arranged in exstipulate false verticils. 1 The small flowers are 

 united in the axils of the leaves in cymes or glomerules, sometimes 

 capituliform. Four or five species 2 are known inhabiting Asia or 

 tropical Africa. 



Beside Giscckia is placed Liweum 3 (figs. 31-40). It has herma- 

 phrodite or polygamous flowers. The receptacle is slightly convex, 

 supporting a calyx 4 of five sepals, membranous upon the mar- 

 gin, arranged in quincuncial prefloration in the bud. With them 

 alternate five, four or three petals ? of variable size and shape, 

 which however sometimes quite disappear (figs. 32, 33). The 

 stamens vary in number from five to seven, eight or ten. In the 

 first case they are superposed to the sepals ; otherwise two or more 

 of them are replaced by a pair. 5

Each is composed of a filament united to the neighbouring fila- 

 ments for a very short distance, and a bilocular, introrse anther, 

 dehiscing by two longitudinal clefts. The gynseceum is formed of 

 two carpels, one flattened ovary being applied to the neighbouring 

 unilocular and uniovular ovary. The ovule is almost erect, supported 

 by a short funicle ; campylotropal, with the micropyle turned down- 

 wards and on one side. Two styles expanded and stigmatiferous 



1 They are like the calyx, riddled with small 

 whitish cystolites.

4 Here and there are tetramerous flowers. 



5 Thus, when there are seven stamens, it is 

 because the two stamens superposed to the outer 

 sepals are doubled.
