The pollination biology of Drymonia serrulata was studied in central Panama. D. serrulata produces a small number of flowers daily for several months. Flowers are dichogamous with a one day male phase followed by a one day female phase. The average volume of nectar produced by a Drymonia flower over the two-day period was 264.4 Al (SD = 98.8, N = 4), a value much higher than has been reported for other bee-pollinated flowers. D. serrulata is completely self-compatible. Fruit set for between and…

Oil secretion and the pollination of Colpias mollis (Scrophulariaceae)
The strongly congruent geographic distributions of C. mollis and R. albifasciata and their close morphological fit suggest a long and close association between plant and pollinator.

Accessory Pollen Adhesive from Glandular Trichomes on the Anthers of Leonurus sibiricus L. (Lamiaceae)
Glandular trichomes on the anthers of Leonurus sibiricus produce a secretion that, when touched, is liberated at once and becomes sticky when in contact with the air, and the composition possibly differs from what generally distinguishes these glandulartrichomes, i.e. volatile oils that give these plants their particular smell.
Pollination biology and reproduction of Seemannia sylvatica (Kunth) Hanstein (Gesneriaceae) in the Serra da Bodoquena National Park, Mato Grosso do Sul
The protandry, coupled with the pattern of nectar production, characterized by low volume and solute concentration, which induces the pollinators to visit different flowers in a given circuit foraging, act maximizing the likelihood of cross-pollination in S. sylvatica.
Chiropterophily in Sinningieae (Gesneriaceae): Sinningia brasiliensis and Paliavana prasinata are bat-pollinated, but P. sericiflora is not. Not yet?
Pollination biology of Sinningia brasiliensis, Paliavana prasinata and P. sericiflora in south-eastern Brazil strengthens the statement that the bat syndrome in Sinningieae originated independently inSinningia Brasiliensis and inPaliavana species.
Non-Euglossine bees also function as pollinators of Sinningia species (Gesneriaceae) in southeastern brazil.
The results strengthen the idea of multiple origins for the pollination systems involving bees within this genus, which is highly supported by molecular phylogenetic analyses.
Clinal variability of oil and nectar rewards in Monttea aphylla (Plantaginaceae): relationships with pollinators and climatic factors in the Monte Desert
It is suggested that large-scale variation in rewards involves local optima throughout the species range, related to processes that operate in each ecoregion with their particular biotic and abiotic scenarios.
Characteristics of secretion of nectar in Pyrostegia venusta (Ker-Gawl.) Miers (Bignoniaceae)
Secretion patterns and characteristics of nectar of an Argentinian population of Pyrostegia venusta at different times of the day are described with respect to flower age, showing a concomitant increase in both concentration and volume in 1-d-old flowers, followed by a sharp increase in concentration and decrease in nectar volume in 2-D-old Flowers.
The floral biology of 3 species of Clusia sect. Chlamydoclusia and 3 species of Clusia sect. Cordylandra from Central Amazonia was investigated. The flowers of both sexes offer resin as the reward
Características de flores, néctar y visitantes de Kerianthera preclara (Rubiaceae)
Flower morphology and color -acercar pilose red corolla tube with stigma held aboYe the anthers- was indicative of a hurnmingbird pollination syndrorne and nectar was collected several times by the hummingbird Eupelomena macroura (Trochilidae).

Floral Convergence and Pollinator Sharing in Two Bee‐Pollinated Tropical Herbs
It is suggested that low flower density, exaggerated by extreme floral predation, has selected for floral similarity and pollinator sharing in these species, and increases effective flower density and nectar supplies, and probably increases the regularity and rate of pollinator visitation.
Variable Nectar Secretion in a Heliconia Species Pollinated by Hermit Hummingbirds
The average flower of Heliconia psittacorum, an herb pollinated by hermit hummingbirds on Trinidad, secreted 66.4 ,I of nectar; this volume was the flower's entire secretion, which suggested that considerable flower-to-flower variation existed.
Stratum, tree, and flower selection by tropical bees: implications for the reproductive biology of outcrossing Cochlospermum vitifolium in Panama.
Forager behavior in three patches of flowering Cochlospermum vitifolium and fruit, flower, seed, and ovule number on trees in six sites were used to test two incipient paradigms and study the role of bee pollinators in tree reproductive success.
Flowering Phenology and Diversity in Tropical Bignoniaceae
Most bee-pollinated species of Bignoniaceae secure their requisite pollinators by different strategies of flower production rather than morphologic differentiation, illustrating an overlooked mechanism for maintenance of high species diversity in tropical plant communities.
Aggression and Competition among Stingless Bees: Field Studies
Learning and recruitment appear to reinforce the effects of aggression on the spatial separation of foraging in competing colonies in different species of stingless bees.
