of the glucoside " quercetin," the yield being rather over half per cent. 

 The capsules and flowers of T. populnea were already known to yield a 

 yellow dye. As in the case of Hibiscus sabdariffa investigated by the 

 same author (see abstract) profco-catechu-aldehyde had apparently been 

 present in the fresh flowers as a perfume. — W. A. V. 



Conifers, On the Distribution of, in the Several Districts 



of China. By the late Maxwell T. Masters, F.R.S. {Jour. Linn. Soc. 

 Vol. xxxviii. No. 265. pp 198-205 ; 1908).— The total number of Conifers 

 known from China, inclusive of Formosa, amounts to eighty-seven 

 distributed through twenty-three genera. Speaking generally, a marked 

 difference may be noted in the Coniferous floras of Northern, Southern, 

 Central, and Western China respectively. The relationship between the 

 Conifers of the different Chinese provinces to those of surrounding 

 countries is then indicated. The paper contains two tables. Table 1 

 shows the distribution of the genera of Conifers in China and Japan. 

 Table 2 gives a list of all the species of Conifers known to be native of 

 China and shows their distribution in the various districts of the empire 

 and in neighbouring countries. — B. B.

Cotton, Experiments with Egyptian, in 1908 (U.S.A. Dep. Agr., 

 Bur. PI. Ind., Cir, No. 29, April 1909). — An account of experiments in 

 acclimatizing Egyptian Cotton in the Colorado River region. Ifc is shown 

 that imported seed does not entirely flourish in its new quarters, but in 

 time it is hoped that home-grown seed will be produced which shall be 

 absolutely adapted to the new conditions and which will produce fibre of 

 good quality. It is not recommended that the crop should be planted on 

 any large scale at present, and great care is insisted on to exclude seed 

 infected with the disease known as "black arm," which once introduced 

 would kill a rising industry in that district.— M. L. H.
