Lasianthus sylvestris Blume f. latifolius Miquel, Ann. Mus. Bot. Lugduno-Batavi 4: 248. 1869 ["latifolia"]; L. hiiranensis Hayata; L. lei Merrill & F. P. Metcalf ex H. S. Lo.

Forests, shaded and wet places. Hainan, Taiwan [Indonesia (Java, Sumatra), Malayasia (Peninsular), Philippines, Singapore, Thailand, Vietnam].
This taxon was treated as Lasianthus tomentosus Blume by King and Gamble (J. Asiat. Soc. Bengal, Pt. 2, Nat. Hist. 73: 130. 1904), Ridley (Fl. Malay Penin. 2: 161. 1923), Craib (Fl. Siam. 2(2): 219. 1934), and H. Zhu (Acta Bot. Yunnan. 20: 155. 1998), which may be due to the authors following two misidentified sheets in K. These two specimens, which are labeled as Horsfield s.n. [Rub. 50] from Java, are indicated as "L. tomentosus Blume" with Miquel’s handwriting and also were cited as such in print (Miquel, Fl. Ned. Ind. 2: 318. 1857). Miquel (loc. cit. 1869) later changed his mind and considered that they were not the same as L. tomentosus. The type materials of L. tomentosus are only in Leiden and there are no overseas duplicates. After examining Malesian specimens and carefully comparing with the type of L. tomentosus, it is recognized that the taxon that was mistaken for L. tomentosus has conspicuous, strigose, linear-lanceolate stipules, 4-merous flowers, hirsute and verrucose drupes with 4 pyrenes, and is more closely related to L. trichophlebus than L. tomentosus. The taxon differs from L. trichophlebus by having only dense hirsute hairs on the branches and pubescent hairs on the abaxial leaf surface. It is better, therefore, to treat this taxon as a variety of L. trichophlebus.
