Species: Cerstium pumilum Curt
English Name: European chickweed
Annual or biannual plant. Single stem or stems are many, the base is rising slightly, to 20 cm tall, unbranched or upper part dichotomous branching, covered with numerous glandular and a few simple hairs. Leaves 4 - 15 mm in length, basal and lower leaves back ovoid, stem leaves ovate, narrowed in handles, other sessile, elliptic or broadly ovate back, fibrous. Blossoms gathered in loose false semi canopies formed by multi-blossom dihazii. Blossomd handles glandular, longer than the calyx, after flowering erect or pendulous. Bracts ovate, in the end to 1/8 of their height with webbed edge. Sepals lanceolate to oblong lanceolate, acute, 4 - 5 mm in length, tunicates up to 1/4 of length covered with simple and glandular hairs. Petals white, or almost equally longer than the sepals, the top to concave, branched veins. Stamens 10, sometimes less. 5 bars. Fruit box 6 - 8 mm in length, 1.5 - 2 times longer than the calyx. Seeds from 0.5 to 0.6 (0.8) mm in diameter, bright to dark brown, covered with fine warts. Volatility

Description: This introduced plant is a winter or spring annual about 2-6" tall. A mature plant becomes tufted at the base, sending up multiple stems. These stems are green and pubescent. The opposite leaves are up to ¾" long and about half as much across. These leaves are broadly oblong or ovate-oblong, green, and pubescent; they have conspicuous central veins, smooth margins, and sessile bases.
The upper stems terminate in small cymes or individual flowers; sometimes the lower cymes branch into secondary cymes of flowers. The peduncles and pedicels of these cymes are light green and pubescent. At the base of each peduncle, there is a pair of green leaf-like bracts. These bracts are broadly lanceolate-oblong or lanceolate-ovate, pubescent, and smooth along the margins; some of the upper bracts have thin translucent margins toward their tips (i.e., they are slightly scarious). These translucent margins are more apparent in mature or dried-out plants than young specimens. The flowers at the tips of the pedicels are up to ¼" across when they are fully open. Each flower has 5 white petals, 5 green sepals, 5 white styles, and 5 stamens with pale yellow anthers. Each petal has several pale lines at its base, while its tip is notched. The sepals are lanceolate and hairy; their margins are translucent. The blooming period occurs during the spring and lasts about 1 month; this is one of the earliest wildflowers to bloom during the spring. The flowers open up during spring days that are sunny and warm. Some plants begin to bloom when they are only 1" tall. Each flower is replaced by a cylindrical capsule containing many small seeds. Each seed capsule is straight to slightly curved; there are 10 small teeth along its upper rim. The seeds are brown, somewhat flattened, and minutely warty or pebbly. The root system consists mostly of thin fibrous roots. This plant spreads by reseeding itself and it often forms small colonies.
