74 TREES AND SHRUBS 



are the red, yellow, and orange-coloured varieties of 

 H. Helix arborescens. 



HYMENANTHERA CRASSIFOLIA, from New Zealand, 

 is a dense-growing, stiff-branched, dwarf shrub, 

 chiefly noteworthy for the white berries it bears. 



HYPERICUMS. //. Androscemum and H. datum pro- 

 duce rather handsome clusters of black fruits. 



HIPPOPHAE RHAMNOIDES, the Sea Buckthorn, is one 

 of the most brilliantly coloured of all berry-bearing 

 shrubs. It produces them in marvellous profusion, 

 and they are bright-orange coloured. Birds do not 

 molest the berries, and unless caught by severe frosts 

 (which turn them grey) they lighten the garden 

 wonderfully up to, and sometimes after, the New 

 Year. The necessity of growing both sexes of plants 

 has already been noted, but isolated females may be 

 artificially impregnated by shaking pollen over them 

 when in flower. 



ILEX (Holly). The berries of the Holly are so 

 well known that we need only mention the yellow- 

 berried one (fructu-luleo)j which is not common, but 

 very effective in winter. 



LIGUSTRUM. The Privets are of little consequence 

 as fruit-bearing shrubs, and only L. sinense need be 

 mentioned; it is frequently very striking in early 

 winter, being covered then with great clusters of 

 purple-black, shot-like berries. 



LYCIUM CHINENSE. Nearly all the Box Thorns in 

 this country belong to this species. As for /.. europceum 

 and L. barbarum, the names are very common, but 

 the plants themselves very rare. L. chinense is very
