11 s'agit exclusivement dans cette note d'especes du genre 

 Strychnos dont 16 seulenient sur 80 existent dans l'Elat independant du 

 Congo. L'une des plus anciennement connue pour cet usage est le 

 Strychnos Icaja Baillon, du G a b o n. Contrairement ä l'opinion de 

 Baker (Fl. of trop. Afr.), M. d e Wilde man considere cette espece 

 comme tres distincte du 5'. densiflora Baill., du Fouta Djallon et du 

 5. Dewevrei Gilg, mais plus proche du 6". kipapa Gilg, tous deux de 

 l'Etat independant. Ces diverses especes sont egalement toxiques. II 

 en est de meme pour les 5. Dekindtiana Gilg^ de 1' Angola, 5". piingcns 

 Solereder, et 6". omphalocarpa Gilg, de l'Est africain 



La note se termine par une description du 5. Dewevrei plus detaillee 

 que Celle de Gilg, et par la description de trois especes nouvelles du 

 Congo independant, dont la toxicite et ignoree : vS. Gilletii (p. 743), 

 suberosa (p. 744), variabilis (p. 745). Les deux premieres, tres voisines 

 l'une de l'autre ont leurs affinitees du cote de 5". Cawalhoi Gilg ; 

 i'autre se rapprocherait de 5. cerasifera Gilg. Henri Hua.

Ceylon. 



This well known Journal dealing with tropical agriculture and now 

 in its twenty-fifth volume, has recently been become the official maga- 

 zine of the Ceylon Agricultural Society. Mr. John Ferguson has 

 retired from the post of editor which he has occupied for so long, and 

 Dr. J. C. Willis, the Director of the Botanic Gardens of Ceylon has 

 undertaken the control of the Journal. At the same time great changes 

 have been effected in paper^ type and printing and particularly in illu- 

 strations. Whiist mainly written with special reference to conditions in 

 Ceylon, touch is maintained with agriculture in other parts of the tro- 

 pics and the usefulness of this Journal in the future shouid be even more 

 World wide than it has been in the past. W. G. Freeman. 



Wright, H., Citronella and Lemon grass in Ceylon. 

 (Tropical Agricuiturist. Vol. XXV. p. 222— 225. July 1905.) 



In this paper read before the Ceylon Agricultural Society the author 

 reviews the present position of the citronella and lemon grass oil In- 

 dustries in the colony. The cultivation of citronella grass has hitherto 

 been confined to the low lands of the South and South West districts, 

 but it is shown to succecd at elevations of at any rate 2000 feet in the 

 Central Province. The necessity of checking adulteration and of impro- 

 ving the process of distilling are insisted upon. 



Lemon grass is also briefly discussed. The articie is illustrated öy 

 a photograph of lemon grass cultivation and by elevation and plan of a 

 citronella oil still. W. G. Freeman.
