The anthers and stigmas of _M. rotundifolia_ are both matured together; and the styles lengthen, and bend downwards, causing the stigmas to twine themselves among the numerous stamens in such a manner that the flower can hardly fail to fertilise itself. Further, if we watch the flowers of these two species on a sunny day, we find that insects visit the flowers of _M. sylvestris_ freely, while they are seldom attracted to the smaller and less conspicuous blooms of _M. rotundifolia_. The third species referred to is the Musk Mallow (_M. moschata_), so called from the musky odour given off from all parts of the plant, especially when rubbed or crushed. It is often seen in hedgerows, but is not so common as the other two just described, and seems to be rather partial to gravelly soils. The plant is hairy, of a pale green colour, with an erect stem from two to three feet high. The flowers are large and beautiful, of a rich rose colour, and crowded towards the top of the stem. The fruit is hairy. A white variety is occasionally seen, and this is not uncommonly grown as a garden flower. The time of flowering is July and August. [Illustration: THE COMMON MALLOW.] Some three species of Geranium (order _Geraniaceæ_) have already been described among the spring wayside flowers, and these were listed at the commencement of the present chapter as continuing to bloom during the summer; but now we have to note other interesting flowers of this and an allied genus as essentially summer bloomers. The first of these is the Round-leaved Crane's-bill (_Geranium rotundifolium_), which rather closely resembles the Dove's-foot Crane's-bill, but is not nearly so plentiful. It is a downy plant, growing from six to twelve inches high, and flowering in June and July. The flowers are usually nearly half an inch across, of a pink colour; and the petals are _not_ notched. This species is represented on Plate III, Fig. 1. In dry pastures and on stony wastes we may see the Bloody Crane's-bill (_Geranium sanguineum_), which, though not common, is very widely distributed in Britain. It has a thick, woody stock; numerous more or less decumbent stems, from one to two feet long, clothed with spreading hairs; and round leaves, divided quite to the base into five or seven deeply-cut segments. The flowers are solitary, dark crimson (occasionally pink) in colour, with hairy sepals terminating in fine points; slightly notched petals about twice as long as the sepals; and ten stamens, five of which are larger, and glandular at the base. This species flowers during July and August. [Illustration: THE MUSK MALLOW.]
