246 CALIFORNIA GARDEN FLOWERS 



symmetrical crown and comes into full foliage in the middle of Feb- 

 ruary, two months earlier than the cork elm. 



Eucalyptus. The eucalyptus species of which scores have been 

 introduced from Australia do much to make the California landscape 

 surprising to Eastern and European eyes. Besides the species largely 

 planted for fuel, timber and shade such as the blue gum, red gum, 

 grey gum, etc., as offered in all California nursery catalogues, there 

 are other species which are superior for floral effects and therefore 

 nearer to our present purposes. A few will be cited: 



Eucalyptus polyanthema. Fine tree of full habit, well-branched, 

 with heavy foliage, leaves ovate to rounded in shape, gray-green to 

 soft blue-gray in color. Flowers small, white, in close clusters on 

 ends of branchlets, much resembling gigantic heads of mignonette. 

 Bark roughish, brown, persistent; withstands considerable frost. 



E. diversicolor. The "Karri." Straight, well-branched, symmetrical 

 tree. Leaves ovate-lanceolate, pointed, dark-green, glossy. Flowers 

 white, in heavy clusters; April, May, June, and again in November. 

 Bark smooth, grey-brown, persistent for some years. Profuse bloomer; 

 useful for bees. Good shade tree; yields valuable timber. Growth 

 rapid. 



E. cornuta var. Lehmannii. Displays tendency to divide into 

 several stems at or near ground, making a spreading tree. Leaves 

 small, oblong, thick in texture, dull-green. Flower buds very large; 

 resembling close clusters of horns; flowers in large, globular heads of 

 apple-green filaments; fruit in large, close, spiny clusters; all very 

 remarkable. Blooms July, August, September. Growth (time and 

 conditions as above) height 24 feet, spread of branches 30 feet. 

 Valuable as an ornamental and as a botanical curiosity. 



E. citriodora. Rather slender, straight-stemmed tree, with long, 

 slender, drooping branchlets, and long, narrow, sickle-shaped, bright 

 green leaves. Flowers creamy-white. Leaves exquisitely lemon- 

 scented, retaining the perfume when dried; beautiful and very desirable 

 ornamental. 



E. robusta. Handsome, symmetrically branching tree. Leaves 

 large, ovate-lanceolate, pointed, dark green, glossy, leathery. Flowers 

 large, white. Free bloomer, valuable for bees. Fine avenue tree. 



E. calophylla. Well-formed tree of regular, symmetrical outline, 

 and rather pyramidal form. Leaves ovate to ovate-lanceolate, pointed, dark- 

 green, glossy. Flowers large, white, in large clusters, very con- 

 spicuous ; seed capsules large, urn-shaped, remarkable. Bark cinnamon 

 colored, persistent. Fine ornamental and shade tree. 



E. leucoxylon var. rosea. Elegant, upright tree, with drooping 

 branches, and light, glauceous blue foliage. Leaves medium-sized, 

 lanceolate. Flowers pink, in loose clusters along the drooping
