Rotala illecebroides (Arnott) Koehne (1880: 161)

Lectotype (Step I: Vide Cook (1979: 72); Step II designated here):— INDIA. Peninsular India Orientalis, Herb. Wight Propr. 2317 (K, K000729643!, isolectotypes: Herb. Wight Propr. 2317 K, K000729644!, E, E00174996!, E00179144!, G, G00227385!).

Notes: —Arnott proposed the name Ammannia illecerbroides (mss) using Wight’s collection (Wight 2713), based on which Koehne (1880) published the name R. illecebroides . In 1979, Cook designated the Herb. Wight Propr. 2713 as a type for the name, citing the following information: “Type: India, “Peninsula Ind. Orientalis”, Herb. Wight propr. No. 2317 (holotype: K; isotype: K, G)”. This constitute the first step lectotypification. At K, we were able to track down two specimens of HWP 2317 (K000729643! and K000729644!). As per Art. 9.3 and 9.17 of ICN (Turland et al. 2018), we have designated HWP no. 2317, K000729643! as the lectotype which constitute the second step lectotypification.
