NATURAL HISTORY OF PLANTS. 



owes its perfume to C.fiavens. C. anisafus ^ of Madagascar has, in 

 the dry specimens, the exact odour oilllicium anisatum. The leaves of 

 C. Canjophyllus have, it is said, the odour of Cheiranthus ; those of 

 C. frafjrans^ mcnthodorum * and halsamcum,^ American species, are very 

 aromatic. C. fflabelhis,'' from the Antilles, has a perfumed bark, like 

 C. Eluteria, for which it is said to be substituted. C. vulnerarius '' 

 and C. celtidifoliiis^ are also stimulant and vulnerary. The last 

 especially owes its properties to a reddish juice found in a good 

 number of American species, sometimes employed for the treatment of 

 wounds and contusions, as C. ahutiloides^ gos^upifoUus^^lIrucurana^^ 

 and Draco ^'^ aromatic plants, whose concreted juice is compared for 

 its properties to Dragon's-blood. O. Malamho ^^ owes its name to 

 its furnishing Melambo bark, aromatic, camphorate, analogous 

 to that of Dr'mujs^ Boklu and Athcrosperma, stimulant, digestive, 

 febrifuge and strengthening. In certain aromatic species of India, 

 the nature of the juice is modified by the influence of the pimctures 

 of insects. It is believed that it is owing to the action of Coccus 

 Lacca on its branches that the C. uromaticiim ^^ of India yields the 

 gum-lac, employed in medicine and the arts. The number of species 

 of Croion with odoriferous juice, balsamic or resinous, tonic or 

 exciting, is considerable in the troj^ical regions of the world. ^' Others 

 have very variable properties, hardly explicable, and there are 

 many Eiqihorbiacecv of other genera the same. Thus, Euphovhiu 

 Schimperiana ^" and cerehrina,^'' are mentioned as dyes ; and in then- 

 native country, Abyssinia, they value Crohn macrostachijus ^® as
