Introduction 



fully as possible, whilst attention is directed to 

 other species, many of which are but little known. 

 The descriptions of the varieties of Ilex Aquifolium, 

 as far as possible, are those of the late Mr Thomas 

 Moore, which appeared at irregular intervals in 

 the Gardener's Chronicle during the years 1874, 

 '75 and '76, the editor of that journal kindly 

 allowing use to be made both of the descriptions 

 and accompanying illustrations. A departure 

 has been made from the usually accepted state- 

 ment that "all the garden Hollies are forms of I. 

 Aquifolium," and for various reasons it has been 

 thought desirable to place some of the varieties 

 under the Canary Island species I. platyphylla, 

 whilst others are referred to as hybrids. Many 

 of the leaf illustrations will be recognised by all 

 who know Moore's Monograph ; there are, how- 

 ever, numerous new ones, together with a selection 

 of photographs of isolated plants and groups, all 

 of which are the work of Mr E. J. Wallis. 



In addition to the Gardener s Chronicle I am 

 indebted to the following works, among others, 

 for information and extracts : Johnston's Botany 

 of the Eastern Borders ; Selby's British Forest 

 Trees; Browne's Sylva of N. America ; Evelyn's 

 Sylva; Miller's Dictionary of Plants; Sargent's 

 Forest Flora of Japan ; Garden and Forest ;
