TWO-LEAVED TOOTHWORT; CRINKLE-ROOT (Dentaria diphylla) Mustard family
Flowers - White, about 1/2 in. across, in a terminal loose cluster, the formation of each similar to that of bulbous cress. Stem: 8 to 15 in. high. Root stock: Long, crinkled, toothed, fleshy, crisp, edible. Leaves: 2, opposite or nearly so, on the stem, compounded of 3 ovate and toothed leaflets; also larger, broader leaves on larger petioles from the rootstock. Fruit: Flat, lance-shaped pods, 1 in. long or over, tipped with the slender style. Perferred Habitat - Rich leaf mould in woods, sometimes in thickets and meadows. Flowering Season - May. Distribution - Nova Scotia to the Carolinas, west to the Mississippi.
Clusters of these pretty, white, cross-shaped flowers, found near the bloodroot, claytonia, anemones, and a host of other delicate spring blossoms, enter into a short but fierce competition with them for the visits of the small Andrena and Halictus bees then flying to collect nectar and pollen for a generation still unborn. In tunnels underground, or in soft, partially decayed wood, each busy little mother places the pellets of pollen and nectar paste, then when her eggs have been laid on the food supply in separate nurseries and sealed up, she dies from exhaustion, leaving her grub progeny to eat its way through the larva into the chrysalis state, and finally into that of a winged bee that flies away to liberty. These are the little bees so constantly seen about willow catkins.
Country children, on their way to school through the woods, often dig up the curious, long crisp root of the toothwort, which tastes much like the water-cress, to eat with their sandwiches at the noon recess. Then, as they examine the little pointed projections on the rootstock, they see why the plant received its name.
Another toothwort found throughout a similar range, the CUT-LEAVED TOOTHWORT, or PEPPER-ROOT (D. laciniata), has its equally edible rootstock scarcely toothed, but rather constricted in places, giving its little tubers the appearance of beads strung into a necklace. Its white or pale purplish-pink cross-shaped flowers, loosely clustered at the end of an unbranched stem, rise by preference above moist ground in rich woods, often beside a spring, from April to June - a longer season for wooing and working its insect friends than the two-leaved toothwort has attained to - hence it is the commoner plant. Instead of having two leaves on its stem, this species spreads whorls of three leaves, thrice divided, almost to the base, the divisions toothed or lobed, and the side ones sometimes deeply cleft. The larger, longer petioled leaves that rise directly from the rootstock have scarcely developed at flowering time.
SHEPHERD'S PURSE; MOTHER'S HEART (Bursa Bursa-pastoris; Capsella Bursa-pastoris of Gray) Mustard family
Flowers - Small, white, in a long loose raceme, followed by triangular and notched (somewhat heart-shaped) pods, the valves boat-shaped and keeled. Sepals and petals 4; stamens 6; 1 pistil. Stem: 6 to 18 in. high, from a deep root. Leaves: Forming a rosette at base, 2 to 5 in. long, more or less cut (pinnatifid), a few pointed, arrow-shaped leaves also scattered along stem and partly clasping it. Preferred Habitat - Fields, roadsides, waste places. Flowering Season - Almost throughout the year. Distribution - Over nearly all parts of the earth.
>From Europe this little low plant found its way, to become the commonest of our weeds, so completing its march around the globe. At a glance one knows it to be related to the alyssum and candy-tuft of our gardens, albeit a poor relation in spite of its vaunted purses - the tiny, heart-shaped seed-pods that so rapidly succeed the flowers. What is the secret of its successful march over the face of the earth? Like the equally triumphant chickweed, it is easily satisfied with unoccupied wasteland, it avoids the fiercest competition for insect trade by prolonging its season of bloom far
