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.
