Extensive research on orchid fragrance components and their function both as pollinator attractants and as ethological isolating mechanisms has been carried out (Hills et al., 1968, 1972; Dodson, 1962;Dodson et al., 1969; Dressler, 1968; Williams and Dodson, 1972). Selective attraction, often species-specific, of male euglossine bees to various orchid flower fragrances has been confirmed by observing and collecting bees drawn to pads saturated with pure samples of floral fragrance components throughout Central America and northern South America (Adams, 1968; Dodson et al., 1969; Williams & Dodson, 1972). Gas chromatographic analyses of fragrances have shown that for every Catasetum species known to have a species-specific pollinator, the flowers of those species produce a species-specific fragrance, and that species of Catasetum which share identical floral fragrances attract the same pollinators (Hills et al.,1972). Such differential pollinator attraction by quantitative and/or qualitative variation in fragrance components can act as an isolating mechanism between sympatric species. Ethological isolation is often supplemented and reinforced by geographical, mechanical, temporal or seasonal, and/or ecological isolating mechanisms (Hills et aI., 1972). Earlier investigations with gas chromatography have shown that species of the Old World tropical genus Angraecum Bory also produce species-specific fragrances, though the pollinators are not euglossine bees (which are confined to the neotropics) but night-flying moths (Dodson et aI., 1969) This report will detail fragrance components in five Angraecum species and in two wellknown intrageneric hybrids.
