anatomy snapdragon flower

Flower diagram of snapragon.
Drawn by Kurt Stueber

Here is a small collection of pictures from wildtype or near wildtype flowers of Antirrhinum majus. Traditionally the cultivar "Sippe 50" is defined to be the "wildtype" or standard for Antirrhinum. Pictures shown here come mostly from other cultivars, which do not significantly differ in their anatomical structure from "Sippe 50".
Here are two pictures (from phu) which display a longitudinal cut throught the snapdragon flower with the names of the individual flower parts in English

or German
