Macadamia ternifolia, F. v. Mueller. (Helicia ternifolia, F.M.) 



The Nut-tree of sub-tropical East Australia, attaining a height of 

 60 feet ; hardy, as far south as Melbourne ; in forest-valleys likely 

 of fair celerity of growth. In favourable localities it bears fruit in 

 seven years. The nuts have the taste of hazels. 



Maclura aurantiaca, Nuttall.* 



The Osage Orange, or North American Bow Wood, or Yellow 

 Wood. Texas, Arkansas, Louisiana. This thorny deciduous shrub 

 or tree can be well trained into hedges. It is unisexual, and will 

 in favourable localities on rich river-banks attain a height of 60 

 feet, with a stem 2 to 3 feet thick, thus becoming available as a 

 timber tree. It resists severe frosts. The saplings furnish stakes 

 for vines, which are very lasting. The wood serves well for bows, 

 buggy-shafts, carriage-poles, and similar articles. Not readily sub- 

 ject to blight or attacks of insects. It produces from the root a 

 yellow dye. Mrs. Timbrell, at the surmise of the author, has 

 shown that the foliage is as good a food for silkworms as that of 

 the white mulberry, and the silk produced in no way inferior to 

 ordinary silk. M. tinctoria (D. Don), which furnishes the Fustic 

 wood of Central and South America. 



Maclura excelsa, Planchon. 



West Africa, on mountains, up to 3,000 feet elevation. Height of 

 tree to 150 feet. The wood is remarkably durable and tough, 

 beautifully dark brown and veined. Birds feed on the fruit. 



Maclura Mora, Grisebach. 



North Argentina. A high tree. Wood greatly esteemed for its 

 density and toughness ; fruit edible (Dr. Lorentz). 



Magnolia hypoleuca, Siebold. 



Japan. A stately tree, with very large and whorled leaves. 

 Trunk 1 foot in diameter. Wood remarkably flexile ; used for 

 many kinds of utensils. Worthy of introduction as a magnificent 

 garden object (Christy). 



Magnolia macrophylla, Michaux. 



Eastern States of North America. Although not cultivated for 

 any special purposes of the arts or of technics, yet this tree is 

 admitted here into this list as one of the grandest of its kind, as 

 well in foliage as flowers. It attains a height of 40 feet ; its leaves 

 are from 1 to 3 \ feet long, while its flowers attain a diameter of fully 1 

 foot. M. grandiflora, L., attains on the Mississippi a height of 80 

 feet. M. acuminata and M. Fraseri, Walter, are also large trees
