 Stamens rather short, numerous, erect, inserted on the throat 

 and the inner side of the apical portion of the calyx-tube, 

 glabrous, the outer longest ones about 9 mm. long ; filament 

 subulato-filiform, white then rosy-purpurascent below ; anther 

 minute, rounded, bifid at the base, introrse, yellow, 1mm. long
