Description

Calyptridium monandrum is a fleshy, flat annual herb producing short stems which extend along the ground or spread upright from a small taproot. Thick, spoon-shaped leaves occur in a basal rosette at the base of the stem, reaching up to about 5 cm in length. There are smaller leaves along the stems.
Small inflorescences sprout from the stem bearing many flowers, each with fleshy, triangular sepals and three pink or red petals only a few millimeters long. The fruit is a translucent, oblong capsule up to six millimeters long containing several shiny, black seeds.
