the authority of Rosenthal's valuable work. The Rev. M. J. 

 Berkeley, Dr. Morren and Dr. Goeppert add HydDum repaudum 

 (Linne) and H. suaveolens (Scopoli). 



Hydrangea Thunbergi, Siebold. 



Japan. The leaves of this shrub give a peculiar tea, called the 

 " Tea of Heaven." 



Hydrastis Canadensis, Linne". 



The Yellow Puccoon or Golden Seal. Eastern North- America. 

 A perennial herb, utilized in medicine. The root contains two 

 alkaloids, berberin and hydrastin. The root-dye is of a brilliant 

 yellow, admitting of its use with indigo for rich green colors. 



Hymeneea Courbaril, Linne". 



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

 size and remarkable longevity. Timber hard, extremely heavy, close- 

 grained, used for select wheel-work, treenails, beams and planks, also 

 in various machinery. Courbaril-wood exceeds the British oak four 

 times in elasticity and nearly three' times in resistance to fracture 

 (Lapparents). A fragrant amber-like resin, known as West-Indian 

 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 chance of the 

 adaptability of this remarkable tree to the warmer temperate zone 

 needs to be ascertained. This is one of the Algaroba- trees. 



Hymenanthera Banksii, F. v. Mueller. 



South-Eastern Australia, New Zealand, Norfolk-Island. A tall 

 spiny shrub, well adapted for close hedges, where rapid growth is not 

 required. It stands clipping well. Flowers profusely fragrant, hence 

 this plant is among those best to be chosen for maintaining succes- 

 sively a strong fragrance in gardens during the whole year in serene 

 climes.
