FLOWERING TREES AND SHRUBS 53 



C. Oxyacantha punicea flore-pleno (Paul's double- 

 scarlet Thorn) is one of, if not the handsomest variety, 

 ■with large, double flowers that are of the richest crimson. 

 Other good flowering kinds include C. Oxyacantha prsecox 

 (Glastonbury Thorn) ; C. Oxyacantha Oliveriana ; C. 

 Oxyacantha punicea, with deep-scarlet flowers ; C. Oxya- 

 cantha rosea, rose-coloured and abundantly-produced 

 flowers ; C. Oxyacantha foliis aureis, with yellow fruit ; 

 C. Oxyacantha laciniata, cut leaves; C. Oxyacantha 

 multiplex, double-white flowers ; C. Oxyacantha foliis 

 argenteis, having silvery-variegated leaves ; C. Oxyacantha 

 pendula, of semi- weeping habit; C. Oxyacantha stricta, 

 with an upright and stiff habit of growth ; C. Oxyacantha 

 Leeana, a good form ; and C. Oxyacantha leucocarpa. 



C. paevifolia. — North America, 1704. This is a 

 miniature Thorn, of slow growth, with leaves about an 

 inch long, and solitary pure white flowers of large size, 

 which open late in the season, and are succeeded by 

 yellowish-green fruit. 



C. Pyracantha. — Fiery Thorn. South Europe, 1629. 

 This is a very distinct species, with lanceolate serrated 

 evergreen leaves, and pinkish or nearly white flowers. The 

 berries of this Thorn are, however, the principal attraction, 

 being orange-scarlet, and produced in dense clusters. C. 

 Pyracantha crenulata and C. Pyracantha Lelandi are 

 worthy varieties of the above, the latter especially being 

 one of the most ornamental-berried shrubs in cultivation. 



C. tanacetifolia. — Tansy-leaved Thorn. Greece, 1789. 

 This is a very late-flowering species, and remarkable for 

 its Tansy-like foliage. It is of unusually free growth 

 in almost any class of soil, and is undoubtedly, in so far 

 at least as neatly divided leaves and wealth of fruit are 

 concerned, one of the most distinct and desirable species 

 of Thorn. The white flowers are produced in May. 



Other good species and varieties that may just be 

 mentioned as being worthy of cultivation are C. apiifolia,
