of the Common Bean {Vicia x Fabtf ; Fr., Five commune). In this 

 plant (figs. 13S-142) the flowers are hermaphrodite irregular and 

 resupinate. The receptacle forms a shallow cup lined with glandular 

 tissue. In the bottom of this is inserted the gyna^ceum, while its 

 oblique edges bear the calyx, corolla and androceum. The calyx is

gamosepalous membranous, slightly gibbous below and posteriorly, 

 and divided above into five narrow unequal lobes, becoming longer 

 as they approach the back of the flower. In the bud the anterior 

 lobe overlaps the two lateral, which in turn overlap the two posterior. 

 These last are valvate by their posterior edges (fig. 139). 3 The 

 petals, free and alternating with the calyx lobes, together form what 

 is termed a " papilionaceous" corolla. The posterior petal, unlike the 

 rest (fig. 140), and termed vexillum or " standard" (Fr., etendard), is
