Calyptrogyne ghiesbreghtiana spicigera

Description

Calyptrogyne ghiesbreghtiana, commonly called the coligallo palm Spanish for rooster tail, a reference to the form of the leaf, is an understory palm native to Central America and southern Mexico, where it grows in tropical rainforests.It is a stemless or short-stemmed palm with a trunk up to 2 m tall. The leaves are undivided, or pinnate with 3-9 leaflets, the terminal leaflet with a forked apex. The flowers are produced all year round, on upright inflorescences; they are monoecious, with complete temporal separation of the male and female stages. The flowers are pollinated by bats in the family Phyllostomidae. Because the flowers are made of a sweet chewable tissue like the pulp of a fruit they are much favoured by katydids Tettigoniidae, whose feeding reduces the number of flowers available to be pollinated The inflorescences host a species of mite (Acari) which live and reproduce on the inflorscence and travel to new inflorescences by hitching a ride on the flower-visiting bats. The behaviour of parasitising another animal for transport but not food is known as phoresy. A similar phenomenon which has been more comprehensively surveyed are the mites that live in flowers visited by hummingbirds and are phoretic on these flower-visiting birds
