apparently quite proof against the bitterest 

 winter. 



CuUwre <tc. as above. Increased by 

 seeds, cuttings, or layers. 



I. tenoreana. — A pretty perennial 3-6 

 in. higb, native of S.W. Europe. Leaves 

 somewhat fleshy, crenated, lower ones 

 obovate, narrowed at the base and fringed 

 with hairs; upper ones oblong linear. 

 Flowers in early summer, white changing 

 to purple, freely produced in umbellate 

 heads. 



Culture dc. as above. This species is 

 liable to perish in severe winters on cold 

 heavy soils. On well-drained sandy soil 

 it does weU, and is better treated as a 

 biennial than a perennial. It is easily 

 reproduced from seed sown as recom- 

 mended above. 



I, umbellata. — This is the well-known 

 pretty annual Common Candytuft, 6-12 

 in. high, native of S. Europe. Leaves 

 lance- shaped, pointed, lower ones serrated, 

 Tipper ones entire. Flowers in spring and 

 summer, very variable in colour, but 

 usually purple in terminal umbelg. Atro- 

 purpv/rea has dark crimson flowers ; 

 cornea, blush or pale flesh-coloured ; nana 

 purpu/rea, dwarf, deep purple ; purpurea 

 Klacima, dwarf, lilac-purple. There are 

 several other varieties mentioned in 

 catalogues, chiefly distinguished by the 

 colour of the flowers. 



Culture amd Propagation. — This 

 group of Candytufts likes a rich soil, and 

 produces the finest flowers in spring from 

 seeds sown in autumn. General cultiva- 

 tion &c. as above for annuals. 



I. violacea. — A dwarf annual, 3 in. 

 high, with stalked, spoon-shaped, bluntly 

 toothed or entire, ciliated leaves. Flowers 

 in summer, purple, in umbellate corymbs. 



Culture dc. as above. Increased by 

 seeds. 



HUTCHINSIA.— A genus with only 

 one or two species of small and rather 

 smooth annual herbs, having the lower 

 leaves usually in rosettes, and pinnately 

 lobed. Scapes several, ascending, leafy. 

 Flowers sub-ooryrabose, small, white, on 

 elongated braotless pedicels. 



Culture amd Propagation. — These are 

 pretty plants for the rock garden, edges 

 of borders &o., in sandy soU. They are 

 raised from seed like other annuals, either 

 in gentle heat about February and March, 

 afterwards pricking the seedlings out and 



hardening them off before placing in the 

 open air at the end of May ; or the seeds 

 may be sown in the open border from 

 AprU to the end of June for a succession 

 of flowers. 



H. alpina. — A pretty little alpine with 

 shining green leaves, and clusters of 

 small white flowers on stalks about 1 in. 

 high. 



CuUu/re dc. as above. 



H. petraea. — A more or less glabrous, 

 erect, delicate annual, native of hmestone 

 rocks in Britain and Central and S. 

 Europe, with lower leaves pinnate, and 

 masses of minute white flowers. 



Culture dc. as above. 



IBERIDELLA. — A genus containing 

 6 species of rather pretty herbs or under- 

 shrubs, often branched and woody at the 

 base, smooth, with alternate or opposite 

 entire leaves, those of the stem often 

 auricled, or cordately sagittate. Flowers 

 racemose, white or rose. 



I. rotundifolia. — A native of the 

 European Alps, 3-6 in. high, spreading, 

 densely tufted, with opposite, fleshy, 

 broadly ovate leaves. Flowers in early 

 summer, rosy-lilac, with a yellow eye, 

 fragrant, about J in. across, in erect, 

 cylindrical, crowded racemes. 



Culture and Propagation. — This 

 species is adapted for the rock garden, 

 and thrives in rather light sandy soil. 

 It may be increased by seeds sown as 

 soon as ripe in cold frames or in the open 

 border in April and May. Or the plants 

 may also be divided in early autumn, and 

 cuttings of the shoots may be inserted in 

 light sandy soil in a shaded border during 

 the summer months. 



TCH I H ATCH EWI A.— Agenus with 

 only one species : — 



T. isatidea. — A pretty Armenian rook- 

 plant about a foot high, with very hairy 

 oblong linear toothed leaves. The bright 

 rosy-ldac and vanilla - scented flowers 

 appear in May, and are borne in racemes 

 about a foot across on thick fleshy stalks. 



Culture and Propagation. — This 

 plant flourishes in ordinary well-drained 

 soil in the rook garden, and being a 

 biennial should be raised from seeds sown 

 in cold frames when ripe every year so as 

 to keep up a stock of plants. The young 

 plants may be transferred to the open air 

 in spring, or in autumn if large enough.
