The needle-like leaves are arranged opposite at least to the middle, which is typical for this species. The 5 to 11 millimeters wide and 0.5 to 11 millimeters long leaf blades are bald, hairy or glandular and often rolled up at the edge. There are two stipules and small leafy shoots in the leaf axils for each leaf. Stipules and deciduous leaves act like leaves standing in whorls.

The hermaphroditic flowers are radial symmetry and five-fold with a double flower envelope . Of the five sepals , the two outer ones are very small and the inner three are large. The five free, yellow petals are 5 to 8 millimeters long. There are many stamens present.
