Email: [email protected] ABSTRACT This paper points out the inadvertent lectotypifications of six names in Phyllanthaceae viz., Antidesma neurocarpum Miq., Antidesma sootepense Craib, Aporosa latifolia Thwaites, Leiocarpus fruticosus Blume, Sauropus garretti Craib and Sauropus rostratus Miq. that have been overlooked and re-lectofied. Of these, a second-step lectotype has been designated for the name Aporosa latifolia. KEYWORDS: Phyllanthaceae; Antidesma; Aporosa; Breynia; lectotypification. Introduction Lectotypifications Chakrabarty & Gangopadhyay (1993, 1996, 2000) under Art. 7.11 Antidesma neurocarpum Miq., Fl. Ned.

After two years, Schot (1995: 451) cited the type as: “Type: 2000: 36): Thailand, Chiengmai, Doi Sootep, 6 June 1909, A.F.G. Thwaites 3433 (holo BM; iso P).” Later Chakrabarty & Kerr 676 (CAL0000023313!; isolectotypes A00106195, Balakrishnan (2018: 85) accepted the lectotypification of BM000951348, K000061510, K000061511, images!). Residual Chakrabarty & Gangopadhyay (1993) but they overlooked that syntypes: Thailand, Chiengmai, Doi Sootep, 20 June 1909, A.F.G. there are two duplicates of the gathering Thwaites CP 3433 at K Kerr 676 A (BM000951349, K000061512, K000061513, images!). and therefore the designation by Chakrabarty & Gangopadhyay (1993) should be accepted as first-step lectotype, to be narrowed Note: Hoffmann (2006: 210) overlooked the inadvertent to a single specimen in a second-step lectotypification as per Art. lectotypification by Chakrabarty & Gangopadhyay (2000: 36) and 9.17 of the ICN. As regards the designation by Schot (1995), this re-lectotypified the name based on a specimen at K (K000061511: should also be accepted as an effective lectotypification (Art. 7.11 image!). of ICN) but it is antedated by the designation of Chakrabarty & Gangopadhyay (1993).

As regards the synonym Leiocarpus fruticosus, available name, Sauropus rostratus to Breynia. Miquel (1861: 447) Chakrabarty & Gangopadhyay (1993: 160) cited the type as: “Type: described the species on the basis of two collections by J.E.

Subsequently Schot (2004: 220) ad Pager-dewok, fructif. (T.).” Chakrabarty & Gangopadhyay (1996: designated the lectotype based on a collection of Blume at L 544) included two species in their list of “Type specimens of (Blume 2136, L0041510: image!) but again used the words Malesian species in CAL” viz. Sauropus calcareous M.R. Hend. “proposed here”, not in accordance with Art. 7.11. Chakrabarty & and S. rostratus Miq. and cited the type of the latter as: “Type: Balakrishnan (2018: 82), having failed to recognize the effective Sumatra, Paggerdewok, Lampongs,Teysmann HB 4316, acc. no. lectotypification by Chakrabarty & Gangopadhyay (2003), 401736.” Thus, they inadvertently but effectively lectotypified the redesignated the lectotype based on a Blume’s collection at L name S. rostratus in compliance with Art. 7.11 of the ICN. (Blume 2136, L0041510: image!). However, this lectotypification was overlooked by Welzen (2003: 370) who re-lectotypified the name with another collection of Aporosa latifolia Thwaites, Enum. Pl.
