474 THE VEGETABLE WORLD. 
an indigenous species in France, often cultivated in gardens; its 
flowers are of various colours, yellow, purple, and white. e 
Chinese Primrose makes an agreeable ornament to our conserva- 
tories during the winter. 
The calyx of the Primrose flower is monosepalous, and forms a 
tube terminated at the summit by five lobes or teeth. The corolla 
is monopetalous and hypocrateriform ; its limbs present five lobes 
alternating with the teeth of the calyx; five stamens are inserted 
upon the tube of the corolla, and their two cells open from within 
by two longitudinal clefts. The pistil presents a superior ovary, 
surmounted by a more or less elongated style. The ovary is unilo- 
cular, and has in its interior a large central placenta : it is filled with 
a great number of ovules. The fruit is a capsule, with five valves, 
opening at the summit, through which the seeds, which are sup- 
plied with a fleshy albumen enveloping a straight embryo, are 
suffered to escape. | 
Next to the Primrose we will place the Cyclamen, so character- — 
ised frem its elegant corolla with reflex lobes, and by its sub- 
terranean stem, for it has no cereal stem, the root stem being 
sometimes so enlarged as to resemble a loaf of bread; it is @ 
favourite food with swine, whence the name of Sow’s Bread, not 
uncommonly given to it. We have also Lysimachia, with wheel- 
shaped corolla,and bitter astringent roots; one of them, the Yellow 
Loosestrife (L. culgaris), unfolds its large handsome flowers by the 
_ Sides of rivers and in shady watery places. 
Slightly removed from the Primroses are the Pimpernels (A”4- 
gallis) ; they have a round ovary, with a thread-like style, one 
a capsule, opening like a box with a lid. 7 
The remaining Perigynous orders, ranging from COXLIX. the 
JasMINACER, to CCLXV. the Lenrrpunariace%, although they 1- 
clude some interesting families of plants, our space compels us to — 
dismiss with little more than a brief enumeration. In this group 
we must include the Jasmines, chiefly inhabitants of tropical 
India, America, and Australia, two species only being natives of = 
the South of Europe.
