Mr. Reid records fruits of nine species from pre- glacial and interglacial beds in various parts of the country. In some species the male and female florets are on difi'erent plants (C dioica); in those which are regarded as most typi- cal there are one or more spikelets, consisting of male flowers above, and one or more of female flowers below; sometimes, however, the male and female florets are in the same spike, either the male above and the female below, or vice versa. In some species (Fig. 343) there are 2 stigmas, in others 3. The form of the one- seeded fruits or " utricles " also gives good specific characters. In some species, as, for instance, in C. paludosa, the stomata are pro- tected by a series of cuticular pegs (Fig. 344). These hold the air, thus keeping the stomata clear and dry.

C. pulicaria.—In this species and in C. pauciflora the fruits are narrow, pointed, and spreading or reflexed, so that they would readily be carried away by any passing Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lubbock, John, Sir, 1834-1913.
