80 THE JOUKXAL OF BOTANY 



Acanthus iltcifolius L. Sogere region. No. 927. 



All the leaves are quite entire. 



JusTiciA Chalmersii Lindau, ex descript. Bosi-bosi, sine no. 



This is referred to § Adhatoda hj Lindau ; according to Clarke's 

 views, which seem better founded, it belongs to § Calophanoides. 



JusTiciA. CARDiocHLAMYS Lindau, ex descript. Mt. Sogere, 

 1750-1800 ft. Nos. 629, 782. 



A straggling and trailing shrub : flowers white or cream-coloured. 

 This Clarke would also have regarded as a member of § Caiophanoides. 

 Lindau places it in § Monechma, but as it has a relatively long ovary 

 with two ovules, both evidently developing into seeds, in each cell, 

 while Nees's main character for Monechma depends upon the short 

 2-seeded capsules, each cell with only a single e\ij.n or retinaculum, 

 it is clear that the plant has nothing to do with Monechma. 



Geaptophtllum Gilligani comb. nov. Justicia Qilligani 

 Bail. Sogere, 2500 ft. No. 51. 



Clarke (MS. in herb. Kew.) was the first to refer this plant to 

 its proper genus though, for what reason is not apparent, he gave it 

 a manuscript name of his own which, of course, is not published 

 here. From Q. pictum Griff, it can be told on sight by the narrow 

 lobes of the corolla-lips. 



Caltcacanthus Magnusianus K. Schum. Gawada, 3000 ft. 



An excellent specimen of this fine plant. Clarke has recorded 

 (MS. in herb. Kew.) his doubt whether the genus should not be 

 merged in Qraptophyllum relying, as would appear, upon the absence 

 of staminodes, but overlooking the corolla with its very long lips and 

 their short lobes. 



DEWEVRELLA CONGENSIS, sp. nov. 

 By H. F. Weenham. 



This genus of Apocynacece (§ EchitidecB) was founded so recently 

 as 1907 by De Wildeman, upon several specimens collected in the 

 equatorial region of the Congo-basin by members of the Laurent 

 Mission (De Wild., Miss. E. Laurent, i. 548, tt. clxiv, clxv) ; it is 

 dedicated to one of them, M. Alfred Dewevre. 



The single species described, D. cochliostema, was found in the 

 environs of Eala, which lies close to the point where the tributary 

 river Ikelemba empties itself into the Congo — that is at the Equator. 

 Collections were made in the same district in 1914 by M. A. Nannan, 

 of the Belgian Agricultural Department. I have described already 

 some llubiaceous novelties of this latter collection in this Jom'nal for 

 1918 (vol. Ivi. pp. 308-313). I now describe a second species of 

 Dewevrella^ readily distinguished from D. cochliostema by the size 

 and shape of the leaves and the calyx-segments, and gathered by 

 Nannan in the same district. 



Dewevrella congensis, sp. nov. 



Frutex altiuscule scandens cirrhosus, ramulis gracillimis junioribus 

 tenuissimis, minute rufo-puberulis demum necnon tardiuscule glabratis.
