Rotala macrandra Koehne (1880: 176)

Lectotype (designated here):—[illustration] Wight’s Icones Plantarum 1: t. 258. 1840.

Figure 7

Notes: — Cook (1979) designated the Wallich catalogue number 2095H (K) collection as a type based on Koehne’s (1903) reference to “Wahrscheinlich Nepal, Wallich no. 2095H.” However, Koehne (1880) did not cite any Wallich specimens in his protologue; instead, he stated “ As. Mons. Ind. Or., locis non indicates, mixta cum 28. ” Koehne (1880) also mentioned consulting Wight and Arnott 28 in the footnote. This indicates that Koehne later studied the Wallich’s specimen (2095H). Further R. macrandra is restricted to Peninsular India. We looked in herbaria where Wight’s collections are deposited, but we were unable to locate the specimen. Here, we designate Wight’s illustration provided in Icones Wight 1 t. 258, cited in the protologue, as the lectotype in accordance to Art. 9.3 ( Turland et al. 2018).
