TLDR
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

The dispersal effectiveness of the achene-pappus units of selected Compositae in steady winds with convection
J. C. Sheldon,F. M. Burrows +1 more
TL;DR: It is shown that the efficiency of dispersal is determined more by the fine details of the pappu geometry, which directly affects its aerodynamic properties, than by the size ratio of pappus to achene.

Pure Lines in the Study of Genetics in Lower Organisms
TL;DR: I have at times regretted giving forth this paper, but if it has in any way acted as an irritant to arouse the discussion foreshadowed in the present program, I shall feel that its good results outweigh its painful ones, and that it was worth while after all.

On the Floral Anatomy of some Compositæ.
TL;DR: The conclusion is reached that the ligulate florets of the Cichorieae have a comparatively constant type of vascular anatomy; that the tubular discflorets show a slightly greater variability, while the variation in the vascular anatomy of the bilabiate ray floretts is so great that they can be distinguished from the first two classes by the floral anatomy alone.
