MONOGRAPHS FOR AN AMATEUR GARDENER'S LIBRARY. 369 
The dissected portions, and especially the seed heads, are most 
admirable work. 
The text is the result of much careful research and a knowledge 
of the living plants, and treats the Clematis purely from a botanical 
and classificatory point of view. 
Mr. Robinson, on the contrary, has given us the horticultural 
side in his beautiful little book, " The Virgin's Bower : Clematis, 
climbing kinds and their culture at Gravetye Manor " (London, 
1912). As with all his books, it is a pleasure only to touch the fine 
paper before enjoying the clear print. Three beautiful reproductions 
of photographs make one long for more. The kinds dealt with are 
arranged more or less in alphabetical order of their specific names. 
Some rather weird English names are provided, as, for instance, the 
Hairbell Virgin's Bower for Clematis campaniflora, where Bell-flowered 
would have been a translation of the Latin ; and I prefer Nicholson's 
translation of Vine Bower for Viticella to the pre-Linnasan sentence, 
Virgin's Bower of the South of Europe. 
The book is a pleasant record of the successes the Clematis family 
have achieved at Gravetye. 
The year 1916 brought two important works on Japanese Cherries. 
One is E. H. Wilson's " The Cherries of Japan " (Publications of the 
Arnold Arboretum, No. 7). It is the result of special investigations 
carried out during the Arnold Arboretum Expedition to Japan in 
1914, and deals with ten species, three of which produce most of the 
large-flowered forms of our gardens. Cerasus pendula, the well-known 
weeping Cherry, and the winter-flowering tree known as Miqueliana 
and micvolepis are stated to be varieties of Primus subhirtella. The 
eight half-tone reproductions of photographs of specimen trees show 
what grand subjects for our gardens these would be could we only 
obtain them on their own roots. 
The second book is vol. xxxiv. art. i. of Journal of the College 
of Science, Imperial University of Tokyo, " Japanische Bergkirschen, 
ihre Wildformen und Kulturrassen," by M. Miyoshi, published in 
Tokyo. The text is in German, and to me its charm and value lie 
in the twenty-one plates at the end, four of which are photographic 
representations of fine specimen trees, one an outline drawing of 
Prunus mutabilis, and the others coloured figures of a great number 
of varieties, chiefly of P. mutabilis and P. serrulaia. Wilson has 
lately written a supplement to his work, altering some of the nomen- 
clature, as Miyoshi's work just antedated his. 
Those who wish to study the Geraniaceae have a wealth of literature 
to guide them. First, there is " Geraniologia," * by Charles Louis 
l'Heritier (Paris, 1787-88), a large folio containing forty-four 
copperplate engravings of Erodiums, Pelargoniums, Geraniums, 
and Monsonias. They are by different artists, but thirty-two are by 
P. J. Redoute, and beautiful examples of his skill. The delicacy 
of his treatment of the finely cut leaves of Erodium supracanum is 
well worth studying. The nearer leaves stand out in a wonderful
