In Malesian Sterculiaceae there was still one enigmatic monotypic genus unsolved, Leptonychiopsis (parviflora) Ridl., J. R. As. Soc. Str. Br. 82 (1920) 173; Fl. Mai. Pen. 1 (1922) 290, described after a specimen collected by a Malayan, 10 Dec. 1892, filed under Ridley 3743. Ridley distinguished this from Leptonychia by its 3-merous flowers. Recently I could borrow a type sheet from the Kew Herbarium to which is attached an ample pencil-drawn analysis. Unfortunately, it is hardly feasible to check this, as there is only one small bud on the specimen, which I did not dare to analyse.
