			Inasmuch as perfume serves as an attraction to the more highly specialized, aesthetic insects, not required by the spiraeas, our meadow-sweet has none, in spite of its misleading name. Small bees (especially Andrenidae), flies (Syrphidae), and beetles, among other visitors, come in great numbers, seeking the accessible pollen, and, in this case, nectar also, secreted in a conspicuous orange-colored disk. When a floret first opens, or even before, the already mature stigmas overtop the incurved, undeveloped stamens, so that any visitor dusted from other clusters cross-fertilizes it; but as the stigmas remain fresh even after the stamens have risen and shed their abundant pollen, it follows that in long-continued stormy weather, when few insects are flying, the flowers fertilize themselves. Self-fertilization with insect help must often occur in the flower's second stage. The fragrant yellowish-white ENGLISH MEADOW-SWEET (S. ulmaria), often cultivated in old-fashioned gardens here, has escaped locally. In long, slender, forking spikes the GOAT'S-BEARD (Aruncus Aruncus - Spiraea aruncus of Gray) lifts its graceful panicles of minute whitish flowers in May and June from three to seven feet above the rich soil of its woodland home. The petioled, pinnate leaves are compounded of several leaflets like those on its relative the rose-bush. From New York southward and westward to Missouri, also on the Pacific Coast to Alaska, is its range on this Continent. Very many more beetles than any other visitors transfer pollen from the staminate flowers on one plant to the pistillate ones on another; other plants produce only perfect  |
