ADDITIONS AND CORRECTIONS 



After the foregoing pages had been printed space was found to be available for 

 the following additional species. All can be grown successfully somewhere on 

 the mainland of the British Isles or Western Europe. (The Scilly Isles, where 

 apparently almost anything can be grown, are outside the region of this work.) 



No additions have been made to the genus Rhododendron, which, though highly 

 ornamental and met with everywhere, would require a separate volume. Again, 

 large genera, such as Berberis, Crataegus, Primus, Salix, Veronica, and Viburnum, 

 could be added to indefinitely ; the result would, however, be of little interest to 

 those who are not specialists in these genera. Acer and Populus have been dealt 

 with more fully, as they are fast-growing and popular on that account. 



With regard to synonyms, so many are in use that it has been found quite 

 impossible to give more than a few. The Hand-List of Trees and Shrubs cultivated 

 i?i the Royal Botanic Gardens, Kew (Fourth Edition, 5^. 6d.), and the companion, 

 Hand-List of Coniferae (Third Edition, is. 6d.), contain most of the synonyms, but 

 nurserymen often use names which can be found in neither of these publications. 

 The difficulties of nomenclature could be overcome in a comparatively short time 

 if nurserymen and amateur cultivators would take the trouble to acquaint them- 

 selves with the international rules, and discard all illegitimate names. ^ As most 

 of them have failed to do so, however, illegitimate names are often given precedence 

 in this book, though not without reluctance. 



The months of flowering cannot always be relied upon, particularly in species 

 from the southern hemisphere, where the seasons are reversed. In mild seasons 

 such species may flower at any time; and the flowering of native species is often 

 abnormal for the same reason. Where no information under this head has been 

 given the species has either not been known to flower in the British Isles or reliable 

 information has not been forthcoming. 



Any notifications of mistakes or important omissions will be gratefully received 

 by the author, and will be incorporated with suitable acknowledgments in a revised 

 edition if possible.
