Habitat in Agri Bonariensis locis arenosis (Commerson, Tweedie); in re- 

 gionibus Cisplatinis. A. de St.-Hilaire, Sello. 11 . (v. v. c. et s. sp. in 

 Herb. Linn. fil. et Lamb.) 



The name is derived from x^mz, succiis, and xccg7ro?,fructus, in allusion to the 

 juicy nature of the fruit, which forms so remarkable a peculiarity in this genus. 



In the calyx, both of Tropceolece and Capparidece, that variety of imbricate 

 aestivation 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 composed of four cells. In habit Cleome and Tropceolum 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 Tropceolum 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 3fagallana, in which genus, it is to be remarked, the 

 ovarium is biiocular, and the stigmata consequently reduced to two.
