pink blossoms, and their branches cross and interlace, so that the 

 colors mingle in the centre. There can be no prettier deciduous 

 gateway arch than may be made by planting a white- flowering 

 hawthorn on one side, and some of the pink or scarlet varieties 

 on the other, for the purpose of weaving their branches together 

 overhead, and then clipping to perfect the arch, but not so closely 

 on the outside as to mar the graceful freedom of outline that is one 

 of the pleasing features of the hawthorn. Fig. 37, on page 108, 

 illustrates the mode of treatment here suggested. 



The following are a few of the numerous varieties of the haw- 

 thorn : 



The C. oxycatitha pcndula, a charming little pendulous branched 

 tree. Flowers white. 



The C. 0. rosea has rose-colored flowers in great abundance. 

 May. 



The C. 0. punicca has dark-red flowers in May, brilliant, like 

 clusters of verbenas. 



The C. 0. pimkea flore plena has double flowers, less brightly 

 colored. 



The C. 0. muitipkx has double white flowers, which die off a 

 beautiful pink. They are borne in great profusion, and last a long 

 time. It has an unusually dark glossy leaf, of 

 '''^- '+'> the form shown in Fig. 149, and thrives in par- 



tial shade. One of the best. 



The C. 0. lucida is a variety distinguished by 

 its vigorous habit and the unusual thickness and 

 glossiness of its leaves. Flowers white. There 

 are varieties with variegated leaves, but they are 

 not of healthy growth, and therefore not worth planting. 



The C 0. stricta is an upright-growing variet}^, almost as fas- 

 tigiate as the Lombardy poplar, and forms a pretty contrast to 

 some of the flat-headed cockspur thorns. All these varieties may 

 be grafted on any of our wild thorns, and they sometimes succeed 

 on mountain ash, pear, and quince stocks. 



The Scarlet-fruited 7^horn. Cratagus coccinea. — Under 

 this botanical head are grouped many of those varieties or species
