Naturalisation in Extra-Tropical Countries. 31 



Aleurites cordata, R. Brown. 



From Japan to Nepal, also in Reunion. This tree deserves culti- 

 vation for its beauty and its durable wood in warm humid districts. 

 The oil of the seeds serves as a varnish. Perhaps in localities quite 

 free from frost it would be of sufficiently quick growth extra-tropi- 

 cally. 



Aleurites triloba, R. and G. Forster. 



The " Candlenut-tree," a native of some of the tropical regions of 

 both hemispheres ; it furnishes a valuable dye from its fruits and 

 copious oil from its seeds, the yield being about one-third. I found 

 the tree barely able to endure the winters of Melbourne, but towards 

 Port Curtis, somewhat outside the tropics, heavy returns of seeds 

 are annually obtained [J. S. Edgar]. 



Alibertia edulis, A. Richard. 



Guiana and Brazil, southwards to extra-tropic latitudes, widely 

 dispersed through the drier regions. The fruit of this shrub is 

 edible and known as " Marmeladinha." A. Melloana (J. Hooker) of 

 Southern Brazil seems to serve the same purpose. 



Alkanna tinctoria, Tausch. 



On sandy and calcareous places around and near the Mediterranean 

 Sea, extending to Hungary. Endures a very dry clime. Cultivated 

 in the open air to perfection up to 59 55' North by Professor 

 Schuebeler. This perennial herb yields the " Alkauna-root," used for 

 dyeing oleaginous, waxy and other substances. It might be natura- 

 lised. Can be grown in almost pure coast-sand. 



Allium Ampeloprasum, Linn. 



The British Leek. Middle and Southern Europe, Western Asia, 

 and North-Africa. Called in culture the Summer-Leek, a variety of 

 which is the Pearl-Leek. The specific name arose already from Dios- 

 corides' writings. 



Allium Ascalonicum, Linn. 



The Shallot. South- Western Asia. Specific name already used by 

 Theophrastos and Plinius. Ripens seeds even in Central Australia. 

 [Rev. H. Kempe]. 



Allium Canadense, Kalm. 



Eastern North-America. This Garlic could be cultivated or 

 naturalised on moist meadows for the sake of the tops of its bulbs, 

 which are sought for pickles of superior flavour.
