BEAUTIFUL GARDEN FLOWERS. 
florets, are very attractive. Two forms, one called 
atrosanguinea with deep blood-red blossoms, the other 
nigra sjpeciosa, with deep velvety crimson ones, are 
both remarkably conspicuous when in bloom. 
Of the biennial and perennial species C. lanceolata 
and G. grandiflora are well-known. The first named is 
a true perennial, 1 to 3 feet high, with lance-shaped 
leaves, and bright golden-yellow flowers ; C. grandi- 
flora, although it can be continued year to year by 
means of planting non-flowering basal and side shoots, 
is nevertheless a biennial, and it is better to raise the 
plants from seeds one year to flower the following. 
In appearance, the flowers of both species are similar, 
but those of 0. grandiflora shown on Plate 18, fig. 52, 
are the larger as a rule. 
CORYDALIS. — Of the 70 species in this genus, 
most may be ranked as weeds. The common yellow 
Fumitory (0. lutea ) is a charming little perennial, 1 to 
2 feet high, with grey-green finely-cut leaves, amongst 
which the “ spurred ” yellow blossoms nestle from 
early summer till the approach of winter. It is easily 
increased by seeds, or division of the rootstocks, and 
may be regarded as a first-class rock plant. Similar 
to C. lutea, but larger in leaf and blossom, and looser in 
habit, is the recently introduced G. thalictrifolia from 
Central China. It seems to be perfectly hardy, and 
seeds quite freely, while the yellow blossoms appear 
for several months. C. Wilsoni is another new species, 
dwarf in habit. Ordinary garden soil will suit any 
of the Corydalis, annual or perennial. 
COSMOS bipinnatus. — A graceful Mexican annual 
about 3 feet high, with finely-cut feathery foliage, and
