Jaltomata darcyana rotate flower development. a, b Stages A–C: Sepals develop asymmetrically from the abaxial side, and once of similar lengths, grow from their base to form a fused tube. c Stage C: Removal of sepals reveals development of petal and stamen primordia. d, e Stage D: Petals grow freely but begin to develop trichomes. f, g Stages E–F: Carpels become fused during gynoecial development. hk Stages F–G: Petals are congenitally fused at the base just above the stamen insertion point (h, i), but then become “superficially fused” via interlocking trichomes along their lengths by ~ 3 mm flower diameter (j, k). Scale bars = 100 μm, and bud diameter is provided in bottom right panel. s, sepal; p, petal; st, stamen; tri, trichome; fus, corolla fusion; fil, anther filament; g, gynoecium; sty, style
