variety that will be more freely planted when its merits are known. Double and 

 single almonds and peaches (Amygdalus), in variety, are among the first flowering trees 

 of the year, being usually laden with blossom in February and March. They are 

 much grown around London, and require sunny positions for ripening the wood and 

 the formation of blossom buds. The snowy mespilus (Amelanchier canadensis, or 

 JBotryapium) attains a height of 20 feet, 

 and is covered as with a snowy mantle 

 in the spring. It is also known as 

 Pyrus Botryapium. 



Catalpa bignonioides is a good 

 lawn tree, growing upwards of 20 

 feet high, and is remarkable for its 

 bold foliage and handsome panicles of 

 flowers. Double cherries (Cerasus 

 vulgaris fi. pi.) 20 to 30 feet, white 

 or rose coloured, are highly attractive, 

 as is the Judas tree (Cercis siliquas- 

 trum) when laden with its pea-shaped 

 purplish flowers in a setting of yellow- 

 ish green foliage. Cladastris tinctoria, 

 synonym, Virgilia lutea, produces 

 racemes of white flowers freely and 

 can be grown almost anywhere. 

 Double, white, pink, and scarlet haw- 

 thorns (Cratasgus oxycantha) have been 

 previously mentioned and are indis- 

 pensable. The flowering ash (Fraxinus 

 ornus) attains a height of 20 to 30 feet, 



and in May and June is sufficiently attractive to entitle it to a place in pleasure 

 grounds. 



The Snowdrop tree (Halesia tetraptera) (Fig. G6) and the charming Styrax 

 japonica (Fig, 67), which produce multitudes of snowdrop-like flowers in the spring, 

 should not be omitted from ehoice collections ; height 15 to 20 feet. Koelreuteria 

 paniculata, 10 to 15 feet, produces charming panicles of yellow flowers in June and
