(2848) Epidendrum flabellum-veneris J. Koenig in Retzius, Observ. Bot. 6: 57. Jul–Nov 1791 [Angiosp.: Orchid.], nom. utique rej. prop. Typus: non designatus. The name Bulbophyllum lepidum (Blume) J.J. Sm. (Orch. Java: 471. 1905), based on Ephippium Blume (Bijdr. Fl. Ned. Ind.: 310. 1825), has long been applied to a species widely distributed tropical Southeast Asia, including India (Andaman Islands), Thailand, Myanmar, southern China, Vietnam, Laos, Cambodia, Peninsular Malaysia, Borneo, Java, Sumatra, Moluccas and the Philippines. (l.c.) described basis of collections from Indonesia. most distinctive diagnostic character separating B. its congeners is enlarged antrorse column wings, with rounded stelidia overtopped by wings (Smith, l.c. 1905; Holttum, Rev. Malaya 1: 415. 1957; Vermeulen & al., Borneo: 95. 2015). morphology makes it easily distinguished. Seidenfaden, his book König's names (Descr. Epidendrorum J.G. König: 39. 1995), noted that an earlier existed he considered applicable species. This was (in 1791) treated as conspecific later lepidum. new combination Cirrhopetalum (J. Koenig) Seidenf. Ormerod (‘flabelloveneris’) published (Seidenfaden, 1995) this transferred genus Aver. (Updated Checkl. Orchids Vietnam: 73. 2003). However, during taxonomic review we discovered identity unclear. We have not located any traceable original material herbaria are known preserve König specimens. Given vagueness description protologue, many sect. would fit description, something also pointed out al. (l.c.: 97), who preferred reject name, but did make formal proposal do so. In fact, Köenig) only occasionally used last 20 years, e.g., Seigerist (Bulbophyllum Allies: 173. 2001, “Cirrhopetalum flabellovernis”), Ong (Wild Penins. Malaysia: 2011), although listed several online nomenclatural databases (e.g., Plant List, http://www.theplantlist.org/tpl1.1/record/kew-222223; World Flora Online, http://www.wordfloraonline.org/search?query=Bulbophyllum+flabellum-veneris). contrast, explicitly defined consistently accepted almost all relevant national regional floras, other literature since publication Schlechter Repert.

Therefore, accordance Art. 56 ICN (Turland Regnum 159. 2018), formally propose outright rejection flabellum-veneris, first suggested 97).
