adapted for pot culture and greenhouse decoration. (B. M. 3108; 
S. B. F. G. ser. ii. 172.) 
N. rivularis (brook-loving).* f. white, with a yellowish, and, 
sometinies, a rosy tinge; corolla bell-shaped, about lin. across, 
with a very slender tube, lin. to 24in.long. July. l. very variable

matted, slender, smooth, creeping and rooting. La Plata, 1866. 
2 A handsome hardy perennial when well grown ; moisture and a 
little shade being the chief conditions required. In bare places, or 
the more moist parts of rockwork, it may be grown with capital 
effect ; but the patches should be broad. It also forms a good 
surfacing subject for leggy plants or shrubs. Propagation is best 
effected by divisions in spring, just as the new growth com- 
mences. (B. M. 5608.) 
N. Veitchii (Veitch’s). f. pale lilac, with a very slender corolla 
tube, lin. long. J. ovate-oblong. Stems slender, branching, 
prostrate. South America, 1866. Greenhouse. (B. M. 5589.) 
NIGELLA (a diminutive from niger, black; referring 
to the colour of the seeds). Devil-in-the-Bush; Fennel 
Flower; Love-in-a-Mist, Including Garidella. ORD. 
Ranunculacee. A genus comprising about half-a-score 
species of curious, hardy, erect-growing annuals, inhabit- 
ing.the Mediterranean region and Western Asia. Flowers 
white, blue, or yellowish; calyx of five petal-like deciduous 
sepals; petals five, two-lipped, with a hollow, necta- 
riferous claw. Stem leaves alternate, cut into very 
narrow, sub-pinnate segments. Nigellas are of the 
easiest culture in any moderately good garden soil. Seeds 
should be sowa im March or April, in the open border, 
in light soil, and the seedlings thinned out to 6in. apart. 
The species most generally grown are N. damascena and 
N. hispanica.

should be partially or nearly submerged in a tank in 
which tropical aquatics are cultivated.
