NATURAL HISTORY OF PLANTS. 



as types of a particular geniis,^ tlie corolla not only being well 

 developed, but the pieces united among themselves for some dis- 

 tance. The gamopetalous character is not real, although the petals 

 may be united for a considerable distance, or even to the summit, 

 in a singular species from tropical Western Africa, J. Heudelotii^ 

 whose indehiscent fruit has a mesocarp thicker and more fleshy,^ 

 than the other Jatrophas^ This genus, thus limited, contains 

 some seventy species,^ natives of all warm regions. 



Jatroplia (Mozinna) cordata.

They are frutescent or, partly herbaceous, with alternate leaves, 

 accompanied by stipules sometimes glandular, petiolate, with limb 

 entire, dentate, or lobed, digitinerved, and sometimes even as in J. 

 Heudelotii, compound of 8-5-folioles. The flowers, rarely dioecious, 

 are arranged in ramified clusters, often corymbiform, and composed 

 of cymes, the female flowers, when they exist, occupying the 

 centre. Most of them are milky plants. Those of the section 

 Cnidoscolus are generally covered with glandular hairs with a 

 burning juice.

3 Which occurs, at least during a certain 

 time, in other Jatrophas, such as J. Curcas (fig. 

 164). The result of the indehisoence of the 

 pericarp is here, as often elsewhere, the slight 

 development of the aril. 



* I believe it is of the same plant that 

 Mueller has made [Prodr, 1111.) his Rieinodai- 



droii africaims, whose name, according to us 

 hecomes a section of Jafropha.
