238 THE LADIES' FLOWER-GARDEN 
1.— PLATYCODON GRANDIFLORA, A. Dec. THE LARGE-FLOWERED PLATYCODON 
STKOiryMEd. — Camp, grandiflora, Jacq. ; C. gentianoides, Lam.\ I fig.^, in PI. 61. 
Wahlenbergia grandiflora, Schred. Specific CHAHACTEa. — Smooth. Leaves ovate-lanceolate, acuminate, 
Enoratings. — Sweet's Brit. Flow. Gard. series 2, t. 208 ; and our | sharply serrated. Capsule five-celled. 
Description, &c. — The leaves and stems of this plant are of a dull glaucous green ; the stems are very 
slender, and generally one-flowered, but occasionally they become branched, and bear several flowers. The 
leaves are rather long and sharply serrated. The flowers are of a very dark, rich blue ; and they are large and 
so widely spreading, as to be rather cup-shaped than bell-shaped. They are very handsome, and in fact the 
whole plant is one of the most showy of the order. It is a native of Siberia, and of course quite hardy ; but, 
though introduced so long ago as 1782, it is rarely seen in gardens : the reason of this is probably, because it is 
very difficult to propagate, as, if any of the roots should be broken or wounded in dividing them, they discharge 
so much of the milky juice in which they abound, as very soon to rot the plant. For the same reason, it is very 
difficult to strike by cuttings, as they also bleed profusely ; and it rarely produces perfect seeds. It flowers in 
July, when the buds, before they expand, bear so strong a resemblance to little balloons, that the plant has been 
sometimes called the Balloon Plant. It should be grown in a mixture of peat and loam, in a dry situation. 
GENUS IX. 
WAHLENBERGIA, Schrad. THE WAHLENBERGIA. 
Lin. Spat. PENTANDRIA MONOGYNIA. 
Generic Character. — Calyx three or five-cleft. Corolla three or 
five lobed at the apex, rarely divided to the middle. Stamens three or 
five, free ; filaments rather broadest at the base. Style, inclosed, 
0, but most 80 towards the upper part. Stigmas two or five. 
Ovarium combined with the tube of the calyx. Capsule two or five- 
celled, each opening by a valve at the apex. Seeds very numerous, 
and exceedingly small. 
Description, &c. — This genus was named after Dr. Wahlcnberg, the author of the Flora Lapponica. It 
consists of several species which were formerly included in the genus Campanula, but which have a more 
spreading limb than the species still included in that genus. The common British ivy-leaved Campanula will 
give an idea of the general shape of the flowers. The following species are those most generally cultivated in 
gardens. 
l._ WAHLENBERGIA GRACILIS, A. Dec. THE SLENDER WAHLENBERGIA. 
Synonvmes. — Camp, gracilis, Forst, ; C. vincaeflora, Vent. ; C. 
capillaris, Lodd. 
Engravings. — Bot. Mag. t. 691 ; Bot. Cab.t. 1406; and oxLtfig, 6, 
in PI. 61. 
Specific Character. — Leaves linear-lanceolate, obsoletely semted. 
Stem branched. Flowers solitary, terminal. 
Description, &c. — A graceful little plant, with many very slender stems, each about six inches high, and 
each producing a little panicle of flowers, which continue expanded all the summer. The species is a native of 
New South Wales, and was introduced in 1794. It is a biennial, requiring the usual treatment of such plants. 
It is easily propagated by seeds, which it produces in great abundance. It succeeds best when grown in loam or 
peat ; and it is also occasionally propagated by cuttings. 
W, GRAMINIFLORA, Alph. Dee. 
A native of Sicily, introduced in 1816. It is a dwarf plant, with grass-like leaves, and tufts of blue flowers, 
the filaments of the stamens of which are white, and the anthers yellow. It flowers from May to July.
