Look at the floral diagram below and select the property which are true to the flower.
Flower shows valvate aestivation
In the above floral diagrma, we see that all the 4 whorls are inmultiple of 5. Therefore the flower is pentamerous. The flower also has both the male (third whorl from outside) and female reproductive units (innermost whorl), hence it is bisexual. We see the the margins of sepals and petals do not overlap, indicating valvate aetivation.
