Pinewoods Drymary

Drymaria depressa has been treated as a variety of D. effusa, from which it differs in a number of respects, as indicated in the key.

Plants annual, herbaceous, gla-brous or minutely puberulent, not glaucous. Stems ascending to erect, generally branching at base, 0.5-5 cm. Leaves opposite; stipules ± deciduous, simple, subulate, 0.5-1.2 mm; petiole absent or nearly so; blade orbiculate to spatulate (basal leaves) or oblong (cauline leaves), 0.3-1 cm × 0.2-3 mm, base attenuate, apex rounded to acute. Inflorescences terminal, congested to open, 3-25+-flowered cymes. Pedicels mostly shorter than subtending bracts at maturity. Flowers: sepals with 3 prominent, ± parallel, apically confluent veins, lanceolate, oblong, or ovate (herbaceous portion ± oblong), 1.8-2.3 mm, ± equal, apex blunt or rounded, hood at ± right angle to apex, formed in part by scarious margins, glabrous; petals 2-fid for ca. 2 their length, 1.5-2.8 mm, 3/ 4-1 times as long as sepals, lobes 1-veined, vein unbranched, linear, trunk absent, base gradually tapered, apex rounded. Seeds light reddish brown to tan, snail-shell- to teardrop-shaped, 0.5-0.6 mm; tubercles minute, rounded.
