THE LADIES' FLOWER-GARDEN 
22.— PHLOX NIVALIS, Lodd. THE SNOW-WHITE PHLOX. 
Engravings. Lodd. Bot. Cab. t. 1780; Swt. Brit. Flow. Gard. terminal, in threes. Leaves linear, fasciculate, recurved, ciliated at the 
t. 185 ; and onvfig. 5, in PI. 73. margin. Calyx hairy ; tube of the corolla twice as long as the calyx ; 
Specific Character. — Stem suffruticose, very much branched, pro- segments of the corolla obcordate, somewhat plicate, 
cumbent ; branches ascending, thickly covered with short hairs ; flowers 
Description, &c. — This is a very singular little plant, from the curious manner in which the branches are 
clothed with short recurved linear loaves, which give the plant a heath-like appearance when not in flower. 
The flowers are large, and of a snowy white. Tliey are produced in great abundance, and look exceedingly well 
on rockwork. The plant is a native of Carolina, whence it was introduced in 1820. It should be grown in sand 
or peat, and it is propagated by cuttings. 
23.— PHLOX SETACEA, Lin. THE BRISTLED-LEAVED PHLOX. 
Engravings.— Bot. Mag. t. 415 ; and our fig. 3, in PI. 73. 
Specific Character. — Leaves bristly, very smooth. Flowers solitary. 
Description, &c. — This is a very handsome species, from the large size and bright colour of the flowers. 
The stems are at first procumbent ; but they are ascending at the tip. The species is nearly allied to P. subulata, 
and requires the same treatment. It is a native of Carolina, and was introduced in 1788. It flowers in April 
and May, and it is propagated by cuttings. It is rather tender, and requires protection during severe winters. 
CHAPTER XXXVI. 
CONVOLVULACE^. 
Ovarium usually simple, two-four celled, rarely almost one-celled, 
or altogether one-celled ; sometimes the ovarium is double or quad- 
ruple; in each cell there is one or two erect ovula. Style usually 
simple, entire, or more or less deeply cleft ; rarely two. Stigmas 
acute, flattened or globose; in those with the simple style two-lobed. 
Fruit a capsule or a dry berry, one-four-celled ; cells one,two-8eeded. 
Capsule usually dehiscing valvatcly, rarely transversely. Seeds usually 
rounded on one side, and flattened on the other, inserted by the 
base, glabrous or villous ; having the testa usually black and hard. 
Albumen mucilaginous. Cotyledons foliaceous and corrugated. Radicle 
incurved, inferior. (G. Don) 
Character of the Order. — Calyx of five-sepals ; sepals perma- 
ment, equal or unequal, disposed in one, two, or three series, often 
enlarged round the fruit. Corolla monopetalous, hypogynous, regular, 
tubular, campanulate or funnel-shaped ; having the limb sometimes of 
five plaits, and sometimes of five lobes, which are twisted in aestivation. 
Stamens five, opposite the sepals, and therefore alternating with the 
lobes or plaits of the cor(dla, inserted more or less towards the bottom 
of the corolla ; filaments usually unequal, dilated at the base, some- 
times villous, naked, or furnished with scales, usually inclosed, rarely 
exserted ; anthers long, usually sagittate, and adnate at the base, 
often twisted afterwards. Nectarium or hypogynous disk annular, 
surrounding the ovarium in most of the species, more or less showy. 
Description, &c. — Most of the plants belonging to the order Convolvulaceae are herbaceous, either annuals 
or perennials ; occasionally becoming shrubby near the base, but very rarely having a woody stem. The stems 
are generally twining or creeping, and very seldom erect. The roots are frequently tuberous, and used in 
medicine ; and all the plants abound in a milky, acrid juice. The flowers are generally very showy, and the 
leaves simple and alternate. These plants are found in almost every part of the world. The name of Convol- 
vulus, from which that of the order is derived, signifies to entwine ; and refers to the habit of growth of 
the species.
