10 NATURAL HISTORY OF PLANTS. 
Tricholobus consists of trees from the Indian Archipelago’ and 
Cochin China,’ with alternate imparipinnate, glabrous or hairy leaves ; 
the flowers are in axillary or terminal racemes of cymes. As yet 
three species are known. 
As in the genus Rowrea, with the greater number of species 
possessing plurifoliolate leaves, we find some species in which they 
are unifoliolate ; so in some species of Zricholobus from India and 
Malaysia, to which the name Hlipanthus* has. been given, the 
leaves have only asingle leaflet: but as all the essential characters of 
flower and fruit are identical, we can only make this a section of 
the genus Zricholobus. Four species are known, natives of India 
and Malaysia.‘ 
This small order, as we have just studied it, dates no great way 
back. A. L. pe Jussizu® followed his predecessors in putting 
Connarus, Omphalobium, and Cuestis, the only genera of the order 
then known, in Zerebinthacee. It was R. Brown who, in his cele- 
brated work on the plants of western tropical Africa,’ proposed in 
1818 to found an order Connaracee, which should include the three 
genera Connarus, Cnestis, and Rourea. He considered that the 
insertion of the stamens was only doubtfully hypogynous ; but that 
the most important character of the group lay in the attachment of 
the collateral ovules by a basilar or subbasilar hilum ; while, i in the 
seed the radicle of the embryo was superior. Thus, he distinguished 
Connaracee sharply from Terebinthacee, making the ovule and seed 
orthotropous in the former, and anatropous in the latter. Kouwrn’ 
in 1824 simply followed Brown, admitting Connaracee without 
comment as a distinct order just like Juglandee, Amyridee, &c. ; 
including the three genera given by R. Brown, and adding Brunellia® 
and Brucea as “ genera Connaraceis afinia.” ENDuIcHER’ retained the 
narus, Manotes, &c., it may be much higher. 
This is the case in 7. fulvus Bu., whose ovule 
has hence been described as anatropous. In 
this species the micropyle tips the very long 
tapering conical apex of the ovule, and is quite 
superior, while the attachment of the ovule is at 
nearly one-third its length from its base. Hence 
the anatropy is very incomplete, and especially 
less complete than in certain species of Manotes.
