MR. BENTELM'S NOTE ON HOMALIUM. 
In drawing up my synopsis of the genus Homalium (p. 38), І had unfor- 
tunately overlooked M. L. B. Tulasne's “ Floree Madagascariensis Frag- 
mentum Alterum," in the ‘Annales des Sciences Naturelles,’ sér. 4, 
Botanique, vol. viii. p. 58, where five new species of Blackwellia, all from 
Madagascar, are described. I have not seen any specimens, so as to com- 
pare them with my own species; I can, therefore, now merely give bere 
the list, with the affinities suggested by the perusal of the descriptions. 
B. brachystylis (Tul. in Ann. Sc. Nat., sér. 4, vol. viii. p. 59), evidently 
closely allied to B. axillaris, Lam., or my Homalium azillare. 
B. Thuarsiana (Tul. l.c. р. 60), evidently very near to B. paniculata, 
‘Lam., or H. paniculatum, Benth. 
B. eriantha (Tul. l.c. p. 62) must also be closely allied to the same 
species. 
B. micrantha, Bois. (Tul. l.c. p. 63), seems to differ in its slender 
racemes and smaller flowers with broader sepals and petals. 
B. planiflora, Bois. (Tul. l.c. p. 64), probably differs still more in having 
the petals broader, longer, and more obtuse than the sepals.
