Floral morphogenesis of Euptelea pleiosperma: (A) young stamens differentiated into anther with connective appendage, filament still very short; (B, C) stamen filaments more distinct after carpel formation; (D) young flower from above, connective appendages arrowhead-shaped; (E) mature stamen before dehiscence, showing longitudinal and horizontal extension of dehiscence lines (arrows), from side; (F) close-up of dehiscence line with horizontal extensions (arrows); (G) close-up of lower part of dehiscence line with horizontal extensions (arrows); (H) stamen primordia in the second flower from the bottom of an inflorescence appear first (arrows); (I) stamens in upper flowers are longer than those of lower flowers. B, Floral-subtending bract; C, carpel; F, flower; L, leaf; S, stamen; Sc, scale. Scale bars: A, D, H = 250 µm; B = 0·5 mm; C = 0·6 mm; E = 0·86 mm; F = 231 µm; G = 205 µm; I = 1 mm.
