64 FLOWERS OF GARDEN AND GREENHOUSE 
they are mature, and before the wood has begun to harden. Insert them 
in sandy soil, either in a frame or under a bell-glass in the open-air, and 
they will soon send forth roots. It is advisable to leave them where 
they are until the spring, when they may be planted out into permanent 
positions in the herbaceous border, or in the very forefront of the 
shrubbery. Such of the shrubby forms as have a tendency to trail may 
also be increased by layering. Certain of these—7. gitoaltarica and 7 
8axatilis, for example—sometimes get untidy from this trailing habit, 
and must either be pegged down or cut back. I. gibraltarica does best 
on a well-drained rock-garden in light soil, where its struggling pro¬ 
pensity is no disadvantage. 7. tenoreana likewise demands a well- 
drained soil and a sheltered position, otherwise it will die off in winter 
7. gibraltarica var. hybrida makes a capital bedding plant. 
Description of The Gibraltar Candytuft (7. gibraltarica) is shown on 
Plates 29 and so. Plate 29, the branches in their natural sub-erect attitude, 
the leaves and flowers of the natural size. Fig. 1 is an enlarged drawing 
of a single blossom, to show more clearly the disparity in the size of the 
petals,their characteristic direction, and the half-erect attitude of the sepals- 
Fig. 2 is a section of the enlarged flower, and Fig. 3 is the ovary and style. 
Plate 30 represents the annual species (A) 7. urnbdlata and (B) 7. 
amara. The figures of the details are drawn from 7. umbeUata , and 
depict: (1) a flower from the centre of the corymb; (2) one from the cir¬ 
cumference with the larger petals more spreading; (3) a section of the 
same; (4) the seed-vessel with its homed wings; (5) the same enlarged 
and opening to discharge the seed; (6) the seed, natural size and enlarged; 
(7) the seedling. On comparing 4 or 5 with B, considerable difference in 
the form of the seed-vessel will be seen to exist between the two species. 
MIGNONETTE 
Natural Order Resedace^:. Genus Reseda 
Reseda (Latin, resedo, to quiet, the plant having formerly been thought 
to act as a sedative). A genus of about twenty-six alternate-leaved 
herbs, natives of Europe, Western Asia, and North Africa, including the 
British species. The flowers are irregular, and the stamens more 
conspicuous than any other part. The calyx is from four, to seven- 
parted, irregular, remaining attached to the seed-vessel. The petals 
vary from four to seven, attached beneath the ovary (hypogynous), and 
are cut up into a number of segments, the upper one with a membranous
