Dilophia ebracteata Maxim.

The records in FRPS and Fl. Xinjiang. (2(2): 91. 1995) of Dilophia ebracteata from Xinjiang are based on misidentified plants of D. salsa. The differences previously used to distinguish D. ebracteata (leaves entire, flowers ebracteate, ovary cristae longitudinal) from D. salsa (leaves dentate or pinnately lobed, flowers bracteate, ovary cristae transverse) do not hold, though the leaves in the latter species are more often sinuate, dentate, or repand, rather than entire.

Herbs glabrous throughout, rarely sepals puberulent. Stems erect, somewhat fleshy, simple from taproot, 1.5-10 cm tall. Leaves oblong-spatulate, linear-spatulate, or linear, (3-)5-10(-15) × (1-)1.5-3 mm, fleshy, base attenuate, margin entire, apex obtuse or rounded. Corymbs few to many flowered, only lowermost few flowers bracteate. Fruiting pedicels 3-10 mm. Sepals erect, broadly ovate, 2.5-3 × 1.5-2 mm, glabrous or subapically puberulent, margin broadly membranous, apex entire or minutely denticulate. Petals white, often with pink tinge outside, broadly obovate, 4.5-6 × 2-3 mm, apex rounded or subemarginate; claw to 3 mm. Filaments white, 2-3 mm; anthers ovate, 0.6-1 mm, the apicula ovate, 0.2-0.5 mm, apex rounded. Ovules 2-4 per ovary. Fruit valves oblong, glabrous, 2-2.5 mm, notch to 2 mm wide, apical cristae 4-12; replum 2-2.5 mm wide at base; style 0.2-0.3 mm. Seeds brown, broadly oblong or ovate, somewhat flattened, 1.8-2.2 × 0.9-1.2 mm. Fl. late Jun-Sep, fr. Aug-Oct.
