sent to that garden by Wallich. Others exist at the Jardin d'Acclimata- 

 tion in Paris, and two large ones occur in Kew Gardens, one of which 

 latter, which produced male flowers, was figured by Sir J. Hooker in 

 the " Bjtanical Magazine," plate 7128, under the name of T. khasianus. 

 This species is quite distinct from, yet closely allied to, the other two 

 species. It is distinguished by having its leaves regularly divided into 

 segments half-way along the limb ; they are deciduous as the trees get 

 old, so that a large part of the trunk is bare ; the fruits are olive-shaped, 

 resembling that of small species of Plwenia. Figures of the fruit and 

 seed are given. The endocarp is formed of curious colonies of sclerotic 

 cells. A magnified portion of a section of the pericarp is given. Finally, 

 a brief distinguishing description of each of the three species of Trachy* 

 carpus is afforded.— TP 7 . C. W. 



Two-winged Flies, Affecting Farm, Garden, Stock, and 

 Household. By F. L. Washburn (U.S.A. Exp, Stn. Minnesota, 

 UthAnn. Hep. pp. 19-164; 2 plates, 159 figs.; 1906),— An excellent 

 and well-illustrated account of the Diptera of economic importance in 

 Minnesota. Appropriate methods of dealing with the pests are mentioned 

 in all cases where such are called for. — F. J. C, 



Valeriana pyrenaica, Linn. By S. Mottet (Lc Jardin, vol. xxi. 

 No. 485, p. 132 ; with fig. ; May 5, 1907). — The most remarkable and 

 decorative of all the valerians, it has be3n too much neglected ; grows 

 about 4 feet high, with handsome leaves and deep rose-coloured flowers, 

 Lasts well in water. — F, A. W. 



Verbascums, The. By E. H. Jenkins (Garden, No. 1814, p. 90, 



fig. ; August 25, 1906). — The Verbascums, or mulleins, are in their way 

 among the more showy of garden plants, and as such deserve attention 

 at the hands of th3 gardener. To say that this somewhat extensive genus 

 is an important one would be perhaps ascribing praise to it not wholly 

 merited. There are, however, certain species that demand more than 

 ordinary attention by reason of their boldness when well grown, and their 

 alaptability for forming groups of an attractive or even an imposing 

 character. Regarded generally these plants are better suited to woodland 

 gardening or to those othsr parts of the garden where bold effects 

 or vistas may be used with advantage. The large shrubbery border, 

 for example, frequently affords an excellent opening for such plants as 

 these, and if kept away from the radius of hungry tree rcots and their 

 requirements liberally catered for in other ways, a scene of great beauty 

 and attractiveness will result.— E. T. C. 



Veronica Hulkeana. By G. T. Grignan (Bev. Hort. January 16, 

 1900, pp. 40-41 ; coloured plate and woodcuts).— The coloured plate 

 depicts two spikes of flowers of a delicate lilac tint, and much resembling 

 that of the lilac, though less dense. The woodcut shows a handsome, 

 compact, and very floriferous shrub, which is described as very hardy 

 and of easy cultivation* The flowers last long and appear in
