When tbe description of this genus was published in the Kev: Bulletin in 1910, 

 I was quite unaware of the genus Spondianthus, described by Kngler in Bot. Jahrh. 

 xxxvi. 215 (1905), and referred by him to Anncardiacece. He lecognised two 

 species, S, Preussii, from theCameroons, and S. //la ber, from Angola. Subsequently 

 (in Notizblatf Konifjl. Bot. Oart. Berlin, 1911, «o. 48, 240) he transferred the 

 genus to Eiiphorhiacece, at the same time recognising its identity with si)Ocimeus 

 distributed by Pierre under the MS. name of Megaharia Trillesii and M. ohoratum^ 

 the former of which was jmblished as a name only by I)e Wildeman ; lie reduced his 

 S.f/laber to a variety of JS. Preussii, and added another species, S. obovatus, founded 

 upon Megabaria obovatum, Pierre, MS. The lust sjjccies, however, represents quite a 

 distinct genus, and was described and figured as such by the writer in Hook. Ic. PI. 

 t. 2929 (1911) as Protome gab aria. The following corrections and additions are 

 therefore necessary : 



Megabaria should be Spondianthus. 



1. Megabaria Trillesii, Pierre ex Hutchinson, becomes Spondi- 

 anthus Preussii, Engl, in Bot. Jahrb. xxxvi. 216 (190.')). 



Add to synonymy: Spondianthus Preussii, forma oblongifolius and v&t. glaber, 

 Engl, in Notizbl. Kcinigl. Hot. Gart. Berlin, 1911, no. 48, 242.
