4. Getonia Roxburgh, Pl. Coromandel. 1: 61. 1798.

萼翅藤属 e chi teng shu

Calycopteris Poiret, nom. illeg. superfl.

Lianas woody. Leaves opposite or subopposite; leaf blade elliptic or lanceolate to ovate. Inflorescences axillary, simple or branched spikes crowded toward branchlet apex and forming a large, often dense, bracteate panicle. Calyx tube proximally ellipsoid, 5-ridged, distally campanulate; lobes 5, triangular-lanceolate at anthesis, persistent and much enlarged in fruit. Petals absent. Stamens 10. Fruit narrowly ovoid, dry, longitudinally 5-ridged; persistent calyx lobes spreading, winglike, elliptic to oblanceolate or narrowly so.

One species: Bangladesh, Cambodia, China, India, Laos, Malaysia, Myanmar, Singapore, Thailand, Vietnam.

The correct name for this genus is Getonia, not Calycopteris as given in FRPS (53(1): 3. 1984). Lamarck (Tabl. Encycl. 1: t. 357. 1793) published a plate captioned "Calycopteris" comprising an illustration with analysis. Under Art. 42.1 of the Vienna Code a name of a genus and its single species may be simultaneously validly published with a descriptio generico-specifica, in place of which, before 1908, an illustration with analysis is acceptable (Art. 42.3 and 42.4). However, Art. 42 does not apply to the publication of a genus name alone, so Lamarck did not validly publish any names. The text corresponding to the plate was published later (Poiret, Tabl. Encycl. 2: 485. 1819), but, before that, Poiret (Encycl., Suppl. 2: 41. 1811) published a description of the genus and recombined Getonia floribunda Roxburgh (1798) as its only species, C. floribunda. In citing G. floribunda, Poiret included the type of the then unispecific Getonia, so that Calycopteris was nomenclaturally superfluous when published and is therefore illegitimate (Art. 52.1).
