XXIX. RUTACEyE— Rue Order 



A large order containing about 650 species of shrubs or trees, very rarely 

 herbs, remarkable for having numerous glandular spots on the leaves and 

 flowers, often containing pungent, strongly scented, bitter juices. Leaves 

 without stipules, often opposite, simple or often compound, 1-3-5-foliolate or 

 pinnate, very often entire, occasionally serrulate. Inflorescence various, 

 very rarely spicate or umbellate, usually cymose and axillary. Elowers 

 usually hermaphrodite. Sepals 4-5, imbricate, free or united. Petals 4-5, 

 hypogynous or perigynous, broadly imbricated, rarely valvate. Stamens 

 inserted at the base or on the edge of the disc, 4-5, or 8-10, rarely fewer or 

 more, free, or rarely cohering or united to the petals. Styles short or long, 

 distinct or connate. Fruit a capsule or berry, rarely a drupe. 



RUTA (Bub).— A genus of about 40 

 species of strong-smeUing perennial herbs 

 or undershrubs with round, branching 

 stems, and alternate, simple, 3-foliolate, 

 pinnatisect or decompound leaves. 

 Flowers yellow or greenish, usually 

 cymose. Calyx 4-5-lobed or parted, 

 persistent. Petals 4-5, often toothed or 

 ciUated, imbricated. Disc thick, urn- 

 shaped, with 8-10 glands or pits. Stamens 

 8-10 inserted at the base of the disc, one 

 short, one long, alternately. 



Culture and Propagation. — The Eues 

 thrive in light, rich soil, but only a few 

 are of any garden value. They may be 

 increased by seeds or cuttings in a shady 

 border. The seeds may be sown out of 

 doors as soon as ripe or in spring, after- 

 wards pricking the seedlings out about 6 

 in. apart when well above the surface. 

 As the plants increase in size they require 

 more space, but transplanting shoiddonly 

 be done in mild weather in spring or 

 autumn. Cuttings of the ripened shoots 



will root freely in autumn, especially if 

 placed in a cold frame or under a hand- 

 light. Sometimes old bushy plants may 

 be divided. Once established in a garden 

 the Eues may be allowed to look after 

 themselves for years. If cut back every 

 two or three years, new and vigorous 

 shoots will be developed. 



R. albiflora {Bcenninghausenia albi- 

 flora). — An elegant downy plant 2 ft. 

 high, native of Nepaul. Leaves very 

 much cut and finely divided, glaucous, 

 pubescent. Flowers borne in great 

 profusion from July to September, white ; 

 petals entire, shorter than the stamens.

R. graveolens (Common Rue ; 

 Countryman's Treacle ; Herb of Grace). 

 A well-known glaucous perennial 2-3 ft. 

 high, native of S. Europe, found in almost 

 every garden, no doubt chiefly on account 

 of its medicinal virtues. Leaves much 

 divided into oblong-obovate segments.
