Pollination bio­logy of a Chloraeinae orchid

The pol­lin­a­tion bio­logy of very few Chloraeinae orch­ids has been stud­ied to date, and little is known about pol­lin­ator beha­viour. Sanguinetti et al. study the floral fea­tures, breed­ing sys­tem and pol­lin­ator beha­viour in Chloraea mem­branacea, one of the few non-Andean spe­cies in the group. They find that this spe­cies is nec­tar­less, dis­plays labellar pro­jec­tions involved in scent emis­sion and is self-compatible, although pollinator-dependent. The main pol­lin­at­ors are Halictidae bees, which visit more than one flower per inflor­es­cence and thus pro­mote self-pollination (geitono­gamy). Some female bees can be observed trans­fer­ring pol­len from the pol­lin­arium car­ried on their dor­sum to their hind legs; a rare event in orchid pollination.
