An interesting method of pollen collecting by bees from flowers with tubular anthers National Institute of Agronomic Research
Michener, Charles D..
Varous plants have anthers which open by apical pores; in some (Cassia in the Leguminosae and Solanum wendlandii in the Solanaceae ) the pollen does not readily come out of these pores, yet is abundant and is collected and used by females of certain large and moderate sized bees. A bee obtains pollen by curling its body over the ends of the anthers and then vibrating its wings (wings held in folded position). The vibrations, which produce a loud sound, cause the pollen grains to shoot out of the pores in the anthers ; many of them lodge on the body of the bee from which they are transferred to the pollen-carrying scopal hairs. A vibrating knife blade touched to the anthers also causes pollen to be discharged through the pores. The bees concerned are all...

Rapports entre l'évolution florale d'un lavandin et l'essence produite National Institute of Agronomic Research
Barbier, M.E.C..
Au cours de recherches sur les rapports existant entre le Lavandin et l'Abeille, nous avons été conduits à examiner en rapport avec l'évolution florale de la plante, les évolutions du rendement et de l'indice de réfraction des essences obtenues par des distillations successives. Ces travaux ont porté sur la variété de Lavandin "Z" ·sélectionnée au Domaine de Puberclaire (B.-A.), et cultivée au Laboratoire Apicole de Nice (A.-M.). Les 200 plants mis en place en 1951 ont atteint au moment des essais en 1957 leur plein développement.

The receptive surface of the angiosperm stigma National Institute of Agronomic Research
Heslop-Harrison, Yolande; Shivanna, K.R..
This paper reports upon a study of the characteristics of the receptive surfaces of angiosperm stigmas,covering almost 1000 species of about 900 genera of sorne 250 families. In both monocotyledons and dicotyledons the major subdivision is into those stigmas which are 'dry' at maturity, having a hydrated, proteinaceous extracuticular layer or pellicle but no free-flowing secretion, and those which are 'wet' bearing such a f1uid secretion when in the receptive state. Further subdivision may be made taking into account the nature of the surface cells-whether or not the receptive surface is papillate or smooth, and if papillate, whether the papillae are unicellular or multicellular. When the genera are c1assified according to these criteria, various taxonomie...
