Maranta Lujaiana, Hort. Lind. By (). K. {Ilcv. Hort. Beige, 

 t. xxvii. p. 241, col. pi.), nat. ord. Scitaminece ; native of Congo. — After 

 observing that this genus and Calathea supply several useful species, the 

 latter name being usually replaced by Maranta. the author refers to this 

 species and M. Liehrechtsiana, from the same locality, as introduced in 

 1901. As no flowers or fruit have been obtained, some doubt rests 

 with the generic name. Only a single species, M. arundinacea, is as 

 yet known from the Congo. The leaves of M. Lujaiana are ovate acute, 

 bright green above, and of a coppery orange colour below. It is used by 

 the natives for coagulating the latex of leaves into caoutchouc. — G. H.

 opinion over a wide area that the catching of moths by fruit-growers by 

 means of lanterns and other lights will do more harm than good, inas- 

 much as friends are killed as well as foes, and, further, that the worst

 trapped by these means. — C. C. H.
