Abstract: Th is work provides a summary of the typical fl oral structure of subtribe Hyptidinae (Lamiaceae), in which both style and stamens are declinate within or near the concave anterior corolla lobe. Cross-pollination is facilitated by protandry, acting in conjunction with the explosive release of the stamens and pollen. In contrast, we report that in the three species of the genus Eplingiella we found individuals with either resupinate or non-resupinate fl owers, which represents a novel fl oral dimorphism. In the… Show more

“…This is a floral dimorphism found in three Eplingiella spp. (Lamiaceae) (Harley et al 2017). In this floral system, approximately half the population have exclusively resupinate flowers (upside down) while the other individuals have normal, non-resupinate ones.…”

“…However, resupination seemed to be a fixed characteristic, being expected that all plants of a population would have only resupinate flowers (Gibbs 2017). In resupinate dimorphy, however, the presence of resupination is the difference between morphs of the same population (Harley et al 2017;Gibbs 2017). It is likely that this floral dimorphism promotes disassortative pollination between morphs (Gibbs 2017), however it is yet to be directly tested.…”

“…1 a, c). Stimulus-directed twisting has been referred to by a number of terms, including strophism (Snow 1962 ), heliotropism (Iino 2001 ), resupination (Dines and Bell 1994 ; Harley et al 2017 ), and torsion (Borchers et al 2018 ), with slightly different implications. Here, we use the word “twist” as a simple expression of the deformation represented in Fig.…”

“…Twisting of the basal part of the leaf adjusts the orientation of the adaxial surface of the lamina to face the light source, enhancing photosynthesis (Koller 1990 ; Terashima and Saeki 1985 ). Flower orientation is also adjusted by twisting to attract specific pollinators (Darwin and Darwin 1880 ; Harley et al 2017 ).…”

“…In a new twist on resupination, Harley et al . (2017) recently discovered an unusual dimorphism in Eplingiella , a shrub in the mint family: in one morph, plants display their bilaterally symmetric flowers in an upright direction, while in the other, a turn of the pedicel orients flowers upside down, promoting cross‐pollination between morphs. What is learned by studying and describing organisms can launch new research arenas (Greene, 2005).…”
