Sticky Drymary

Drymaria viscosa is often attributed to S. Watson ex Orcutt; however, as B. D. Parfitt and W. C. Hodgson (1985) correctly stated, C. R. Orcutt (1886) merely mentioned the name and did not publish it validly.

Plants annual, herbaceous, viscid, not glaucous. Stems prostrate, diffusely branched proximally, 5-20 cm. Leaves appearing whorled or opposite; stipules deciduous, simple, filiform, 1-1.5 mm; petiole absent or nearly so; blade linear to narrowly lanceolate, 0.3-1.5 cm × 0.5-1.5 mm, base attenuate, apex rounded to acute. Inflorescences axillary and terminal, somewhat congested, 4-7-flowered cymes. Pedicels shorter to longer than subtending bracts at maturity. Flowers: sepals with 3 obscure veins arcing outward at midsection and ± confluent apically, lanceolate to narrowly ovate (herbaceous portion similar), 2.3-3 mm, subequal, apex obtuse (herbaceous portion acute to acuminate), not hooded, stipitate-glandular; petals 2-fid for 1/ 2+ their length, 1.8-2.2 mm, 3-1 times sepals, lobes 1-veined, vein unbranched, spatulate, trunk absent, base gradually tapered, apex rounded. Seeds brown abaxially, transparent (or white embryo visible) adaxially, snail-shell- or teardrop-shaped, 0.6-0.7 mm; tubercles minute, rounded.
