The variation in structure of styles and stamens is described and discussed in separate sections, while their functions in the pollen-presenting mechanism is considered partly in section D of the present chapter and partly in Chapter III which deals with the irritability of the mechanism.Abstract:
I the Compositas the mechanism involved in the presentation of pollen to the insect visitor includes both styles and stamens. These essential oi'gans ai-e discussed, therefore, in the present chapter, but for convenience the variation in structure of styles and stamens is described and discussed in separate sections, while their functions in the pollen-presenting mechanism is considered partly in section D of the present chapter and partly in Chapter III which deals with the irritability of the mechanism.read more

TL;DR: The discovery of the separated vortex ring provides evidence of the existence of a new class of fluid behaviour around fluid-immersed bodies that may underlie locomotion, weight reduction and particle retention in biological and manmade structures.

Inflorescence and floral ontogeny in asteraceae: A synthesis of historical and current concepts
TL;DR: The interpretation that all floral events on the capitulum take place in an acropetal or centripetal sequence is widely accepted, but many contradictory examples have been found.
Journal ArticleDOI
Repeat intercontinental dispersal and Pleistocene speciation in disjunct Mediterranean and desert Senecio (Asteraceae).
TL;DR: The loss of suitable land connections by the Miocene means that both New World lineages must represent long-distance dispersal, providing the first evidence of repeat intercontinental dispersal in a Mediterranean group.

TL;DR: The first volume of the Flora of India is due to the completion of the first volume as mentioned in this paper, which is an event of no small importance in descriptive botany and is the last of our possessions whose vegetable wealth botanists have undertaken to describe in a systematic order.
