PELTARIA. — A genus consisting of 

 3 species of tall glabrous perennial herbs, 

 with entire leaves, the upper ones of 

 which are cordate-sagittate at the base. 

 Flowers more or less in corymbs, white. 

 Pods large. 



P. alliacea. — A pretty plant about 1 ft. 

 high, native of B. Europe, and emitting 

 a Garlic-like odour. The white flowers 

 appear in June, followed by flat, smooth 

 seed pods. 



Culture and Propagation. — It will 

 grow in any hght soil, and may be in- 

 creased by seeds or dividing the roots in 

 the same way as recommended above for 

 Iheridella. 



ISATIS. — A genus of annual, 

 biennial, or perennial smooth glaucous 

 or downy herbs with entire leaves, those 

 of the stems being sagittate. The flowers 

 are usually yellow and borne in loose 

 racemes. Sepals equal at the base. 

 Stamens free. Fruit-pod a linear, ob- 

 long, ovate, roundish or wedge-shaped 

 sUiqua. 



There are about 30 species in this 

 genus, the best known being the native 

 Dyer's Woad (I. tmctoria) so much in 

 use by the ancient Britons for staining 

 their bodies. With the exception of the 

 species described below, the others are of 

 no garden value. 



I. glauca. — A beautiful perennial 3-4 

 ft. high, native of Smyrna. The light 

 green furrowed stems are clothed with 

 glaucous - green oblong lance - shaped 

 leaves 6 in. long, having a whitish mid- 

 rib. The small clear light yellow flowers 

 appear in July, and are borne in immense 

 numbers in large loose branched racemes 

 which look very handsome and effective. 



Culture ami, Propagation. — This 

 species is not yet well known. It thrives 

 in ordinary good garden soil in warm and 

 sheltered positions in the flower border. 

 Being a true perennial it may be increased 

 by careful division in spring or early 

 autumn ; or by seeds sown in cold frames 

 when ripe or in spring. 



BOLEUM. — A genus with only one 

 species here described : — 



B. asperum. — An ornamental ever- 

 green shrub, 6-12 in. high, native of 

 France, covered with rather stiffish hairs, 

 and having alternate oblong-linear, entire 

 leaves, the lower ones somewhat divided. 

 Flowers in April, creamy yellow, in short 

 erect and elongated racemes. Sepals 



erect, equal at the base. The longer 

 stamens united in pairs. 



Culture and Propagation. — In severe 

 winters this plant would probably require 

 protection in northern parts of the country. 

 It grows well in ordinary soil, and may be 

 increased by seeds sown in a hotbed in 

 spring, or in the open border in summer. 

 Cuttings of the young shoots may also be 

 rooted in light sandy soil under a hand- 

 light during the summer , months. The 

 plants thus raised may be protected in 

 cold frames until favourable weather in 

 spring will permit of their being planted 

 out. 



CRAMBE (Sea Kale).— A genus with 

 16 species of herbs or undershrubs having 

 thickened rootstocks and branched and 

 glaucous smooth or hairy stems, furnished 

 with large and often pinnately cut leaves. 

 Flowers in elongated branched racemes or 

 panicles. 



Culture amd Propagation. — The Sea 

 Kale (C. ma/ritimia) is probably the best 

 known representative of the genus, and its 

 culture &c. is fully dealt with in the 

 Vegetable section of this work at p. 1121, 

 The species described below are the only 

 ones at present known of any value as 

 decorative plants. They are rather large 

 and coarse growing, but when in full 

 blossom are among the showiest and most 

 attractive of flowering plants, chiefly on 

 account of the immense numbers of 

 blossoms they produce. They flourish in 

 any garden soil and are more suitable for 

 wild parts of the garden in open sunny 

 spots, for association with such plants as 

 Heracleum giganteum, p. 469, Buph- 

 thalnvwm speciosum, p. 511, &c. They 

 ripen seeds freely and may be increased 

 by that means sown out of doors or in 

 cold frames as soon as ripe or in spring. 

 The roots may also be divided at the 

 latter season as growth is commencing. 



C. cordifolia. — A vigorous and deep- 

 rooting Caucasian perennial about 6 ft, 

 high, with tufts of large radical heart- 

 shaped lobed, wavy, and wrinkled leaves 

 12-18 in. wide. The white cross-shaped 

 flowers are produced in immense numbers 

 in June and early July, and are borne in 

 much - branched panicles, which stand 

 about 3 ft. above the foliage and are 

 4-6 ft. through, the branchlets spreading 

 horizontally, or drooping at the base. 



Culture Sc. as above. Grows well in 

 shade.
