260 Select Plants for Industrial Culture and 



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

 The Rev. M. J. Berkeley, Dr. Morren and Dr. Goeppert add Hydnum 

 suaveolens (Scopoli) and H. repandum (Linne), the latter also 

 indigenous in Tasmania. 



Hydrangea Thunbergl, Siebold. 



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

 " Tea of Heaven " locally. 



Hydrastis Canadensis, Linn4. 



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

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

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

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



Hymeneea Courbaril, Linn. 



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. H. verrucosa (Gaertner) and Trachylobium 

 Petersianum (Klotzsch) yield the best East- African and Madagascar- 

 Copal. 



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 

 successively a strong fragrance in gardens of serene climes. 



Hyoscyamus niger, Linne\ 



The Henbane. Europe, North-Africa, extra-tropical Asia. In 

 Norway indigenous to lat. 63 35'. An important medicinal herb of 

 one or two years' duration. It contains a peculiar alkaloid hyoscya- 

 min. H. albus (Linne) is used in South-Europe as well. Oulmont 

 and Laurent pronounce daturin from various species of Datura as 

 physiologically almost identical with hyoscyamin.
