Description

edit

Stems vary between five and fifty centimeters in length, with thread-like to linear leaves generally alternate: the leaves are typically not planar and not clasping. Cymes are characteristically open and pedicels are somewhat thread-like and ascending. The flower has five sepals, whose margins may be minutely gland-toothed. Five petals are widely spreading between one and twelve millimeters in dimension. These yellow, white or rose colored petals each manifest three minute scales at the inner base. There are five stamens and four to six ovary chambers; styles number two to three. Fruits have a smooth surface exterior.
