dc.descriptionReproductive biology and pollination of Stanhopea lietzei and Stanhopea insignis were studied ill a semi-deciduous mesophytic forest in the Serra do Japi (SJ), and in the coastal plain of Picinguaba. both in the State of Sao Paulo. Brazil. Floral morphology, pollination, breeding system and fruit set of both species were investigated. S. lietzei and S. insignis are pollinator-specific, being pollinated by male bees of Eufriesea (Apidae, Euglossini), which collect the fragrance produced by pluricellular osmophores at the base of the saccate hypochile. S. lietzei and S. insignis were pollinated by Eufriesea pulchra and Eufriesea purpurata, respectively. Observations using substances present in the floral fragrance of both studied species as chemical baits were also performed. E purpurata was attracted by benzyl alcohol, the major compound of the perfume of S. insignis, while E pulchra was attracted by none of the compounds used. Both Studied Stanhopea are self-compatible but pollinator dependent. Self-pollination, however, tends to be avoided by floral mechanisms. In experimental self- and cross-pollinations the proportion of fruit abortion was high and related to resource limitation. The reproductive success of S. lietzei and S. insignis was low as a consequence of deficient pollen transference while pollinator scarcity was the main factor. (C) 2008 Elsevier GmbH.
