The naine is derived from yypos, succus, and xaeros, fructus, in allusion to the 
juicy nature of the fruit, which forms so remarkable a peculiarity in this genus. 
In the calyx, both of Tropæoleœ and Capparidec, that variety of imbricate 
zestivation generally obtains which is termed equitant, the anterior and 
posterior lobes, which are also most frequently the largest, overlapping and 
inclosing the lateral ones. The petals in both families are often unequal, 
lobed and unguiculate; and the anthers adnate, erect, tetragonal, having 
prominent valves, with involute edges, so as to give them the appearance of 
being eomposed of four cells. In habit Cleome and Tropwolum are not unlike; 
the leaves in both are peltately lobed; and in C. violacea and in the genus 
Cleomella the flowers are strictly axillary and solitary ; and were it not that 
there is a scandent species of Cleome, namely, C. longipes of DeCandolle, the 
climbing habit of Tropæolum might have been urged against the approxima- 
tion of the two families. In the flowers of some species of Cleome, such, for 
example, as C. gigantea, particularly in the bud state, a considerable gibbosity 
is apparent at the base of the calyx, which may be regarded as an indication 
of a spur. On the leaves of Cleome glandulosa similar glands occur to those 
which are observed in Magallana, in which genus, it is to be remarked, the 
ovarium is bilocular, and the stigmata consequently reduced to two.
