DICENTRA 
The flowers are from 1 to 2 inches across, and appear in April and May. 
Introduced to England in 1680. 
cultivation Sanguinaria succeeds best in light sandy loam, or peat 
Its lowly stature entitles it to front rank In the border, but 
it should be given a sunny position, for it is only in sunshine that it opens 
its flowers. It is propagated by division of the rootstock, or by sowing 
the seed as soon as ripe in the open border. It is perfectly hardy. 
Bocconia (named after Dr. P. Boccone, a Sicilian botanical author) 
is another genus of this order. There are several species, of which the 
most frequently cultivated is Bocconia cordata, a stately plant growing 
to a height of from 5 to 8 feet, well-covered with boldly cut, deeply 
veined leaves, and small reddish-yellow flowers. These consist of two 
petal-like sepals, and a number of stamens, individually not at all strik¬ 
ing, but they are combined into a very large pyramidal panicle, which 
has a fine striking effect. It is seen to most advantage when planted in 
groups in wide borders, or in a bed on a large lawn. It is also a most valu¬ 
able plant for what is termed sub-tropical gardening. It flowers from 
May to July; but its appearance is by no means what one expects from 
a Papaveraceous plant. B. cordata was introduced from China in 1795. 
It is propagated by cuttings or suckers, and likes a rich loamy soil. 
DICENTRA 
Natural Order Fumariack®. Genus Dicentra 
Dicentra (Greek, dis, two, and kentron , a spur or goad). A genus of 
about a dozen species of hardy herbaceous plants, natives of North 
America and North-West Asia. They are all perennials, and have 
tuberous, fleshy, or fibrous roots. The leaves are much divided, and the 
flowers of singular form borne in racemes. The sepals are mere minute 
scales that drop off before the flower opens. There are four petals in 
two quite dissimilar pairs; the outer, concave, swollen at the base, and 
spreading acutely at the apex; the inner, slender, clawed, keeled at the 
back, and cohering at their tips. Stamens, six, in two bundles of three; 
ovary, one-celled. 
This genus of handsome plants is of comparatively 
ry ‘ recent introduction to the gardener. One species, Dicentra 
CucuUaria, was brought from the United States in 1731, but does not 
appear to have been at all widely grown; D . formosa was introduced
