was originally described about two years ago from material which 
was included in the rich collections made by Dr, A. F. G. Kerr, 
near Chiengmai, Siam. --Seeds were sent to Kew by Dr. Kerr in 
1912, and from these the plant now figured was raised. The species 
is caulescent, with membranous ovate or elliptic-ovate leaves 1-33 
inches long, and a racemose cyme, ultimately 10 or 12 inches long, 
of purple flowers. 
A New Work on Conifers.**—We have received a copy of this 
excellent and profusely illustrated work, recently published under 
the editorship of Count Ernst Silva Tarouca and Dr. Camillo 
Schneider, President and Secretary respectively of the Dendrologi- 
eal Society of Austria-Hungary. There is scarcely a page without 
an illustration, many pages have two, and the attractiveness of the 
volume for the general public is enhanced by twelve reproductions of 
photographs in colour. There are also six folded plates devoted to 
the delineation in black and white of cones, chiefly those of Pinus, 
Abies and Picea, The usefulness of the volume for purposes of 
identification is increased by numerous engravings of leaves, leaf: 
- sections, buds, cone-scales, ete. On the whole it is probably the 
most comprehensively illustrated volume on conifers in existence. 
The pinetum of Mr. G. Allard (K.B., 1913, p. 316) has supplied a 
large number of subjects for illustration, and the Vilmorin collections 
at Verriéres and Les Barres in France, and the Royal Gardens at 
Sans Souci and Dresden, as well as Mr. Hesse’s nursery at Weener, 
have supplied the editors with much foreign material for illustration. 
The unrivalled pinetums in the British Isles possess much finer 
examples than many published in this volume, but for a work in 
erman and inten primarily for Austrian and German use, a 
series of pictures taken in Central Europe is, no doubt, of more 
interest and value than those would be made in our milder insular 
The first part of the work is devoted to a general discussion of 
the family. The editors deal with the landscape value of conifers 
in park and garden ; Mr. E, H. Wilson writes of Chinese conifers ; 
Mr, A. Rehder on North American ones, Cultivation and propa- 
gation are discussed by Mr. Franz Zeman. 
The second part is devoted to an analytical key of the whole
