350 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. 



species are fatal to bees. Such is certainly not the case at this station. 

 Here the bees seek them eagerly, but repeated careful observations have 

 failed to discover a single dead bee in the neighborhood of the trees. 

 Few trees can be better recommended for general planting than this the 

 true " red gum." It is one of the species that should be much more 

 freely grown in California. The illustration (plate 48) shows the small 

 seed-pods and drooping stems so characteristic of E. rostrata. 



Eucalyptus corymbosa is a handsome, symmetrical tree of pyramidal 

 habit. Its leaves are narrowly oval, slightly sickle-shaped, a rich dark- 

 green in color, paler beneath, with a conspicuous white midrib. The 

 new leaves are light- yellowish green, with dark-green veining, very 

 attractive. The creamy-white flowers are borne profusely in large, showy, 

 rather loose clusters on the ends of the branches, giving the tree a most 

 ornate appearance when in bloom. The bark is reddish brown, smooth 

 and finely fissured, persistent. As an ornamental tree E. corymbosa ranks 

 with the best of the eucalypts. Its blossoming season has extended here 

 from August through into December, affording good bee forage. Its 

 timber is said to be very hard and very durable for underground pur- 

 poses, but inferior for use in the arts on account of the amount of kino 

 or gum it contains, whence the popular name of "Blood wood." It 

 should, however, make good fuel. 



ACACIAS AND OTHER TREES. 



Acacia cyanophylla, blue-leaved acacia, is a low-growing, spread- 

 ing tree, branching near the ground, its radiating branches and long, 

 drooping branchlets forming a perfect leafy canopy. Its leaves, or 

 more properly phyllodes, are long and narrow and of a bluish cast. The 

 globular flower-heads, borne profusely along the branchlets and twigs, are 

 larger than those of many acacias, and are of a rich orange color. When 

 in bloom, in spring, the tree is very showy. It is admirably adapted for 

 parks and lawns, where it can have room to display its beauties. It is 

 also a useful tree for the home yard. 



Acacia melanoxylon, the blackwood acacia, is a neat, straight-stemmed, 

 symmetrical tree, of regular, pyramidal outline. Foliage very dense, 

 dull green. Flowers pale yellow, in the usual small globular heads. A 

 desirable tree for sidewalk and roadside planting where compact growth 

 and formal effect are desired. The timber is highly valued for many 

 purposes. It is hard, finely grained, and takes a good polish. Even in 

 the young state it makes excellent firewood, about equal to live oak. 



Casuarina stricta. An erect, branching tree, with the typical slim, 

 jointed, horsetail-ash-like branchlets in lieu of foliage. In this species 

 the branchlets are short and rigid, resembling pine needles, and are 

 arranged in tufts. The bark is smooth, dark brown. This is a unique 

 tree for avenue planting, and for producing certain ornamental effects in 

 grouping. 



Angophora lanceolata. The Angophoras belong to the same order as 

 the eucalypts and are very similar trees, differing only in minor botanical 

 characteristics. A. lanceolata yields a strong, heavy timber. It has dark 

 green, sickle-shaped leaves, and large white flowers produced in heavy 

 trusses on the ends of the branches in summer, when the top of the 

 tree is one immense cluster of blossoms. The bark is smooth, bronze- 

 colored, and deciduous.
