Fig. 24 shows this tube laid open. Those that have 

 grown together by their filaments have to be further 

 studied. Are all the filaments grown together in 

 one bundle ? If so, the stamens are monadelphous 

 (Fig. 27). 



Are they grown together in two bundles ? Then 

 they are diadelphous (Fig. 28).

Are they in three or more bundles? Then we
