256 ON THE GENUS CNEORUM. 
stamens, in number indefinite, have exceedingly short fila- 
ments, inserted under the disk, and there are no petals. 
Other differences will probably be found when the fruit and 
the embryo shall have been observed; nor is it possible to 
class this genus with certainty till it has undergone farther 
examination. 
The group, therefore, of which I now treat, will be com- 
posed solely of the genus Cneorum, or, as I propose to call it, 
of the sub-order Cneoree, which cannot be appended easily to 
any known family, though I am inclined to think that it may 
be considered as a division of Xanthoxylee. 
The Cneoree are extremely low, woody bushes, with very 
entire, lanceolate or linear, verticillately alternate leaves, gla- 
brous, or covered with hairs affixed by the middle. Its 
flowers, placed on very short axillary pedicels, are solitary 
or in pauciflorous cymes, the pedicels being either free or 
consolidated with the footstalks of the leaves, so that the 
flowers appear to proceed from the leaves themselves. 
These general appearances give to the Cneoree an air suf 
ficiently distinct from the other Terebintinous Orders, from 
which, nevertheless, through the structure of their flowers, it 
is impossible to separate them. Yet, still more than any 
other Terebinthacee, they approach Euphorbiacee by the 
ternary or quaternary disposition of their parts, by the po- 
sition of their ovaries, hanging as it were around a common 
axis, and by their ovules, solitary and suspended from the 
inner angle of the cell. In fact, they greatly resemble some 
Crotons ; and to this may be added their simple leaves and 
their medical properties,which latter, in C. pulverulentum, come 
near to those of the Cascarilla bark, the produce of a Croton. 
In respect to the position of their ovules, they agree with 
Zygophyllee and with Simarubee, as well as in some other 
points, their fruit being divided into superposed cells, as in 
Tribulus, and their stamens inserted in the gynophore, as in 
Guaiacum, which they resemble by their properties and the 
extreme hardness of their wood; but the presence of a peri- 
sperm distinguishes them from the latter Order, and its nature
