226 Select Plants for Industrial Culture and 



Hardwickia binata, Koxburgh. 



India, up to elevations of nearly 4,000 feet. Maximum-height of 

 tree, 120 feet. Wood from red-brown to nearly black, close-grained, 

 exceedingly hard, heavy and durable ; valued for under-ground 

 work. The bark furnishes easily a valuable material for cordage. 

 The tree can readily be pollarded for cattle-fodder [Brandis] . 



Harpullia Killii, F. v. Mueller. 



The Tulip-Wood of Queensland. One of the most important of 

 the numerous kinds of trees indigenous there for select cabinet- 

 work. H. pendula (Planchon) is equally valuable. 



Hedeoma pulegioides, Fersoon. 



The Penny-royal of Eastern North- America. An annual herb 

 of aromatic taste, employed in medicine. The volatile oil is also 

 in use. 



Hedera Helix, Fuchs. 



The Ivy. Europe, Northern Africa, Western Asia as far as the 

 Himalayas. Not to be omitted here, as it quickly forms evergreen 

 walls over all kinds of fences and on sides of buildings without in- 

 juring any sound masonry ; it is also a bee-plant. Individual plants 

 will live through several centuries. The variety with yellow- 

 marked leaves is singularly ornamental. Resists the smoky air of 

 cities [London]. Hederic acid is of medicinal value. A decoction 

 of the leaves dyes hair black. 



Hedysarum coronarium, Linne.* 



The Soola-Clover. Southern Europe, Northern Africa. One of 

 the best of perennial fodder-herbs, yielding a bulky return. It is 

 also recommendable as quite a handsome garden-plant and as a honey- 

 plant. 



Heleocharis sphacelata, E. Brown. 



Australia, New Zealand and South-Sea Islands. This rush is 

 well deserving to be transferred to any swamps in warmer climes 

 on account of its nutritious and palatable tubers. 



Heleocharis tuberosa, Koemer and Schultes. 



China, where it is called Matai or Petsi. This rush can be sub- 

 jected to regular cultivation in ponds for the sake of its edible 

 wholesome tubers. For a full account see Paillieux et Bois in 

 Bullet, de la Soc. d'Acclimat. 1888 p. 1030-1035. H. plantaginea 

 (Brown) and H. fistulosa (Schultes) of tropical Asia and Madagascar 

 are allied plants.
