19. Clerodendrum viscosum Vent., Jard. Malmaison 1: tab. 25. 1803.

Lectotypus (designated here): [INDONESIA. Java]: Hort. Cels, Ventenat s.n. (G [G00341557]!).

= Clerodendrum infortunatum L.

Notes. – When validating the name Clerodendrum viscosum Ventenat specifically wrote that his species concept excluded what was named C. infortunatum L. in P-JU. Two collections exist in Ventenat’s herbarium. A cultivated specimen from Cels’s garden and a second with two leaves with a label “Dedit Juss., exclusis syn. et figuris Rhumphii et Burmanii” and two additional leaves with a blank label attached. The two leaves “Dedit Juss.” clearly represent what Ventenat called C. infortunatum and should not be considered as type material of his C. viscosum . No further material has been located at P-JU. In spite of any additional information regarding the two leaves present on the sheet we prefer to consider this specimen [G00341644] as original material whereas the cultivated plant from Cels’s garden is designated here as the lectotype.
