Description
Summary:The ovules, seeds and pollen grains of 24 Rafflesia specimens from nine species were examined. The ovules and seeds of all specimens showed similar shapes and structures. Rafflesia ovules are J-shaped and incompletely anatropous, while the seeds are chestnut-shaped. The pollen grains are small (10-25 ?m in diameter), prolate-spheroidal and subprolate, monoporate, with a smooth surface and no ornamentation.
