are given on the authority of Rosenthal's valuable work. The

 repandum, L., and H. suaveolens, Scop. 



Hydrangea Thunbergi, Siebold. 



Japan. The leaves of this shrub give a peculiar Tea, called there 

 the "Tea of Heaven." 



Hydrastis Canadensis, Linne. 



North America. The Yellow Poccoon. Perennial herb, utilised 

 in medicine. The root contains two alkaloids, berberin and 

 hydrastin. The root tinges briliantly yellow, admitting of its 

 use along with indigo for rich green colours. 



Hymensea Courbaril, Linne. 



Tropical and Southern sub-tropical America. A tree of colossal 

 size and remarkable longevity. Timber hard, extremely ponder- 

 ous, close-grained, used for select wheel-work, treenails, beams and 

 planks in various machinery. Courbaril- wood exceeds in elasticity the 

 the best British Oak-wood four times and in resistance to fracture nearly 

 three times (Lapparents). A fragrant amber-like resin, known as 

 West India Copal, exudes from the stem. The Mexican trade 

 name of the resin is Coapinole. The beans of the pod are lodged 

 in a mealy pulp of honey-like taste, which can be used for food. 

 The possibility of the adaptability of this: remarkable tree to the 

 warmer temperate zone needs to be ascertained.
