* Colura cylindrica Herzog SPECIMEN EXAMINED. — Vietnam. Annam, Central Highlands Region, prov. Kon Tum, sur les feuilles d’un arbre haut de 10-11 m, 20.III.1941, Poilane s.n. (PC [PC0764720]). ILLUSTRATION. — Herzog 1952: 196, fig. 26. NOTES The specimen is in bad state but still well identifiable. This species belongs to Sect. Harmophyllum Grolle, and was described from Ecuador, based on small fragments. Jovet-Ast (1954: 259) had already noted, that it is very close to the Asian Colura mosenii Steph. The only minor difference is in the shape of the fingerlike lobule sac, being cylindrical in C. cylindrica while narrow conical in C. mosenii. Pócs (1991) has found C. cylindrica also in East Africa, Tanzania. If the two taxa prove to be synonymous, then the earlier name: C. mosenii is to be used. C. mosenii was described from Java and has since been discovered in the Caroline Islands (Inoue & Miller 1965) and Malaysia (Pócs & Lee 2016), while Colura cylindrica in South America with the Caribbean and Tanzania in East Africa (see map in Pócs 1991). Now, it is new to Vietnam.
