When the description of this genus was published inthe Kew Budletin in 1910, 
L was quite unaware of the genus Spondianthus, described by Engler in Bot. Jahrb. 
xxxvi. 215 (1905), and referred by him to Anacardiacea. He recognised two 
species, S. Preussii, from the Cameroons, and S. glaber, from Angola. Subsequently 
(in Notizblatt Kinigl. Bot. Gart. Berlin, 1911, no.48, 240) he transferred the 
genus to Huphorbiacee, at the same time recognising its identity with specimens 
distributed by Pierre under the MS. name of Megabaria Trillesii and M. obovatum, 
the former of which was published asa name only by De Wildeman; he reduced his 
S. glaber to a variety of S. Preussii, and added another species, S. obovatus, founded 
upon Megabaria obovatum, Pierre, MS. The last species, however, represents quite a 
distinct genus, and was described and figured as such by the writer in Hook. Ie. Pl. 
t. 2929 (1911) as Protomegabaria. 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 (1905). 
Add to synonymy: Spondianthus Preussii, forma oblongifolius and var. glaber,
