Adiantum truncatum Burm. f., Fl. Ind.: 235, tab. 66, fig. 4. 1768.

≡ Acacia truncata (Burm. f.) Hoffmanns., Verz. Pfl.-Kult.: 34. 1824. (Leguminosae)

Lectotypus (designated here): [AUSTRALIA]: Burm. f., Fl. Ind.: tab. 66, fig. 4. 1768 (Fig. 1).

Notes. – Adiantum truncatum was described based on a sterile Christiaan Kleynhoff collection. This name is currently accepted under Acacia truncata (Leguminosae) . The Kleynhoff collection was cited as originating from Java but this is certainly an error as this plant does not grow in Java (MERRILL, 1921: 353) but is rather endemic to southwestern Australia (MASLIN, 1978, 2001).

Despite another thorough search in the Geneva herbarium, no original material was located, as already mentioned by MASLIN (1978: 318). We therefore formally designate the plate in Flora Indica as lectotype.
