The nectary tube varies from alone a few millimeters, up to several centimeters, and is an important floral appropriate in morphological classification. Stamens alter from 2 to 7, and their number, position about to staminodes, and curvature are used to analyze alone species. There are 5 stigmata in the style. For the ample assortment in annual morphology, see amount 1 of Röschenbleck et al.
