disappears entirely or nearly so ; they then generally stand erect 

 and parallel from the bottom of the single ovarian cavity. In the 

 section Homaloclados, the calyx becomes larger, gamosepalous, with 

 obtuse or even foliaceous lobes. The plants of this section are then 

 to Faramea what Galycosia and Cochnocahjx are to the true Uragoga, 

 from which it is difficult to distinguish them when the interlocular 

 partition is somewhat developed. These are all woody or sub- 

 shrubby plants from tropical America. 



YI. MOEINDA SEKIES. 



Morinda ^ (fig. 275, 276) has hermaphrodite or more rarely 

 polygamous flowers. These flowers are similar in construction to 

 those of Uragoga, usually 4, 5-merous, rarely more. The receptacle, 

 in the form of a small sac, is connate with those of the adjacent 

 flowers, the whole forming only one mass ; in the cavity is lodged 

 the ovary, which, instead of a single ovule in each of its two cells, 

 generally encloses two, collateral, ascending, ^ more or less. completely 

 anatropous, with the micropyle turned downwards and outwards. 

 The calyx, superior, is entire or more or less deeply divided ; the 

 corolla is valvate ; ^ the stamens, inserted near the hairy or glabrous 

 throat, or low^er,'' have a dorsifixed iutrorse anther, enclosed or 

 exserted ; the epigynous disk varies in form and appearance, and the 

 style is divided above into two stigmatiferous lobes or branches. In 

 the greater number of species,-^ a false vertical partition, developed 

 in each ovarian cell, between the two ovules, divides it into two
