THE LADIES’ FLOWER-GARDEN 
2.— POLEMONIUM SIBIRICUM, D. Don. THE SIBERIAN POLEMONIUM, 
SvNONYMEs. — P. lacteum, Leh. ; P. dissectum, Rchb. 1 Specific Chaeicter. — Leaves bipinnate, pubescent; leaflets linear- 
Engravings. — Sweet’s Brit. Flow. Gard. t. 182 ; and our Jig. 1, i“ lanceolate, acute ; corymb paniculate, crowded; calyx hairy ; segments 
PI. 73. 1 of the corolla broadly ovate, acute. 
Description, &c. — This is a very handsome species. The stems are angular ; several rising erect from the 
same plant, and growing from a foot to eighteen inclies high. Tlie leaves are pinnate ; and the leaflets are 
either pinnate or pinnatifid, being frequently crowded together, so as to appear tufted. The flowers are white, 
and much smaller than those of the other species, though they are very handsome, from their abundance, and 
the manner in which tliey are disposed. The species is a native of Siberia, whence it was introduced in 1800. 
It will grow freely in any common garden soil that is light and sandy, but it requires an open situation, where 
it can have abundance of free air. 
3.— POLEMONIUM RICHARDSONII, Graham. DR. RICHARDSON’S GREEK VALERIAN. 
with numerous leaflets ; pinnae ovate, rotund, mucronate, pubescent 
beneath ; flowers corymbose, naked ; segments of the corolla obtuse, 
creuulated ; roots subfusiform, very long. 
Synonymes. — P. speciosum, Fisch. ; P. coeruleum, var. nanum, 
Hook. 
Engravings. — Bot. Mag. t. 2800 ; and oxa Jig. 3, in Plate 73. 
Specific Character. — Stem hairy, angular, erect ; leaves pinnate. 
Description, &c. — The root of this plant is very remarkable, as it is frequently three or four feet long, and 
as thick as a finger, though the plant is not more than six inches high. The root is also branched at the tip like 
a grappling-iron, as though to take a firm hold of the loose sand in which the plants generally grow. The root 
is yellow, and much resembles that of licorice. The plant is a native of the Great Bear Lake, wliere it was 
found by Dr. Richardson, in 1825, growing in 66° north latitude. It wull, of course, bear any degree of cold in 
this country ; but it is easily injured by an excess of moisture, and requires a deep sandy soil. 
4.— POLEMONIUM HUMILE, Ram. et Schult. THE DWARF GREEK VALERIAN. 
Synonymes. — P. villosura, Swt.; P. lanatum, Fisch. ; P. coeru- 
leum, P Gmel. ; P. gracile, Dougl. ; P. Richardsonii, G. Don. 
Engravings Bot. Reg. t. 1304 ; Swt. Brit. Flow. Gard., t. 266 ; 
and our Jig. 2, iu Plate 73. 
Specific Character. — Stem pilose, angular, erect ; leaves with 
many pairs of leaflets, which are ovate, bluntish, pilose on both sur- 
faces ; flowers a little panicled, drooping ; segments of the corolla 
roundish, crenulated. (G. Don.) 
Description, &c. — This species, like P. Richardsonii, has the root excessively elongated. The stem is 
erect, and covered with soft hairs ; the petioles are slightly winged and dilated at the base, which is tinged with 
purple. The leaflets are hairy on both sides, and delicately fringed at the margin. The flowers have rather a 
disagreeable smell. This species is very nearly allied to P. Richardsonii, but it is not so handsome. It was 
raised from seeds eollected by Dr. Richardson during the Arctic expedition, which took place about 1828, and 
it has been also found in Siberia. It should be grown in poor gravelly soil, kept moist ; as, when grown in 
rich mould, it produces more leaves than flowers. 
5.— POLEMONIUM MEXICANUM, Cerv. THE MEXICAN POLEMONIUM. 
Engraving. — Bot. Reg. t. 460. 
Specific Character. — Leaves pinnate, with many leaflets ; terminal, one or three lobed ; flowers nodding ; calyx covered ivith viscid hairs. 
Description, &c. — This species is a native of Mexico, whence it was sent to Madrid in 1815. The flowers ■ 
are small, and more tubular than those of most of tlie other species, but they do not possess much beauty. The ■ 
plant is. indeed, scarcely worth the trouble of cultivating, as it is rather tender.
