ABSTRACT

Gomiz, N.E., Torretta, J.P. & Aliscioni, S.S. 2014. Zygostates alleniana (Orchidaceae: Epidendroideae: Cymbidieae: Oncidiinae): Floral structure related to pollination. Anales Jard. Bot. Madrid 71(1): e002. The genus Zygostates Lindl. (Orchidaceae) comprises about 20 species of small Neotropical epiphytic plants, represented in its southernmost limit by the species Z. alleniana. In this paper, we studied morpho- logical and anatomical floral characteristics of this species related to pollination mechanism. We confirmed the presence of the unicellular trichomes on the base of the lip and side lobes secreting oil, constitut- ing a trichomal elaiophore. The oil is deposited beneath the cuticle at the apex of the trichomes forming small blisters. The oil could repre- sent a reward for the species Lophopedia nigrispinis, which would be a potential pollinator of Z. alleniana in a natural area within the geo- graphic range of this plant species. Moreover, we prove that the recon- figuration of the pollinaruim is due to the dehydration of the walls cell. This reconfiguration could favor cross-pollination mechanism already described for other species of the family Orchidaceae. Finally, we dis- cuss the floral characters present in Z. alleniana with closely related species.
