Syngonanthus densifolius var. majus showing erect, flexuous leaves in a rosette; B. Incurved leaves of S. incurvifolius; C. Leaf of S. densifolius var. brachyphyllus, showing achlorophyllous base. D–G. Comparison among sexual traits of S. incurvifolius and S. densifolius var. majus: D. Staminate flower of S. incurvifolius (trichomes removed from pedicel); E. Pistillate flower of S. incurvifolius with filamentous trichomes; F. Staminate flower of S. densifolius var. majus; G. Pistillate flower of S. densifolius var. majus exhibiting trichomes only at upper portion of the sepals; H. Capitulum detail of S. incurvifolius; I–J. Comparative vestiture of the petals in pistillate flowers: I. S. incurvifolius showing pilose petals; J. Petals glabrous in S. densifolius var. majus. Scale bars: B= 3 mm. C,H= 2mm. D–G, I–J: 500 μm.
