FIGURE 3 in Floral ontogeny of Magnolia (Magnoliaceae) species provides insights into floral evolution but does not possess taxonomic value at the genus level

FIGURE 3. Floral development of Magnolia maudiae. A. Floral primordium. B. Initiation of tepal primordia in the first whorl. C. Initiation of tepal primordia in the second whorl, early stage. D. Initiation of tepal primordia in the second whorl, later stage. E. Initiation of tepal primordia in the third whorl. F. Initiation of stamen primordia, early stage. G. Initiation of stamen primordia, later stage. G. Stamens petaloid (arrow) at the early stage. H. Occasional variations in tepal primordia in the third whorl. J. Initiation of carpel primordia (early), occasional variations in tepal primordia in the first and third whorls, and petal-like stamens (arrow). K. Initiation of carpel primordia (end). L. Carpel primordia with developing concavities. Abbreviations: floral primordium (f); tepal in the first whorl (t); tepal in the second 1 whorl (t ); tepal in the third whorl (t ); carpel (c); stamen (s). Scale bars: (A, B) = 100 μm; (C–K) = 200 μm; L = 500 μm.
