Sections by Jenna L. Froelich (left, oblique longitudinal section) and Michael A. Terry (right, longitudinal section)

Section by Marnie J. Freeman, transverse section of distal region of sepal; secretory idioblasts with amber-colored granular deposits are charasteric of distal regions of the pistillate flower sepals.

Sections by Jenna L. Froelich (left) and Michael A. Terry (right); longitudinal sections of petals; the palisade-like epidermis resembles that of basilaminar glands and glandular foliar teeth, suggesting a secretory function for the narrow, spike-like petals.

Section by Jenna L. Froelich; style base; note secretory idioblast with amber-colored granular deposits.

Sections by Marnie J. Freeman (left) and Michael A. Terry (right); ovary wall; note stellate trichomes on external surfaces; the innermost two layers of the ovary wall will differentiate into sclereids instrumental in the explosive dehiscence of the mature fruits.
