NATURAL HISTORY OF PLANTS. 



Linconia and Audouinia, very closely akin, have a quite inferior 

 ovary lodged in the obconical receptacle ; a pentamerous perianth 

 of imbricated calyx and corolla, very much like that of the pre- 

 ceding genera, and five free epigynous included stamens. In 

 Audouinia 1 the anthers are elongated, introrse, with parallel cells ; 

 the ovary has three cells, each containing two collateral gemin- 

 ated descending ovules, with their raphes alwa} r s dorsal ; and the 

 style is simple trigonous, only divided at the apex into three stigma- 

 tiferous crenulations. In Linconia 2 each anther is surmounted by a 

 conical glandular prolongation of the connective, from which the 

 two divaricated cells descend obliquely. The ovary has but two 

 cells, with one or two ovules in each, or one quite empty ; and the 

 style is double. Thus the flowers come very near those of Brunia. 

 In both these genera they form short terminal spikes, and are 

 accompanied by a calycle of bracts. Only one species of Audouinia, z 

 and three of Linconia 4, are known, all South African. 



Berzelia h (figs 459-461) has the habit, foliage, and inflorescence in 

 globular capitula of Brunia, together with the same perianth and 

 androceum. But the inferior ovary has but one (uniovulate) cell, 

 and the style surmounting it is unsymmetrical, usually somewhat 

 bowed, with a shallow groove on one side, and towards the apex a 

 unilateral stigmatiferous surface ; the fruit is indehiscent. Seven 

 species" of Berzclia are known. 



LoncJtostoma, 1 which is not regarded by all authors as an undoubted 

 member of this group, has also a partly inferior ovary, with a penta- 

 merous double perianth and androceum. But the corolla seems 

 gamopetalous, its petals sticking together towards the base by means
