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.
