|Title:||Bat Pollination Of Encholirium Glaziovii, A Terrestrial Bromeliad|
|Abstract:||The many-flowered, brush-like spikes of Encholirium glaziovii, a ground-dwelling pitcairnioid bromeliad of the "campo rupestre" formation of southeastern Brazil, was observed being pollinated by the glossophagine bat, Lonchophylla bokermanni, in the Serra do Cipó (Minas Gerais). Nectar feeding was while hovering, and the pollen was preferentially transferred by the bat's snout. The floral pattern is chiropterophilous; unlike known tillandsioid bat flowers, stamens and style are protrusive beyond a small, persistent perigon, and anthesis, apparently protogynous, extends over several nights, with gradual onset and cease. Although various other flower-visiting Chiroptera are known to occur in the area and are not mechanically precluded from exploiting Encholirium glaziovii, no one seems to compete with Lonchophylla bokermanni. This species, a trap-liner, habitually forages in open habitats, a possible reason for its exclusiveness.-Flower details of two other species of Encholirium from the same locality including one with the bat pollination syndrome, are given. © 1989 Springer-Verlag.|
