Flowers in clusters of 2--5, campanulate, 8--11 mm in diam.; pedicel 6--8 mm, articulate near middle. Tepals pale violet, ovate, 4.8--5 × 3--3.2 mm, apex slightly revolute. Filaments 0.2--0.3 mm; anthers narrowly ovate-deltoid, 3.5--4 × ca. 1.5 mm, free. Style 4--4.5 mm. Seeds pale violet at maturity, ellipsoid, 7--10 × 5--7 mm. Fl. Aug--Sep, fr. Oct--Feb.

This species is similar to Ophiopogon siamensis M. N. Tamura (Acta Phytotax. Geobot. 49: 27. 1998), from N Thailand, but differs in having longer bracts and shorter filaments and style. Ophiopogon siamensis has bracts less than 1 cm, filaments 0.7--1.1 mm, and style 5--5.4 mm. Further studies are needed to ascertain whether or not these two species are really distinct.
