FIG. 2 in Diversity and evolutionary trends in the floral characters of some taxa of Scrophulariaceae sensu lato

FIG. 2. — Androecium conditions: A, five staminal traces splitted from the central stele supplying five fertile stamens (Verbascum letourneuxii Asch. & Schweinf.); B, posterior staminal trace suppressed in corolla tube (Antirrhinum majus L.); C, posterior staminal trace represented by staminode (Russelia equisetiformisSchlecht.& Cham.); D-F, five staminal traces diverged from both staminal dorsal carpellary complex and staminal lateral carpellary complex, and staminal ventral carpellary complex (Kickxia aegyptiaca (L.) Nábělek); G, five staminal traces diverging from staminal lateral carpellary complex and central stele (Linaria maroccana Hook.f.); H, five stamina traces diverged from sepal median staminal complexes, the posterior one suppressed in the corolla tube while the other four enter the four fertile stamens (Scrophularia xanthoglossa Boiss.); I, J, four staminal traces splitted from the central stele (Paulownia tomentosa (Thunb.)); K, four staminal traces splitted from the central stele and staminal lateral carpellary complex (Torenia fournieri Linden ex E. Fourn.); L, two staminal traces diverged from the central stele (Veronica anagallis-aquatica L.).
