CINCHONACEJE. 



leafless thyrse, whose branches are rather erect, and merely downy, not 

 woolly. Calyx-tube covered with very close short tomentum; limb 

 pubescent, smooth at the edges, with oval imbricating obtuse teeth. 

 Corolla tomentose externally, with a tube scarcely 4 times as long as 

 that of the calyx ; the limb quite smooth inside, except just at the edges 

 which are tomentose. Fruit smooth, often H inch long, narrower at 

 the base than the apex, smooth, slightly ribbed^ I have seen 2 certain 

 specimens of this in Mr. Lambert's herbarium, and 6 in that of Dr. 

 Thomson. In the latter collection there also exists a branch of a plant 

 very much resembling this, but having the divaricating inflorescence and 

 tomentose leaves of C. pubescens. I am unable to determine whether it 

 is a variety, a species, or a hybrid production. It is what was described 

 in Mr. Lambert's illustration as the true C.magnifolia of the Fl.Peruv.; 

 but it agrees neither with the figure nor description given in that work, 

 nor with the mass of specimens so named, in the unarranged part of 

 Mr. Lambert's herbarium. What is called C.caduciflora in Lambert's illus- 

 trations is the true C. magnifolia, and is quite different from what M. Bon- 

 pland intended by the former name. According to Ruiz this is one of 

 the species known under the name of Cascarillo de Flor de Azahar, and 

 not met with in commerce, except in the form of extract, which has 

 been found of excellent quality. It derives its name from the resem- 

 blance between the smell of its flowers and those of the Orange, and 

 is one of those discovered in the kingdom of Santa Fe by Mutis. 

 R. and P. The same authors say it is the C. oblongifolia of 

 Mutis ; it is entirely different from the plant called by that name by 

 Mr. Lambert. Ruiz in his MSS. describes the bark as being of indif- 

 ferent quality, of little value in the market ; he says it is the Qui?ia roxa 

 of Santa Fe ; and consequently the red bark of Carthagena, from which 

 port it is shipped for Europe. This has been questioned by Mr. 

 Lambert, but proved to be true, by Bergen, who found it to be the bad 

 bark known in commerce under the name of Quinquina nova. The 

 source of the valuable Red bark of Lima, or Quina colorada is at present 

 unknown. 



Po'ppig found near Cuchero a Corteza de Azahar which he refers to 

 this species, and which he describes thus : "A very stately tree, with 

 unusually large white flowers, diffusing a most delightful scent, like that 

 of orange blossoms. To this bark is never applied the name of Casca- 

 rilla, that is, Fever Bark, in its strict sense, as the ignorant observer 

 does not consider the Azahar to be a Cinchona. It is like, except the 

 stem, a young oak, with bark 4 or 5 lines thick, and woody ; which, for 

 the latter reason, does not roll itself into tubes, possesses little astrin- 

 gency, and is never gathered for sale : still it is said to be applied to 

 officinal uses occasionally in Europe." He adds that it has been 

 chiefly employed in the adulteration of the superior sorts of bark 

 (a very common practice). It however bore too much resemblance 

 to Oak-bark, and was so heavy and easily distinguishable by its 

 very sharp and disagreeably bitter flavour from the fine aromatic taste 

 of the genuine kind, that the imposition could not prevail to a very 

 great extent.
