Stipules very slightly adnate to the leaf-base. Peduncles stout, red or purple, 4-12 cm long, with a whorl or partial whorl of leaves at the top. Inflorescence lax, spreading, usually with 3 main branches again branched, the ultimate pseudoracemose. Flowers numerous. Perianth segments 3.5-4 mm long. Disc 3-lobed, the lobes acute or with a raised central point, red or orange. Stigmas large, red or orange, wedge-shaped, flat. Fruit 4-5 mm long, about as long as the perianth.
