18.— PHLOX CANADENSIS, Sweet. THE BLUE CANADIAN PHLOX. 
Enorivimss.— Sweet's Brit. Flow. Qard., t. 221 ; and oni Jig, 3, in 
PI. 72. 
Specific CHiBiCTER.— Stems erect, subpubescent; lower leaves 
ovate, upper ones broadly lanceolate ; corymbs few-flowered, compact ; 
segments of the calyx subulate-linear ; segments of the corolla broadly 
obcordate ; tube curved, longer than the calyx. 
Description, &c. — The plant grows in a thick tuft, each root producing a great many erect branches. 
The leaves are smooth, but slightly fringed with short hairs round the margin. The flowers are blue, tinged 
with lilac, and are disposed in small, few-flowered panicles. The species is a native of Canada, whence it was 
introduced in 1826, and it is quite hardy in British gardens, where it flowers from May to October. It is 
generally increased by dividing the roots. 
19.— PHLOX DIVARICATA, Lin. THE SPREADING-FLOWERED PHLOX. 
Synontmcs. — Lychnidea Virginiana, Pluk. ; the early-flowering Leaves broadly-lanceolate, upper ones alternate. Flowers in a loose. 
Phlox. spreading panicle; segments of the corolla somewhat wedge-shaped, 
Ehgiuviso Bot. Mag., t. 163. bifid ; tube curved. 
Specific CHiiucTEtt. — Stem branched, spreading ; peduncles twin. 
Description, &c. — A very handsome species of Phlox, with large, pale-blue flowers. It seldom exceeds a 
foot in height, and produces its flowers in great abundance in April and May. It does not, however, continue 
so long in flower as most of the other species of the genus. It is a native of North America, and was introduced 
in 1746. 
§ 3. Leaves narrow. 
at the base, very smooth, ciliated at the margin. Segments of thf 
calyx linear, acute ; segments of the corolla cuneate, obcordate ; tube 
hairy, erect, twice as long as the calyx. 
20.— PHLOX PROCUMBENS, Lehm. THE PROCUMBENT PHLOX 
Enoiuvings. — Sweet's Brit. Flow. Card., 2d. ser., t. 7 ; and our 
fig. 2, in PI. 73. 
Specific Character. — Stem procumbent, branched ; branches 
ascending, and slightly hairy. Leaves lanceolate, acute, attenuated 
Description, &c. — A dwarf plant, with numerous procumbent stems, each generally dividing into several 
branches at the extremity, and frequently sending out roots at the joints near the base. The flowers whi^h 
terminate the branches can scarcely be said to form a panicle, there seldom being above two or four to each 
branch. The plant is a native of North America, whence it was introduced in 1829, and it flowers in May and 
June. It is propagated either by cuttings, or by dividing the root. 
21.— PHLOX SUBULATA, iin. THE AWL-LEAVED PHLOX. 
Enohavings. — Bot. Mag. t. 411 : and our Jig. 4, in PI. 73. 
Specific Character. — Leaves subulate, hairy. Flowers terminal, sometimes twin. 
Description, &c. — This is a very pretty little species, admirably adapted for rockwork. Its stems are 
procumbent, and when left to themselves either hang down in a very graceful manner, or trail on the ground. 
The flowers are produced in great abundance and are very pretty, as they are generally of a delicate pale pink, 
with a dark eye. The stems are also pink. The species is a native of Virginia, whence it was introduced in 
1786. The flowers are produced in April or the beginning of May,- and are easily injured by the cold winds 
which sometimes prevail at that season. It is always propagated by cuttings, as the root descends, and will not 
bear dividing.
