THE LADIES’ FLOWER-GARDEN 
22.— PHLOX NIVALIS, Lodd. THE SNOW-WHITE PHLOX. 
Engravings.— Lodd. Bot. Cab. t. 1780; Swt. Brit. Flow. Gard. 
t. 185; and onvfig. 5, in PL 75. 
Specific Character.— Stem suffruticose, very much branched, pro- 
cumbent ; branches ascending, thickly covered with short hairs ; flowers 
terminal, in threes. Leaves linear, fasciculate, recurved, ciliated at the 
margin. Calyx hairy ; tube of the corolla twice as long as the calyx ; 
segments of the corolla oboordate, somewhat plicate. 
Description, &c. — This is a very singular little plant, from the curious manner in which the branches are 
clothed with short recurved linear leaves, which give the plant a heath-like appearance when not in flower. 
The flowers are large, and of a snowy white. They are produced in great abundance, and look exceedingly well 
on rock work. 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 PL 75. 
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 1 788. 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^. 
Character of the Order. — Calyx of five-sepals ; sepals perma- 
raent, 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 corolla, inserted more or less tow-irds 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. 
Ovarium usually simple, two-four celled, rarely almost one-celled, ji 
or altogether one-celled : sometimes the ovarium is double or quad- j 
ruple ; in each cell there is one or two erect ovula. Style usually | 
simple, entire, or more or less deeply cleft ; rarely two. Stigmas j 
acute, flattened or globose ; in those with the simple style two-lobed. j 
Fruit a capsule or a dry berry, one-four-celled ; cells one,two-seeded. !| 
Capsule usually dehiscing valvately, rarely transversely. Seeds usually j| 
rounded on one side, and flattened on the other, inserted by the i 
base, glabrous or villous ; having the testa usually black and hard. ] 
Albumen mucilaginous. Cotyledons foliaceous and corrugated. Radicle I' 
incurved, inferior. (G. Don.) ' 
Description &c. — Most of the plants belonging to the order Convolvulaceie 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.
