PART 2 Investigations of Flowers of Episcia lilacina
________________________________________________________________
General Description of the Flower
Until today, the legitimate pollinator of Episcia lilacina could not be observed. Because of the
mutual adaptions between flowers and pollinators, the flower shape as well as different
morphological characteristics can indicate possible visitors. In this chapter these indications were
analysed and therefore some pollination groups were taken into consideration, others were
excluded.
Figure 23 Episcia lilacina; habit.
Results: Episcia lilacina produces single flowers of zygomorphic symmetry (Fig. 23). The
pedicel is pilose and of greenish to reddish colour. The calyx consists of five sepals, which are all
of equal size, free to the base, erect, pilose, and of greenish to reddish colour. The shape of the
sepals is narrow lanceolate, the margin is entire.
Regarding the corolla, five petals are fused together to form a long tube, which apically bears
an oblique limb of rounded petal lobes. The limb is divided into two upper and three lower lobes.
The entrance into the tube is a narrow slit so that the flower type may be classified as keyhole-
