Shrubby Dalea. Shrub. 



Cult. All the species of this genus grow best in a mixture of 

 loam and peat, and the shrubby and perennial kinds are easily 

 increased by young cuttings planted in sand, with a hand-! 

 placed over them ; those of the stove species in heat. The seeds 

 of annual kinds should be sown in pots, which should be placed in 

 a hot-bed, and the plants separated and planted into other pots 

 singly when they have grown a sufficient size for that pur- 

 pose, and some of them may be planted out into the open border 

 in a warm sheltered situation, where they will probably ripen 

 their seeds. None of the species are worth cultivating except 

 in botanical gardens. 



CI. GLYCYRHPZA (from yXu^e, glycys, sweet, and pifa, 

 rltiza, a root; the sweetness of the root of liquorice is well 

 known). Tourn. inst. 210. Lin. gen. 882. D. C. prod. 2. p.

 cleft, bilabiate ; lobes, especially the 2 superior ones, joined

 Stamens diadelphous. Style filiform. Legume ovate or oblong, 

 compressed, 1 -celled, 1-4-seeded. Perennial herbs, with long, 

 perpendicular, sweet roots, impari-pinnate leaves, axillary 

 racemes of blue, violaceous, or white flowers. This is the genus 

 to which the various kinds of liquorice belong.

 and somewhat clammy beneath, as well as the branches ; stipulas 

 wanting ; spikes or racemes of flowers pedunculate, shorter than 

 the leaves; flowers distant; legumes glabrous, 3-4-seeded. 

 7/ . H. Native of the south of Europe, from Spain to Tauria, 

 also of China, and cultivated in France, Italy, Germany, and 

 England for the sake of its roots. Lani. ill. t. 625. f. 2. Wood, 

 med. bot. 458. t. 167. G. lae'vis, Pall. itin. ed. gall, append, 

 no. 364. Liquiritia officinalis, Moench. 1. c. Roots long, per- 

 pendicular. Stem only terete at the apex. Leaves usually with 

 5 pairs of leaflets. Flowers pale-blue. The name liquorice, 

 according to Du Theis, is said to be a corruption of the French 

 word Reglisse, which is itself a corruption of Gli/ci/rlnza. It is 

 more probable that the name liquorice has been given on account 

 of the quantity of liquor the roots contain. Liquorice is much 

 cultivated in Spain, and since Elizabeth's time has been grown 

 in different parts of England. The soil most congenial to the 

 growth of liquorice is a deep sandy loam, trenched by the spade 

 or plough, or with the aid of both, to 2\ or 3 feet in depth, 

 and manured if necessary. The plants are procured from old 

 plantations; and consist of the side shoots which have eyes or 

 buds. These may be taken off either in autumn, when a crop 

 of liquorice is taken up for use, and laid in earth till spring, or 

 taken from a growing plantation as wanted for planting. The 

 planting season may be either October, or February, or March. 

 In general the latter is preferred. The plants are dibbled in the 

 rows 3 feet apart, and from 18 inches to 2 feet in the row, ac- 

 cording to the richness or poverty of the soil. The after culture
