Inflorescence and floral ontogeny of the perennial, herbaceous crop Crocus sativus L. were studied using
epi-illumination light microscopy. After production of leaves with helical arrangement a determinate
inflorescence forms which becomes completely transformed into a single terminal flower. In some cases,
bifurcation of the inflorescence meristem yields two or three floral meristems. The order of floral organs
initiation is outer tepals – stamens – inner tepals – carpels. Stamens and outer tepals are produced
from the lateral bifurcation of three common stamen-tepal primordia. Within each whorl, organs start
developing unidirectionally from the adaxial side, except for the stamens which begin to grow from the
abaxial side. Specialized features during organ development include interprimordial growth between
tepals forming a perianth tube, fusion at the base of stamen filaments, and formation of an inferior ovary
with unfused styles.
