therefore most appropriate to transmit his name to pos- 

 terity. It grows in woods especially of Fir, in Scotland 

 and in one English station, namely, a plantation of 

 Scotch Firs in the parish of Hartburn, Northumberland. 

 The stem trails along the ground, arid bears at intervals 

 pairs of roundish, slightly crenate leaves. The flower- 

 ing stalks are erect, and bear each two pendulous bell- 

 shaped flowers, which are fragrant and of a delicate 

 pink colour. Fl. June, July. Perennial. 



ORD. XLIIL KUBIACELE. THE MADDER TRIBE. 



Calyx 4 6-lobed, or wanting; corolla 4 6-lobed, 

 wheel-shaped or tubular, regular ; stamens equal in 

 number to the lobes of the corolla, and alternate with 

 them ; ovary 2-celled ; style 2-cleft ; stigmas 2 ; pericarp 

 2-celled, 2-seeded. This order, taken in its widest 

 extension, is one of the largest with which we are 

 acquainted, containing more than 2,800 species, of 

 which some are of the highest utility to man, both as 

 food and medicine. Among the former, Coffea Ardbica 

 holds the first place. The seeds of this tree furnish the 

 coffee of commerce. Several species of Cinchona, a 

 South American family, furnish Peruvian Bark and 

 Quinine : and drugs of similar properties are obtained 

 from other plants of the same tribe. Ipecacuanha 

 is the powdered root of a small plant which grows in 

 damp, shady forests in Brazil. The wood of another 

 plant of this tribe, Evosmia corymbosa, is so poisonous, 

 that Indians have been poisoned by eating meat roasted 

 on spits made of it. Not a few, moreover, are noted 

 for the fragrance and beauty of their flowers. All the 

 above mentioned are natives of hot climates ; the 

 British species are very different, both in habit and 

 properties. They are herbaceous plants, with slender 

 angular stems, whorled leaves, and small flowers, pos- 

 sessing no remarkable properties, except that of con-
