Liú Méng 劉蒙
Late-Northern-Sòng scholar and chrysanthemum-connoisseur, native of Péngchéng 彭城 (Xúzhōu). His office and exact lifedates are not recorded. His one surviving work, the Liúshì júpǔ 劉氏菊譜 (KR3i0031) — the first surviving Chinese chrysanthemum-treatise — is dated by its own preface to a Chóngníng jiǎshēn (1104) visit to Lóngmén (the famous Buddhist grotto-cliff at Luòyáng), where Liú visited the home of his fellow-connoisseur Liú Yuánsūn 劉元孫 and they jointly examined-and-discussed chrysanthemum varieties.
He was a Huīzōng-period person; Wáng Détóng’s 王得臣 Zhūshǐ 麈史 (early Northern-Sòng bǐjì) already cites his discussions. Jiāo Hóng’s 焦竑 Guóshǐ jīngjí zhì misorders Liú Méng after Fàn Chéngdà (1126–1193) — an error per the Sìkù editors, who confirm Liú as a Huīzōng-period figure (i.e., c. 1100–1125).
