Gymnosporia emarginata (Willdenow) Thwaites (1864: 409)

≡ Celastrus emarginatus Willdenow (1798: 1128)

≡ Maytenus emarginatus (Willdenow) Ding Hou (1963: 241)

Lectotype (designated here):— INDIA, Tamil Nadu, Tranquebar , Klein, s.n. ( B, B-W 04752-02 0) ( Fig. 1 ); isolectotypes: [B, B-W 04752- 01 0; HAL, HAL0145906; LECB, LECB0001906].

Notes: In search of original material for Celastrus emarginatus from ‘ India orientali ’ we were able to locate two specimens in B (B-W 04752-01 0 & B-W 04752-02 0), and one each in HAL and LECB that qualify here as syntypes ( McNeill 2014). Jordaan & van Wyk (2003) pointed only the B specimen (Herb. Willdenow 4752) as a holotype, which is superseded here.

Both the specimens at B can be easily identifiable as Willdenow’s collection due to a “W.” mark at the bottom right corner of the sheets (Eckardt & Hiepko 1970), which was written by D.F.K. von Schlechtendal [pers. comm. Katharina Rabe , Botanical Garden and Botanical Museum, Berlin]. The specimen folder (B-W 04752-00 0) is labelled with similar details concordant with the protologue and the label inside of the specimen folder reads “Klein Ind. 1795. W” [“Klein” refers to the collector Johann Gottfried Klein, “Ind.” refers to the locality, India, and “1795” probably refers to the year when Willdenow obtained the specimen]. Klein was a missionary botanist who collected plants from the Tranquebar, southern India ( Burkill 1953). He used to send many of the plant materials collected from southern India and Sri Lanka to Willdenow at Berlin ( Stansfield 1957). The label also reads “Kattanschi Mullu” [probably wild thorny shrub in Tamil].

The specimens in HAL and LECB were found to be duplicates, which were received from Willdenow [pers. comm. Katharina Rabe, BGBM, Berlin ]. This could be seen on the left bottom corner label of HAL specimen (HAL0145906), which reads “ Celastrus emarginatus ” | “Indie orient” [ India oriental] | “W. det” [Willdenow determined]. LECB specimen (LECB0001096) has a similar label as in the preceding specimen. The specimen in B (B-W 04752-02 0) bears flowers as well as fruits and is designated here as lectotype.
