of the Common Bean (Vicia Faba’?; Fr., Féve commune). In this 
plant (figs. 138-142) 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 gynzceum, while its 
oblique edges bear the calyx, corolla and androceum. The calyx is 
Vicia Faba.

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). 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 vewdlum or “ standard” (Fr., étendard), is

not a genus, but a separate tribe, and calls 
Viciidee.

Lens, is referred by many authors to the genus 
Vicia, the calyx lobes are simply longer and 
narrower than in Vicia proper, and the ovary 
often contains but two or three ovules.
