The vegetative parts of the plant are covered with simple hairs ( indument ). The opposite leaves are elongated-lanceolate or linear and rolled up at the edge.

The hermaphrodite flowers are radially symmetrical with a double flower envelope . The five sepals are ovate or lanceolate and pointed with a length of 5 to 9 millimeters. The petals are longer than the sepals. The five white petals are 5 to 14 millimeters long.

The capsule fruit is spherical-ovoid with a length of 5 to 10 millimeters. The black or gray seeds are round kidney-shaped.
