anything that tapers from a circular section to a point, such as a wafer shell used to contain ice cream
the reproductive body of conifers and related plants, made up of overlapping scales, esp the mature female cone, whose scales each bear a seed
a similar structure in horsetails, club mosses, etc
a small cone-shaped bollard used as a temporary traffic marker on roads
