Variegation, Transmission of, by Grafting. By G. T. Grignan 

 {Rev. Hort. April 16, 1905, pp. 108-4). — Further report on M. Linde- 

 muth's experiments. Abutilon Thompsonii has transmitted its variegation 

 to other members of the Malvaceae, producing Kitaibelia Lindemuthi, 

 Maluastram Lindemuthi, &c, as variegated novelties of merit. There 

 appear to be two kinds of variegation, one constant and transmissible 

 by seed, the other a contagious affection and not transmissible by seed 

 but by graft infection. The last M. Lindemuth considers rare, and so 

 far only determined in Abutilon. — C. T. D. 



Vines, Ring-barking of (Rev. Hort. Jan. 1, 1905, p. 6).— It is 

 recommended by M. Charmeux, of Thomery, that for late-fruiting vines 

 a very narrow ring of bark be cut out at the flowering time just below 

 the bunch. This is claimed to stop the descent of sap, by which operation 

 the fruit benefits.— C. T. D. 



Violet ' Cyclopi.' By S. Mottet (Rev. Hort. Nov. 1, 1905, p. 520 ; 

 2 woodcuts). — A violet of good habit and large blue flowers, distinguished 

 by a set of small central nearly white petals. Distributed by Vilmorin.

Vitis Ampelopsis Henryana. Anon. (Gard. Chron. No. 983, 

 p. 309, fig. 122 ; Oct. 28, 1905).— Was discovered by Dr. Henry in Central 

 China. It is much like the old Virginian creeper, but its colour is 

 " even more gorgeous, and the nerve in the centre of each leaflet is 

 marked by a silvery band. The colour of the young leaves is a brilliant 

 translucent scarlet, passing, as the leaves get older, into a rich carmine, 

 and ultimately into a ruddy bronze with the silvery marking before 

 mentioned. It is, we believe, quite hardy." — G. S. S. 



Wattle, Australian, Cultivation of. By David G. Fairchild 

 (U.S.A. Dep. Agr. Bur. PI. Ind. Bull. 51 ; plates). — A description is given 

 of an Australian wattle plantation in Natal, with a view to the intro- 

 duction of the wattle by American cultivators into Hawaii. 



The bark of the Australian wattle (Acacia mollissima) has long been 

 in use for tanning purposes, and in Natal, where it grows as well as in its 

 native country, its cultivation yields a handsome profit ; the trunks, after 

 being stripped of bark, being valuable as pit props. — M. L. H. 



Wild Rice Seed, Storage and Germination. By J. W. T. Duvel 

 (U.S.A. Dep. Agr. Bull. 90, Feb. 21, 1906; 2 plates).— This bulletin 

 details the distribution of Zizania aquatica, habitat, germination of 

 the seed, directions for storing, and results of storage experiments. As 

 dried seed will germinate but rarely, directions are given for storage 

 without deterioration, packing for transportation, sowing, and general 

 germination tests at temperatures varying from 15° to 30° C. (60° to 

 86° Fahr.), the maximum being about 35° C. (95° Fahr.). Wild rice 

 is of importance as a food for water-fowl, a delicious breakfast food for 

 man, and will grow luxuriantly in warm or cold water. — M. C. C. 



Yantias or Taniers of Porto Rico. By O. W. Barrett (U.S.A. 

 Agr. Exp. Stn. Porto Rico, Bull. 6, April 1905; illustrated).— This 

 interesting pamphlet (the first on the subject) was published to remedy
