ANGUSTUltA CANELLA. 139 



been supposed to be the bark of the magnolia glauca ; but, with 

 more probability, it has heen since thought to be that of the brucea 

 antidysenterica *-, or brucea ferruginea of L'Heritier and Aitou f: 

 for the description of the bark of this tree, given by Mr. Bruce, agrees 

 very well with the cortex angusturae ; and as far as can be judged 

 by the bark of a living plant of this species, now growing in the 

 Royal Garden at Kew, this opinion is still further confirmed. 



During the last twelve years, in which the angustura bark has been 

 known as a medicine in this country, it has been successfully used in 

 the characters of a febrifuge, tonic, and astringent. In infermit- 

 tents it has been found equally effectual as Peruvian bark, and 

 generally more acceptable to the stomach j and in cases of diarrhea, 

 dyspepsia, scrophula, and great debility, it has been found to be an 

 useful remedy J.

Canella. 

 Canella alba. Woodv. 



The stem of this tree rises very straight, from ten to fifty feet in 

 height, and branched only at the top ; it is covered with a whitish 

 bark, by which it is easily distinguished at a distance from other 

 trees in the woods where it grows : the leaves are placed upon short 

 footstalks, and stand alternately : they are oblong, obtuse, entire, 

 of a dark shining green hue, and thick like those of the laurel : the 

 flowers are small, seldom opening, of a violet colour, and grow in 

 clusters at the tops of the branches upon divided footstalks : the 

 calyx is monophyllus, divided nearly to its base into three lobes, 

 which are roundish, concave, incumbent, green, smooth, membra- 

 nous, and persistent : the corolla is composed of five petals, which 

 are much longer than the calyx, sessile, oblong, concave, erect, and 

 two of them are somewhat narrower than the other three : the 

 nectary is pitcher-shaped, of the length of the petals, and supports 

 the anthers instead of filaments, which are wanting : the antherae
