 segments concave, sometimes mucronate or appendaged beneath the 

 apex, valvate or imbricate ; stamens generally equal in number and 

 opposite to the sepals (solitary in ForskoJilece), inflexed in bud ; 

 anthers 2-celled, introrse, opening longitudinally ; rudiment of ovary 

 variously developed. Female flower : Perianth 3-5-lobed or partite 

 with equal or unequal segments, or tubular, calycine, persistent and 

 very often increasing after pollination ; ovary free or sometimes
