The genus Sladenia was referred to Ternstroemiaceae by Kurz and 
Thiselton-Dyer, Il.cc. It agrees on the whole with the Oe ae 
of that family given in Bentham and Hooker’s Genera Plantaru 
but differs from all the other genera in its dichasial cymes. The 
external appearance of the ovary and fruit recalls Lophira Oe ; 
and the filaments resemble those of some Dipterocarpaceae. Mr. L, A 
Boodle, who has kindly examined material, reports that the anatomical 
characters of the leaf and stem are not specially distinctive. They 
are such as might be found in members of a ptéain ee of different 
families, one of the latter being the Ternstroemiaceae. The anatomy 
does not agree well with that of the a one ne important difference 
being the absence of cortical bundles in S 
According to Engler’s latest scheme of Mimaibalick: * Sladenia 
should be referred to Parietales-Theineae, but cannot be assigned to 
any of the families included in that group. When mature fruit and 
seeds are known, it may be necessary to found a new family for its 
reception. Examination of young fruits suggests that the fruit may 
split septicidally into three cocci. 
Gil escription, referred Sladenia tentatively to Dilleniaceae, 
in which he also included Actinidia, Saurawja and Clematoclethra + 
These three genera are, however, so distinct from the remaining 
Dilleniaceae, that it seems better either to leave them in Ternstroe- 
miaceae,t or to treat them as an independent family viper 
Sladenia cannot be retained in Dilleniaceae in either case, as ae 
little in common with the subfamily Dillenioideae—T. A. Spr ce
