2253. Wernham, H. F. Dewevrella congenesis sp. nov. Jour. Botany 58: 80-81. 1920. — 

 This genus of the Apocynaceae was founded as recently as 1907 by Db Wildeman, and the 

 only known species is D. cochliostema. The present new species, the second in the genus, was 

 collected by M. A. Nannan in the same district, namely, Boyeka at the equator. — K. M. 

 Wiegand. 



2254. Wernham, H. F. Tropical Amesican Rubiaceae. — XIII. Jour. Botany 58: 105-108. 

 1920. — The genus Coupoui is considered in this number. A historical account is given of the 

 genus beginning with the original description by A^jblet in 1775. It has been very poorly 

 understood owing to a lack of flowering material. The genus is here held to belong to the 

 Rubiaceae though by earlier authors it was placed in the Apocynaceae and Myrtaceae. A 

 key is given to the three known species, also synonymy and notes on distribution. C. brasili- 

 ensis is described as new. — K. M. Wiegand. 



2255. Wiegand, K. M. Eupatorium purpureum and its allies. Rhodora 22:57-70. 

 1920. — By the examination of the material ordinarily recognized as Eupatorium purpureum, 

 the writer has worked out a treatment for this section of the genus. Four species and one 

 variety have been confused under the general name E. purpureum L., now separated 

 as E. verticillatum Lamarck, E. maculatum L., E. maculatum var. foliosum (Fernald) comb, 

 nov., E. purpureum L., and E. falcatum Michx. The facts and the history as to the synonymy 

 and nomenclature of these species are given in considerable detail as well as a key for their 

 identification. — James P. Poole. 



2256. WiLMOTT, A. J. Erythraea scilloides Chaubard. Jour. Botany 58 : 23. 1920.— The 

 author discusses the proper name for a plant found in Pembrokeshire, taking exception to the 

 disposition of the plant made by Druce. — K. M. Wiegand.
