ascendent, with inferior exterior micropyle. Styles often gynobasic, 
united above into a single column. Fruit drupaceous or dry, inde- 
hiscent. Seeds exalbuminous.—(4 genera.) 
IT. Evrsemmrx.—Gyneceum with carpels united among them- 
selves, with two ovules in each cell; micropyle superior and exte- 
rior. Fruit drupaceous, with five stones. Seeds albuminous.— 
(1 genus.) 
III. LuxemBurG1æ.—Gynæceum generally eccentric, with parietal 
placentas (2-5), more or less prominent, multiovulate upon the edges. 
Fruit capsular, septicidal, polyspermous. Seeds albuminous. — 
(6 genera.) 
All the species of this last series, fifteen or sixteen in number, are 
natives of the tropical regions of South America. The /uthe- 
mideæ, three or four in number, belong entirely to Malaysia. The 
only known Zet¢ramerista is from Sumatra. The genus Z/vasia is 
entirely American. All the Ochnas belong, on the contrary, to the 
tropical or subtropical regions of the Old World. The genus 
Ouratea has the most extended geographical area. It is represented 
in tropical America by about two-thirds of its species, that is to 
say, some fifty; but it is met with in Asia and Africa, and in 
Oceania is found that particular form constituting the subgenus 
Brackenridgea. 
The only common characters of all the members of this small 
family are the woody consistence of the stem, the alternation of the 
leaves, the presence of stipules, the convexity of the floral receptacle, 
the independence of the petals, and the absence of the glandular 
disk. But there are other characters very frequent, without being 
absolute. These are principally: the simple nature of the leaves,’ 
their mode of nervation, the secondary nerves being crowded, parallel, 
oblique or nearly perpendicular to the principal nerve, and the fine, 
regular marginal cuts, like the teeth of a saw, sometimes glandular,’ 
the prolongation of the receptacle into a column of variable height 
between the insertion of the androceum and gynæceum. ‘The other 
characters are subject to variations; those drawn from the orga- 
nization of the gynæceum and fruit have been used, as we have seen, 
to distinguish the series or tribes ; the others to separate the genera.
