  • a Nomarski microscopy of xylene-cleared gynoecia was used to count the number of ovules per carpel. Numbers in parentheses indicate the number of carpels examined.

  • b Numbers within parentheses indicate the number of gynoecia examined.

  • c Scanning electron microscopy analyses were used to visualize stigma and style.

  • d Light microscopy of tissue cross-sections was used to visualize septum formation.
