Branches slightly quadrangular, smooth, except when young, at 

 which time they are covered with a slight hairiness, especially between 

 the angles. Leaves obovate-lanceolate, acute, not shining; neither 

 thin nor coriaceous, smooth on both sides except at the axils of the 

 veins on the underside. Panicles naked, terminal, thyrsoid, narrow, 

 with spreading distant rather compressed branches, covered with dense 

 short spreading hairs. Calyx quite smooth, with a shallow 5-toothed 

 limb. Corolla pink. It does not appear that the bark of this, which in 

 Peru is commonly called Asmonich, is now employed in medicine. The 

 Indians use its beautiful flowers to adorn their temples and the images 

 of their saints. Poppig found it about Cuchero where it "occurs not 

 unfrequently ; it is a highly beautiful tree, which in its size and mode of 

 ramification may be justly compared with the white Beech of Europe, 

 It is adorned in July with innumerable pale violet flowers, and in its 

 growth, circumference of stem, and hardness of wood, differs greatly from 

 all the other Cinchonas, the trunk seldom exceeding from 6 to 12 inches 

 in diameter. The name of Palo de San Juan refers to the flowering 

 season. Of the bark no use is made, for no one supposes it to belong 

 to the Cinchonas; but there can be little doubt that their peculiar 

 properties would be found, on examination, to exist in the thin and 

 smooth bark of its riper branches." 



COSMIBUENA. 



Calyx 5-toothed, campanulate, deciduous. Corolla with a long 

 curved tube, and a 5-lobed limb, which is imbricated in aestiva- 

 tion. Anthers oblong, subsessile, exserted. Stigma bipartite. 

 Capsule oblong, taper, 2-celled, somewhat 4-valved, dehiscing 

 from the apex, and dividing the septa. Seeds girded by a lace- 

 rated wing. Smooth South American Trees. Leaves ovate, 

 short stalked. Stipules large, oval, obtuse, erect, deciduous. 

 Flowers long, terminal, white.
