Staminodes 3, of innermost whorl, cordate or sagittate, stipitate. Ovary always as long as style; style slender; stigma capitate or discoid, sometimes 3-lobed.

Cinnamomum sericans Hance (J. Bot. 15: 336. 1877) was described from China but could not be treated here because no material was seen by the present authors.
In addition, numerous names in Cinnamomum and Camphora based on Chinese material were published by Lukmanoff (Nomencl. Icon. Cannel. 1889). They are listed below. Type material needs to be located and identified in order to determine the correct application of these names.
Camphora: C. brongniartii Lukmanoff (loc. cit.: 23; China and Japan); C. decandollei Lukmanoff (loc. cit.: 23; China: Hong Kong); C. oldhamii Lukmanoff (loc. cit.: 23; China: Taiwan); and C. wrightii Lukmanoff (loc. cit.: 24; China: Hong Kong).
Cinnamomum: C. asa-grayi Lukmanoff (loc. cit.: 9; China: Hong Kong); C. baillonii Lukmanoff (loc. cit.: 10; China); C. barlowii Lukmanoff (loc. cit.: 16; China); C. calleryi Lukmanoff (loc. cit.: 16; China); C. goeringii Lukmanoff (loc. cit.: 16; China and Indonesia: Java); C. linnei Lukmanoff (loc. cit.: 15; China); C. lowii Lukmanoff (loc. cit.: 15; China); C. lucienii Lukmanoff (loc. cit.: 18; China and Japan); C. lunatum Lukmanoff (loc. cit.: 11; China); C. maximoviczii Lukmanoff (loc. cit.: 19; China); C. reinwardtii Lukmanoff (loc. cit.: 19; China); C. rougieri Lukmanoff (loc. cit.: 7; China and ?Myanmar); C. suaveolens Lukmanoff (loc. cit.: 9; China); and C. walteri Lukmanoff (loc. cit.: 18; China).
Cinnamomum esquirolii H. Léveillé (Fl. Kouy-Tchéou, 218. 1914-1915) is a synonym of Cocculus laurifolius Candolle in the Menispermaceae (see p. 13).
About 250 species: tropical and subtropical Asia, Australia, and Pacific islands; 49 species (30 endemic, one introduced) in China.
