Description

Pentanema spiraeifolium reaches a height of 30–80 centimetres (12–31 in). The middle leaves are oblong-elliptic and they measure 3–5 centimetres (1.2–2.0 in) of length and 1–2 centimetres (0.39–0.79 in) of width. The base of the leaves is not embracing the stem. The upper cauline leaves are erect, with a round base. The stem is erect and branched, with numerous flowers (two to twelve). The outer ones are ligulate and bright yellow, while the inner ones are tubular dark orange. The flower's attachment to the stalk (receptacle) is covered by clearly curved scales. The flowering period extends from June to August.
