FIGURE 4 in Floral ontogeny of Magnolia (Magnoliaceae) species provides insights into floral evolution but does not possess taxonomic value at the genus level

FIGURE 4. Floral development of Magnolia figo. A. Floral primordium. B. Initiation of one tepal primordium in the first whorl. C. Initiation of tepal primordia in the second whorl. D. Initiation of stamen primordia, early stage. F. Initiation of stamen primordia later stage. G. Initiation of carpel primordia, early stage. H. Initiation of carpel primordia, later stage. I. Carpel primordia with developing concavities. Abbreviations: floral primordium (f); tepal in the first whorl (t 1); tepal in the second whorl (t 2); carpel (c); stamen (s).
