Clianthus Dampieri, Grafting* of. By Von W. Vorwerk (Gar- 



tenflora, vol. Hx. pt. xxi. pp. 469, 470). — It is advisable to graft 

 Clianthus Dampieri seedlings on seedlings of Colutea arhorescens. Tn 

 February the Colutea is sown in sandy soil, and the young plants 

 pricked out in pots of light soil and grown on with bottom heat. Then 

 the Clianthus is sown. The seedling is cut off close to the ground 

 and the wedge-shaped piece inserted in a slit cut between the cotyle- 

 dons of the seedhng Colutea. The graft is held in place by wrapping 

 with yarn. The plants are placed in a closed frame at 60^ F. and 

 protected from sun and wet for ten days. They are then given air 

 and sun, and may be planted out in the open or placed in a cool house 

 by the end of May.— 5'. E. W. 



Climate: So-called Changes in the Semi-arid West. By 



R. N. Sullivan (U.S.A. Dep. Agr. Year Book, 1908; pp. 6).— An 

 interesting account of the supposed alteration of climate by the decrease 

 of forest lands and increase of cultivation. This idea has long been 

 held, by Gibbon among others, but reference to records dating from 

 1870 show no evidence for its support in Western America. — E. A. Bd. 



Coccideae, Catalogrue of Recently Described. II. By J. G. 



Sanders, M.A. (U.S.A. Dep. Agr., Bur. Efitom., Tech. ser. 16, pt. iii., 

 Dec. 22, 1909). — In this catalogue, the second of the series, are 

 included references to 24 new genera, 195 new species, and 14 new 

 varieties of Coccideae or scale insects, with their habitations and the 

 names of the plants on which they have been found. — V. G.J. 



CoelOgryne (Oestr. Gart. Zeit. vol. v. pt. x. pp. 381-384).— The 

 genus Coelogyne is divided into two sub-genera, Succedaneae and 

 Simultaneae, which are further divided into the series (a) Nudae, 

 (b) Vaginatae, (c) Nudiscapae, (d) Glumacae, (e) Imhricatae. — S. E. W . 



Coflfea : Materials for a Botanico-Agricultural Study of the 



Genus. ByE. deWildeman (Ann. Jard. Bot. Buit. 3rd supp. 1st part, 

 1910, pp. 345-384). — This paper contains a very detailed enumeration 

 of the species, varieties, forms and hybrids belonging to the genus 

 Cojfea. The work is prefaced by an interesthig discussion of the diffi- 

 culties which stand in the way of obtaining a really satisfactory classifi- 

 cation of the coffees, and previous attempts in this direction are re- 

 viewed at some length. — R. B.
