Vascular diagram of Fenerivia heteropetala (bundles indicated for perianth and outermost stamen whorl only).
Abbreviations, with numbers used to differentiate between organs of the same whorl: S, sepal; OP, outer petal; MP, middle petal; IP, inner petal; CVS, cortical vascular system; St, stamen. Redrawn from Deroin [13].

Flower morphology of Fenerivia capuronii.
(A) Adaxial view of flower, showing the six linear inner petals. (B) Abaxial view of flower, showing the three broad ovate sepals and the flange (arrowed). Reprinted from [16] under a CC BY license, with permission from Lars Chatrou, original copyright 2011.
Figure 3.
Serial transverse sections through the receptacle of Fenerivia capuronii, showing floral vasculature.
(B–F in sequence, from base to apex of receptacle.) (A) Section through flower, above receptacle, showing positions of stamens and carpels relative to the sepals, outer petals and inner petals. (B) Base of the receptacle, showing six groups of vascular bundles. (C) Base of the receptacle, showing the flange. (D) Position where the sepals are connected, showing the first appearance of vascular traces. (E, F) Position where the sepals and outer petals are connected, showing their median bundles and lateral bundles. Abbreviations for organs (upper case) and vascular bundles (lower case), with numbers used to differentiate between organs of the same whorl: F, flange; S, sepal; OP, outer petal; IP, inner petal; b, bundle; lb, lateral bundle; mb, median bundle.

(A–F in sequence, from base to apex of receptacle.) (A–D) Position where the sepals, outer petals and inner petals are connected, showing the median bundles and lateral bundles of the sepals and bundles leading to the petals. (E) Vascular bundles leading to outer petal 3. (F) Vascular bundles leading to inner petal 2 and outer petal 2. Abbreviations for organs (upper case) and vascular bundles (lower case), with numbers used to differentiate between organs of the same whorl: S, sepal; OP, outer petal; IP, inner petal; b, bundle; lb, lateral bundle; mb, median bundle.
