Scape arising from an apical leaf axil, slightly compressed, narrowly 2-winged. Inflorescence a reduced panicle, 4.5--6.5 cm, 14--18-flowered; bracts linear-lanceolate to narrowly ovate, basal one ca. 2 cm, base 3--5 mm wide, membranous.

E Guangxi (He Xian).The present authors have not seen flowers of this species. Judging from the characteristics of the vegetative organs, it is similar to Ophiopogon jiangchengensis. Detailed observation of the flowers is necessary in order to ascertain whether or not the two species are really distinct. From Flora of China FOC Vol. 24 Page 256國內分布：廣西(賀縣)全球觀測記錄分布（數據來自GBIF）。
