 ambitious proportions. There are scores of 

 sorts, but the double-flowered forms of our 

 common Hawthorn are more largely planted 

 than any others. The Hawthorn, Crataegus 

 Oxyacantha, is divided into two sub-species, 

 C. monogyna and C. oxyacanthoides and the 

 double-flowered forms belong to the latter. 

 Good ones are flore pleno albo, white ; flore

 in which they are generally at their best. 

 L. vulgare (the common Laburnum) is the 

 earliest tree to flower, and two or three weeks 

 later there comes the Scotch Laburnum, 

 L. alpinum. This has the finer foliage and 

 flowers. A number of hybrids have appeared 

 between the two which show remarkable 

 vigour. Watereri has fine racemes of flowers. 

 Parksii bears flower racemes 12 to 18 inches 

 long, and the same can be said of Latest

 galli splendens, coccinea, mollis, punctata, 

 prunifolia, Carrierei and cordata. Of Cra-

 named praecox, with the common name 

 of Glastonbury Thorn. Some of its flowers 

 open in May, but many of them appear 

 between November and Christmas.

The Laburnums are the best flowering 

 trees in June. In the south they often begin 



and Longest. Laburnum Adamii is a very 

 interesting and curious tree. It occurred as 

 a graft-hybrid after Cytisus purpureus (the 

 Purple-flowered Broom) had been grafted 

 upon a stock of common Laburnum. The 

 tree possesses the peculiarity of bearing 

 purple and golden racemes of flowers and 

 tufts of branches identical in leaf and flower 

 with those of Cytisus purpureus. 



The Judas Tree (Gercis Siliquastrum) 

 blossoms during early June, or sometimes 

 late May in the south. Its reddish flowers 

 appear from old branches and those formed
