The eighteenth of April is termed Ulmifrondes in the south of England, 

 for then the tree is generally in full foliage. In August and September, when 

 other trees are changing hue, the English elm retains its sombre green foliage, 

 and it is not until after all its neighbors have shed their leaves, that its leaves 

 begin to fade and fall. 



When planted in California the English elm makes an erect, rapid-growing 

 tree, which is remarkably free from the insect pests so common to the American 

 elm. It stands drought well, and because of this quality as well as its long 

 life, neatness and symmetry, is an excellent tree for street and highway- 

 planting. Its chief objections are the suckers which spring in great abundance 

 around the base of the trunk. Browning refers to them as "the brush-wood 

 sheaf round the elm tree bole." 



HUNTINGTON ELM 



The Huntington elm ( Ulmus glabra vegeta) is a hybrid elm of erect habit 

 and rapid, vigorous growth. The large green leaves make a dense foliage which is 

 very attractive. This elm is excellent for street and highway planting because 

 of its resistance to drought and insect enemies. 



EMPRESS TREE 



The Empress tree (Paulownia imperialis) takes its generic name after 

 Anna Paulownia, a Russian princess. It is a native of China and greatly re- 

 sembles the catalpa, the chief difference being in the shape of the pods. It 

 reaches a height of about forty feet and has stout spreading branches which 

 form a round head. The heart shaped leaves are large and tropical looking. 

 The lavender flowers, which resemble those of the foxglove, appear in large 

 terminal panicles followed by pods that remain on the tree during the winter. 

 This tree is adopted for semitropical effects and makes a good growth on 

 fertile soil. It is very subject to sunburn, however, and should be planted 

 where it will be well sheltered. 



EUCALYPTUS 



The genus Eucalpytus, which is native to Australia and the Malayan 

 region, embraces about 300 species, one hundred or more of which have been 

 introduced into California. The name is derived from the Greek words eu, 

 meaning well, and kalypto, to cover as with a lid. The last term has reference
