America in 1762. 
-PYROLA MACULATA, Lin. THE SPOTTED-LEAVED WINTER-GREEN. 
'Synonymes. — P. marylandica. Pet.; P. mariana, Pulk.; Chima- 
phila maculata, Dec. 
Engraving. — Bot. Mag. t. 897. 
Specific Character. — Leaves lanceolate, rigidly serrated, discoloured 
on the face. Scape two or three-flowered. Stigma nearly sessile, 
hemispherical. 
Description, &c. — This species is distinguished from the last by the leaves, which are broader, more rigid, 
and sharply pointed ; they are marked on the face with a pale line covering the mid-rib, and branching over the 
principal veins. Tlie stem is twisted, and the leaves, though opposite, are thus generally turned to one side and 
crowded towards the upper part. The petals are reflexed, and the base of the filaments is deeply fringed. The 
species forms a dwarf plant from 6 inches to a foot high ; and it has a very striking and lively appearance from 
its white flowers, bright-red stems, and singularly marked leaves. It is a native of North America, and was 
introduced in 1752. 
CHAPTER XXX. 
APOCYNEaE. 
Character of the Order. — Calyx five-cleft, permanent. Corolla 
monopetalous, hypogynous, regular, five-lobed, imbricate in aestivation, 
deciduous. Stamens five, epipetalous, alternating with the segments of 
the limb of the corolla ; anthers two-celled, dehiscing lengthwise ; 
pollen granular. There is sometimes only one ovary ; but occasionally 
there are two, and therefore the styles are one or two, but there is 
always only one stigma : the ovaries, for the most part, are many-seeded. 
Fruit follicular, drupaceous or baccate, or many-seeded, solitary or 
twin. Seeds usually albuminous. Embryo foliaceous, with an incon- 
spicuous plumule. 
Description, &c. — The plants belonging to this order are readily known by the twisted direction of the 
corolla of their flowers, which has been compared to the rays of St. Catharine’s wheel. The juices of these 
plants, like those of Lobeliaceae, are milky, and extremely poisonous. The flowers are generally handsome. 
Most of the species are trees and shrubs, and by far the greater part are natives of hot climates ; but three of the 
genera contain a few hardy perennials.
