Mr. N. E. Brown having published his plant (together with a 

 Yemen species) as generically distinct, and as the figure cited above in 

 Richard's ' Flora Abyssinica/ which he identified— so far as I can judge, 

 correctly— with the specimens of Schimper in the Kew Herbarium, is 

 inaccurate in respect both of the pollen and corona, it would seem 

 desirable to issue an illustration of his genus Tylophoropsis in ' Tconos 

 i^lantarum.' I must point out, however, that if the genus be main- 

 tamed it will involve a redistribution of the species hitherto included 

 Jn Tylojyhora, in which genus both M. Decaisne {DC. Prodr. viii. 610, 

 and Deless. Ic. Sel v. 82) and the authors of the 'Genera Plantarum 

 would allow the pollinia to be either erect or * a caudicuJa erecta pendula, 

 as e.y. in fyhisia, Dene., as figured in Delessert, I.e. It would be very 

 desirable to have all the species of Tylophora re-examined with a view 

 JO ascertain how far the direction of the pollinia may be variable. At 

 the base of the gynostegium in our plant are five very mmute teeth 

 alternating with the adnate lobes of the corona, as noticed by Mr. 



i^rown.^D. Oliver.
