172 NATURAL BISTORV OF PLANTS. 



owes its perfume to C.flavcns. C. animfus ' of Madagascar has, in 

 th.e dry specimens, the exact odour oillliciiim amsafnm. The leaves of 

 C. Carjjoj)hyllus haA^e, it is said, the odoui- of Cheiranthus ; those of 

 C. fragnms^ menthodorum * and balsamcimi,^ American species, are very 

 aromatic. C. glabellm^j;' from the Antilles, has a perfumed bark, like 

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

 and C. ccltidlfolius^ 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 ti-eatmentof 

 wounds and contusions, as C. nhutiloides,'^ gossypifolim^^^ Ui'ucurana^^ 

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

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

 its furnishing Melambo bark, aromatic, camphorate, analogous 

 to that of Drimgs, Boldu and Atherosperma, stimulant, digestive, 

 febrifuge and strengthening. In certain aromatic species of India, 

 the natiu-e of the juice is modified by the influence of the punctures 

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

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

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

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

 exciting, is considerable in the tropical regions of the world.'"' Others 

 have very variable properties, hardly explicable, and there are 

 many Euphorbiacece of other genera the same. Thus, Euphorbia 

 Schimperiana ^^ and cerebrina^"^ are mentioned as dyes ; and in their 

 native country, Abyssinia, they value Croton macrudachyus '* as
