26 SHOUT NOTES 



dans les Flores soiit insuffisants pour separer les deux especes. Dans 

 men etude monographique sur le genre Lepidium (1906), p. 76, les 

 especes sont caracterisees, dans la clef analytique, comme suit: L. cam- 

 pestre : Planta annua vel biennis. Silicula dense papilloso-squamuloso- 

 aspera. i^tjdi pars libera cum maximum \ mm. longa. Caulis 

 pleruiiique solitarius e centro rosulaj basilaris, strictus .... L. hetcro- 

 phijlliini : Planta perennis, basi rudimentis foliorum Fibrosis vestitis. 

 kSilicula non vel leviter tantum squamnloso-papillosa. Stvli pars 

 libera plerumque cum minimum 1 mm. longa. Caules complures ex 

 axillis foliorum basilarium enati. L. liett^roplti/Uuni se distingue en 

 outre du L. campestre par les Heurs un peu plus grandes, a petales 

 a limbe suborbiculaire-obove (obove-cuneifonne ehez L. c(iiiipfstre). 

 Je suis volontiers pret a determiner des echantillons qui pourraient 

 faire des difficultes a vos abonnes. — A. Thelll'xg, Zurich.

In this verv handsome volume — technically a (juarto but corivs- 



ponding rather with vhe popular idea of a folio — Mr. J. G. Millais 



has produced a worthy companion to his great work on The Manunals 



of Great Britain. An enthusiastic grower of Rhododendrons in a 



county which is famous for these beautiful plants, Mr. Millais lias 



devoted eleven years to their study from a practical point of view in 



his o-arden at Compton's Brow, near Horsham, under the tutelage of 



his friend and neighbour. Sir Edward Loder, of whose wonderful 



woodland garden he gives a detailed account. 



Considering the popularity which Rhododendrons have attained 

 and the number of species which have of recent years been introduced 

 into cultivation, it is certainly remarkable that no illustrated work 

 has been devoted to them since the publication of Sir Joseph Hooker's 

 beautiful volume on The Rhododendrons of the Sikkini Himalaya in 

 18-19. Botanists will perhaps regret that Mr. Millais's artists have 

 not been instructed to employ their talents on work of more strictly 

 scientilic value than this volume affords ; but its primary object is 

 horticultural rather than botanical ; its aim, the author tells us. is 

 "to suiiply a book that may be of practical use to the gardener who 

 only possesses a love of beautiful plants and does not trouble himself 

 witli too much science, and also to consolidate in one volume all that 

 is known of the genus Rhododendron.''^ The plates, whether coloured 

 or plain, are of a high order of merit. The " colour groups " by 

 Miss Beatrice Parsons and the drawings of individual plants, mostly 

 of new hardy hybrids by Miss Winifrid Walker are excellent speci- 

 mens of colour-printing : the smaller pictm-es of recently introduced 

 Chinese species bv Miss Eunice Breniiaii(l. some of them not pre-
