Naturalisation in Extra-Tropical Countries. 321 



Cattle like to browse on the foliage. The tree will grow on the 

 coast down to high-water mark, and is one of the few trees that will 

 grow in wet saline ground. The wood is close-grained, useful for 

 cabinetwork [C. Walter]. 



Myoporum Isetmn, Forster. 



New Zealand, where it is called Ngaio by the aborigines, also in 

 the Chatham-Islands. As a shelter-tree it is equal to the Australian 

 M. insulare for the most exposed parts of the coast. It is excellent 

 for shade, and its wood takes a fine polish. It can be raised on the 

 beach from cuttings. Uprooted it will produce new roots, if 

 covered in near the sea. Sheep, cattle and horses browse on the 

 foliage. 



Myrica Californica, Chamisso and Schlechtendal. 



Californian Sweetgale-tree, attaining 40 feet in height and a stem- 

 diameter of 3 feet. The leaves, pervaded by a balsamic resinous- 

 oily principle, are of medicinal value [Dr. Kellogg]. The root-bark 

 of several Myricas is also turned to therapeutic account. 



Myrica cerifera, Linn& 



The Wax-Myrtle or "Bay-Berry." Sandy sea-coast of Eastern 

 North- America. This shrub helps to mind the rolling sand ; it has 

 fragrant leaves ; the fruits are boiled, and the floating wax, which 

 can be converted into candles, is skimmed off, In Patagonia, 

 Argentina and Chili the scrophularinous Mont tea aphylla, Bentham 

 (Oxycladus aphyllus, Miers), yields vegetable wax from its branches 

 [Lorentz]. 



Myrica cordifolia, Linn<. 



South- Africa. This bushy plant arrests the influx of the sea- 

 sand ; it also yields wax from its fruits in remunerative quantity. 

 Mr. A. W. Heywood mentions as South-African sandcoast-plants 

 also : Lotononis gracilis (Bentham), attaining a circumference of 45 

 feet ; Microstephium niveum (Lessing), Othonna cylindrica (De 

 Candolle), Caroxylon Salsola (Thunberg), with long creeping roots. 



Myrica Faya, Dryander and Alton. 



Madeira, Azores and Canary-Islands. A small tree. The 

 drupaceous fruits are used for preserves. 



Myrica quercifolia, Linn. 



South-Africa. This is one of the principal wax-bushes there. 

 Many other species from different parts of the globe are available for 

 trial-culture, but none have as yet been discovered in Australia.
