Leaves of drymocallis convallaria
are divided into a terminal leaflet and well separated pairs of side leaflets; those at the base usually have three or four pairs, while stem leaves have exactly three. The terminal leaflet is obovate in shape. Leaves are dark green above, lighter green below, and they have a sparse covering of very short hairs. Leaflets are lined by large teeth, each terminating in a tiny red spike. Stems have a dense covering of hairs, supporting spherical glands.
Stems are topped by an open cluster of up to 40 flowers, held above the leaves. Flower stalks are up to one inch long, and glandular hairy, as are the five green sepals, often red-tipped. Flowers tend to open widely, with petals and sepals held at around 90 degrees to the stem; the white or pale yellow petals are non-overlapping, ovate to obovate in shape, sometimes shallowly notched at the tip. Sepals and petals are approximately equal in length; up to 0.3 inches. The yellow stamens have thin filaments and rounded anthers, and are arranged around a dome of tiny green to yellow carpels.
