NATURAL HISTORY OF PLANTS. 



Tlagianfhus divaricottus. 



It is also of sixty 1 American and African Mallows that the genus 

 Mai nisi rum- has been made. In some types of a section PhyUaii- 



thopliora? there is no epicalyx, and the carpels 

 open, or are provided with two dorsal prickles ; 

 but in the other species of Malvastrum these cha- 

 racters disappear, and to distinguish them from 

 the Mallows to which they 4 have been joined as a 

 section, there only remains the form of the 

 branches of the style, truncate or capitate at the 

 apex. It is impossible for us to consider the 

 characters above as sufficient to distinguish a 

 genus, and therefore we admit four sections in 

 the genus Malva, 6 such as we have just defined it. 

 Beside the Mallows are ranged three genera 

 in a subseries of Eumahece, which differ but 

 little from them. These are, first, the Marsh 

 Mallows {Guimauvcs) (fig. 141), having the same 

 llowers and all the same characters of vege- 

 tation, but whose involucre is formed of from 

 six to nine leaves, united below into a gamo- 

 phyllous envelope ; then Sidalcca and Ncqjcea, 

 which have no involucre, the former remarkable 

 by its androceum, with double column, the 

 outer one being pentadelphous, while the inner 

 stamens form a distinct bundle composed of an 

 indefinite number of pieces ; the latter is 

 characterized by its dioecious flowers. 



Sida, having the general characters of the Mallows, forms the 

 head of a distinct subseries, Sidea, because the ovule is descending, 

 with the micropyle looking inwards, instead of being ascending,
