Numerous long, slender thorns, often measuring a finger-length, distinguish the COCKSPUR or NEWCASTLE THORN (C. Crus-Galli), whose abundant small flowers and shining, leathery leaves, dull underneath, are conspicuous in thickets from Quebec to the Gulf. Immense numbers of little bees, among many other visitors, may be noted on a fine day in May and early June about this showy shrub or tree. Because it blooms later than its rival sisters, it has the insect wooers then abroad all to itself. While most of our beautiful native hawthorns have been introduced to European gardens, it is the WHITE THORN or MAY (C. Oxyacantha) of Europe and Asia which is most commonly cultivated here. Truly a shrub, like a prophet, is not without honor save in its own country. WHITE SWEET CLOVER; BOKHARA or TREE CLOVER; WHITE MELILOT; HONEY LOTUS (Melilotus alba) Pea family Flowers - Small, white, fragrant, papilionaceous, the standard petal a trifle longer than the wings; borne in slender racemes. Stem: 3 to 10 ft. tall, branching. Leaves: Rather distant, petioled, compounded of 3 oblong, saw-edged leaflets; fragrant, especially when dry. Preferred Habitat - Wastelands, roadsides. Flowering Season - June-November. Distribution - United States, Europe, Asia. Happy must the honeybees have been to find that the sweet clover, one of their dearest delights in the Old World, had preceded them in immigrating to the New. Immense numbers of insects - bees in great variety, wasps, flies, moths, and beetles - visit the little blossoms that provide entertainment so generous and accessible; but honey-bees are ever especially abundant. Slight weight depresses the keel, releasing the stigma and anthers therefore, so soon as a bee alights and opens the flower, he is hit below the belt by the projecting stigma. Pollen carried by him there from other clovers comes off on its sticky surface before his abdomen gets freshly dusted from the anthers, which are necessarily rubbed against while he sips nectar. On the removal of his pressure, the floret springs back to its closed condition, to protect the precious nectar and pollen from rain and pilferers. As the stigma projects too far beyond the anthers to be likely to receive any of the flower's own pollen, good reason is there for the blossoms guarding their attractions for the benefit of their friends, which transfer the vitalizing dust from one floret to another. By clustering its small flowers in spikes, to make them conspicuous, as well as to facilitate dining for its benefactors; by prolonging its season of bloom, to get relief from the fiercest competition for insect trade, and so to insure an abundance of vigorous cross-fertilized seed, this plant reveals at a glance some of the reasons why it has been able to establish itself so quickly throughout our vast area.
