Fig. 3 in The uncinate viscidium and floral setae, an evolutionary innovation and exaptation to increase pollination success in the Telipogon alliance (Orchidaceae: Oncidiinae)

Fig. 3 Pollinarium morphology and viscidium morphology. Top, drawn (dorsal and ventral views, respectively) of pollinaria from diverse Telipogon species, all with uncinate viscidia (a Telipogon koechliniorum, b Telipogon huancavelicanus, c Telipogon phuyupatamarcensis, d Telipogon peruvianus). Bottom, Telipogon peruvianus (left) and Trichoceros muralis (right) viscidia. Note the uncinate and cochleariform viscidium, respectively. Viscidium of Trichoceros muralis is not in its natural position to make structure clearer. Photograph by Carlos Martel
