the surface of the water in breeding places were of general appliea- 

 tion ; but it is dithcult to imagine how the necessaiy conditions would 

 obtain in some of the Macedonian death-traps. It is probal)le tliat 

 in the attack on the mosquito — an attack which will have to be made 

 from many sides — botany will play a considerable ])art. In addition 

 to such points as the above there is the question of larval food, which 

 is mainly algal; algie can be removed by using very weak copper 

 sulphate solution. Furthermore, larvfe frequently suffer from fungus 

 attack, one or more Saprolegniaceae being concerned ; such fungi are 

 easily cultivated, e. g. on ant eggs. — J. K. 



We note with surprise that The Garden, in its issue for May 1, 

 publishes an advertisement headed " Pyrola," offering to supply "one 

 square foot of sod, containing numbers of this beautiful and interest- 

 ing native, post paid, on receipt of 4s." The address leaves no doubt 

 that the reference is to the rare and beautiful sandhill form of 

 Pyrola rotundifolia, which is already scarce in its localities and 

 which is thus in danger of being exterminated. A somewhat feeble 

 protest is made in the same journal for May 22, but it seems to us 

 little short of scandalous that a paper so widely circulated and so 

 deservedly popular should allow such an advertisement to appear in 

 its columns. 



The Annals of Botany (April) contains contributions on the 

 Vascular System and on the Anatomy of the Cone of Equisetum, by 

 Miss Kate Barratt and Lady Isabel Browne respectively ; on the 

 * Brown-Rot' Diseases of Fruit-trees, with special reference to Monilia 

 cinerea, by H. Wormald ; on Puccinia malvacearum and the Myco- 

 plasm Theory, by M. A. Bailey ; and on Plant Succession and Plant 

 Distribution in South Africa, by Dr. J. W. Bews : Dr. Nellie Carter 

 continues her Studies on the Chloroplasts of Desmids. The papers 

 are fully illustrated. 



A ]^ovELTY in nomenclature is presented by the name Allwoodii, 

 which Messrs. Allwood Brothers, of Wivelsfield, have applied to a 

 " new race of garden plants " : " half Pink and half Carnation, they 

 possess distinctive qualities which must appeal to all lovers of Howers, 

 and with their delightful perfume and compact Pink-like habit of 

 growth; they will undoubtedly find a place in every garden." The 

 name apparently takes generic rank in horticultural circles : we read 

 of Allwoodii Jean, Allwoodii Harold, etc. 



Mr. C. E. Salmon's Ne-w Flora of Surrey is announced for 

 publication to subscribers at thirty shillings net, post free, the excep- 

 tionally high price for a local flora being rendered necessary bv the 

 cost of printing and material. More than half a century has passed 

 since the publication of Brewer's Flora, which in the new work will 

 be brought up to date ; it will be illustrated by photographs and 

 will contain two maps. The book wdll be published by the author, 

 Pilgrims' Wa^^, lleigate. 



The Kew Bulletin (No. 4) contains an elaborate discussion by 

 Dr. Stapf of the claims of Setaria and Chcetochloa, the latter of 

 Avhich has been proposed by Dr. Scribner for retention : the decision 

 is in favour of the former. New Indian plants of various orders are 

 described bv Mr. Dunn, and new Orchids by Mr. liolfc ; there is
