Stem-leaves alternate, senile; leaf-blades oblanceolate to linear-oblanceolate, (0.5-) 1-3 cm x 1-6 mm, suba-cute, acute or cuspidately acuminate at the apex, tapered to a rounded-cuneate base, entire or subentire, pahninerved. Pseudumbel 3-5-rayed, the rays many times bind, often with a few axillary rays below the pseudumbel; pseudumbel-leaves 3-5, whorled, usually resembling the upper stem-leaves but often somewhat broader; ray-leaves opposite, ovate-lanceolate to ovate-deltate or -rhombic, often-falcate, cuspidate to aristate at the apex, cuneate, rounded or ± truncate at the base, subentire or minutely serrulate, progressively smaller distal-ly. Cyathia shortly pedunculate to subsessile, yellow or orange-pink. Glands transversely elliptic-oblong, crescentic, hornless or shortly 2-homed, yellow or greenish-yellow.
