CORIANDER is the seed-like fruit of Coriandrum 

 sativum, Linn., an umbelliferous annual of southern 

 Europe. The plant grows 1 to 3 feet high, glabrous, 

 strong-smelling, with leaves divided into almost thread- 

 like divisions, and small white flowers. The plant is 

 easily grown in garden soil. It occasionally becomes 

 spontaneous about old yards. The seeds (fruits) are 

 used as seasoning and flavoring in pastries, confections 

 and liquors, although they are less known in this coun- 

 try than caraway. The plant is sometimes grown in 

 American gardens with sweet herbs and other things. 



CORIANDRUM: Coriander. 



CORIARIA (corium, skin, leather; a shrub used 

 for tanning leather was described as frutex coriarius, 

 by Pliny). Coriaridcese. Shrubs or perennial herbs 

 grown chiefly for their ornamental fruits. 



Leaves deciduous, entire, 3-9-nerved, opposite and 

 distichous: fls. polygamous-monoecious in slender 

 racemes, small; petals and sepals 5; stamens 10: fr. 

 berry-like, consisting of 5 1-seeded nutlets inclosed by 

 the enlarged and colored petals. About 8 species in 

 Himalayas and E. Asia, Medit. region, N. Zeal, and S. 

 Amer. Ornamental shrubs or herbs, with slender arch- 

 ing branches imitating pinnate Ivs., and with very 

 showy yellow, red or black fr. The Ivs. of some species 

 are used for tanning leather; the frs. are poisonous 

 in some species, edible in others. C. japonica has 

 proved hardy with slight protection in Mass., and C. 

 terminalis seems to be of the same hardiness ; the other 

 species are more tender. They grow in almost any 

 good garden soil, and prefer sunny position. Prop, 

 readily by seeds and greenwood cuttings in summer 

 under glass; also by suckers and layers. 



japonica, Gray. Fig. 1057. Shrub, 2-3, sometimes to 

 10 ft.: branches quadrangular: Ivs. nearly sessile, ovate 

 or ovate-lanceolate, 3-nerved, smooth, 2-4 in. long: fls. 

 in axillary racemes from the branches of last year: fr. 

 becoming bright red in summer, changing to violet-
