formed of ten stamens, superposed, five to tlie sepals, and five to the 

 petals ; the latter are longer than the former. They have their 

 filaments inserted below the ovary, united among themselves below, 

 then free and each surmounted by a bilocular, introrse, versatile 

 anther, dehiscing by two longitudinal clefts. Without the audroceum 

 and between the petals are found five glands of variable form. The 

 receptacle tapers to a thin columella supporting five oppositipetalous 

 independent carpels. They are each composed of a unilocular ovary, 

 whoso internal angle bears a placenta, on which is inserted a single 

 incompletely anatropous descending ovule with superior, exterior 

 micropyle." About halfway up the internal edge of this ovary is 

 inserted a free style, which soon joins with the other four styles in 

 forming a slender fluted column, with slightly swollen stigmatiferous
