Naturalisation in Extra-Tropical Countries. 69 



Baccharis pilularis, De .Candolle. 



California and Oregon. This evergreen bush can be grown for 

 hedges, used also for garlands, wrappers or flower-bouquets and 

 other decorative purposes, as cut branches do not wither for a con- 

 siderable time. It attains a height of 15 feet [Professor Bolander], 

 and could readily be naturalised along sandy sea-shores. 



Backhousia citriodora, F. v. Mueller. 



Southern Queensland. Though only a small tree, it is well worth 

 cultivating for the fragrance of its lemon-scented foliage, from which 

 also a culinary and cosmetic oil can be cheaply distilled. Mr. T. 

 Christy compares the oil to that from Lippia citriodora, and recom- 

 mends Mons. Broquet's apparatus for this and similar distillations. 



Bactris Grasipses, Humboldt. (Guilielma speciosa, Martius.) 



The " Peach-Palm " of the Amazon-River, ascending to the warm 

 temperate regions of the Andes. Stems clustered, attaining a height 

 of 40 feet. The fruit grows in large bunches ; Dr. Spruce describes 

 it as possessing a thick, firm, and mealy pericarp, and when cooked to 

 have a flavour between that of the potato and the chestnut, but 

 superior to either. 



Bacularia Arfakiana, Beccari. 



In Araucaria-forests of New Guinea up to 6,000 feet. A reed-like 

 palm, evidently desirable for decorative purposes. 



Bacularia monostachya, F. v. Mueller. (Areca monostachya, Martius.) 



Eastern Australia, extending to extra-tropical latitudes. One of 

 the best among small palms for table decoration. The stems sought 

 for walking-sticks. 



Baloghia lucida, Endlicher. (Codiceum lucidum, J. Mueller.) 



East- Australia. A middle-sized tree. The sap from the wounded 

 trunk forms, without any admixture, a beautiful red indelible pigment. 

 The wood is adapted for turnery. 



Balsamodendrum Mukul, Hooker. 



Scinde and Beluchistan. Yields the Bdellium-resin. 



Balsamodendrum Myrrha, Nees. (Commiphora Myrrha, Engler.) 



Deserts of Arabia. This tree yields the commercial " Myrrh," but 

 perhaps some other species may produce the same substance. This 

 drug is now used chiefly in dentistry only, though renowned since 

 Hippocrates' time. The oldest genus-name is Commiphora.
