The genus Stahlianthus was first established by Otto Kuntze in Revisio Generum Plantarum, published in 1891 with S. campanulatusKuntze as type species. After that, many species were described or transferred to this genus. Now, there are seven accepted names. All of them occur in mainland Southeast Asia, distributed in Myanmar, Laos, Vietnam, Cambodia, Thailand and also in South China. Five species were recorded in Thailand i.e. S. campanulatus, S. involucratus, S. macrochlamys, S. pediculatus and S. thorelii. The other two species were reported from adjacent places, S. andersonii in Myanmar and S. philipianus in Indo-china. Only few specimens of Stahlianthus were found in Thai herbaria. Most of them are without flower. Field survey and more collection are needed to revise this genus.
