FOR VICTORIAN INDUSTRIAL CULTURE.

(R. and G. Foster), the Candlenut-tree, a native of the 

 tropics of both hemispheres, which furnishes a valuable dye 

 from its fruits, and copious oil from its seeds. I found the 

 tree able to endure the winters of Melbourne. 



Alkanna tinctoria, Tausch. 



On sandy places around the Mediterranean Sea. It yields 

 the Alkanna-root, used for dyeing oleaginous and other 

 substances. It might be naturalised. 



Allium Canadense, Kalm. 



North American Garlic. Could be cultivated or naturalised 

 on moist meadows for the sake of its top bulbs, which are 

 much sought for pickles of superior flavour. 



Allium roseum, Linne. 



Countries on the Mediterranean Sea. This, with Allium 

 Neapolitanum (Cyrillo), one of its companions, yields edible 

 roots, according to Heldreich. 



Allium Schoenoprasum, Linne. 



The Chives. Europe, Northern Asia and North America. 

 Available for salads and condiments. This species of Allium 

 seems not yet so generally adopted in our culinary cultivation 

 as Allium Ascalonicum (the Shallot), A. Cepa (the ordinary 

 Onion), A. fistulosum (the Welsh Onion), A. Porrum (the 

 Leek) or A. sativum (the Garlic). A. Scorodoprasum, or 

 the Sand-Leek of Europe and North Africa, resembles both 

 Garlic and Shallot. A. Ampeloprasum is the British Leek, 

 which extends over Middle and South Europe and West 

 Asia, called in culture the Summer-Leek, a variety of which 

 is the Early Pearl Leek. 



Alnus glutinosa, Gaertner. 



The ordinary Alder. Throughout Europe and extra-tropical 

 Asia, up to seventy feet high ; well adapted for river-banks ; 

 wood soft and light, turning red, furnishing one of the best 

 charcoals for gunpowder ; it is also durable under water, and 

 adapted for turners' and joiners' work. The wood is also 

 well suited for pump-trees and other underground work, as 

 it will harden almost like stone. The tree is valuable for the 

 utilisation of bop[-land. A. incana (Willd.) extends to North 

 America ; it is of smaller size. The bark of several Alders 

 is of great medicinal value, and a decoction will give to cloth 

 saturated with ley an indelible orange colour (Porcher); it 

 contains a peculiar tannic principle. 



Aloe dichotoma, Linne fil. 



Damara and Namaqua-land. This species attains a height of 

 thirty feet and expands occasionally with its branches so far
