Interspecies variation in floral fragrances emitted by tropical Ficus species
Phytochemistry, 1999In this paper we examine if fig species emit specific compounds in order to attract pollinating wasps. Volatile compounds released by receptive figs from 13 tropical Ficus species were identified. They are mainly terpenoids, but also include benzenoids and non-terpenoid oxygenated aliphatic compounds.

Variation in Floral Fragrances and Morphology: Incipient Speciation in Cycnoches?
Botanical Gazette, 1983Variation in flower color, labellum morphology, and fragrance are described for four Panamanian species of Cycnoches previously considered to be C egertonianum Batem A lack of odor detectable by nose or gas chromatography (GC) from C. aureum Lindl and distinct odor profiles obtained for C dianae Rchb.

Identification of Petunia hybrida cultivars that diurnally emit floral fragrances
Scientia Horticulturae, 2006Abstract In order to identify genetic resources for breeding fragrant petunias for use as bedding plants, volatile compounds released by day from the flowers of 40 commercial Petunia hybrida cultivars were analyzed using a solid-phase micro-extraction technique coupled with GC–MS.

Interspecific variation in floral fragrances within the genus Narcissus (Amaryllidaceae)
Biochemical Systematics and Ecology, 1997To improve our understanding of the floral biology, pollination, and systematics of the genus Narcissus, a comparative study was made of flower volatiles from nine species native to southern Spain using headspace collection and GC-MS analysis. The species fell into three fragrance types based on the identity o! their major volatiles.

Subcritical CO2 extraction of floral fragrance from Quisqualis indica
The Journal of Supercritical Fluids, 2008Abstract Quisqualis indica syn. Q. Densiflora , family Combretaceae, is a large woody, scandent shrub. The composition of the floral extract of Q. indica with subcritical CO 2 is compared with that of extracts obtained by different conventional methods such as distillation with water and extraction with pentane.

Floral fragrance compounds of some anthurium (ARACEAE) species and hybrids
Phytochemistry, 1998Abstract Floral fragrance compounds of five species Anthurium armeniense, A. fragrantissimum, A. lindenianum, A. ochranthum and A.roseospadix, and three hybrids of A. armeniense were studied using headspace adsorption and solvent extraction for sample preparation followed by capillary GC and GC-MS analysis.

Motor patterns of male euglossine bees evoked by floral fragrances
Animal Behaviour, 1971Abstract During pollination of certain orchids, tropical euglossine bees collect fragrant chemical substances from the flower with forelegs, transfer it to the midlegs, and finally to a cavity in the hindleg tibia, as indicated by motion picture analysis. The activities of Eulaema cingulata, E.

Fragrance of Canada Thistle (Cirsium arvense) Attracts Both Floral Herbivores and Pollinators
Journal of Chemical Ecology, 2006The evolution of floral scent as a plant reproductive signal is assumed to be driven by pollinator behavior, with little attention paid to other potential selective forces such as herbivores. I tested 10 out of the 13 compounds emitted by dioecious Cirsium arvense, Canada thistle, including 2-phenylethanol, methyl salicylate, p-anisaldehyde ...
