Practice question

Conventional floral formula notation letters derive from classical organ terminology internationally standardized: K for calyx meaning sepals from French Kalyx, C for corolla petals, P for perianth when sepals and petals undifferentiated as tepals typical of monocots, A for androecium stamens male parts, G for gynoecium carpels female parts. Numerals denote merosity per whorl, parentheses indicate connation, line beneath or above G denotes ovary position. Hence G unequivocally represents innermost whorl with carpels and ovules, superior or inferior indicated respectively.
