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...
