232A87F8FFBEFFD95A3FE70A3026F836.taxon	discussion	NOTES Teucrium plectranthoides was described by Gamble (1924) based on specimens collected from the Western Ghats near Sengaltheri in Tirunelveli district, Tamil Nadu. There was no collection number mentioned in the protologue, and no holotype was designated. After an exhaustive search, one sheet at CAL [CAL 0000020524], five sheets at MH [MH 00002428, MH 00002429, MH 00002430, MH 00002431, MH 00002432], one at K [K 000821627], and one at NYBG [NY 0044453] were found. All eight sheets were annotated with the collection locality “ Sengalteri-Tinnevelly ”, with the collection date 25. Sep. 1916, and of a single gathering. However, the sheet found at K [K 000821627] is well preserved and has an additional label including the mounted parts of inflorescence, flowers, corolla, and calyx separately, with drawings of flower parts in Gamble’s hand. This specimen matches well with the description provided in the protologue. Therefore, the herbarium specimen K 000821627 is designated here as lectotype according to ICN Shenzhen code Article 9.12 (Turland et al. 2018).	en	Krishnaraj, Thittayil Puthusseri, Thomas, Alan, Sunojkumar, Purayidathkandy (2026): Lectotypification of three names of Teucrium L.

232A87F8FFBEFFD9585BE78736FBF836.taxon	discussion	NOTES Teucrium quadrifarium was first published in Prodromus Florae Nepalensis in 1825 by David Don. The author cited herbarium specimens of Hamilton and Wallich in the protologue, that were collected from Nepal. While searching for the herbarium specimens nine sheets were found, which are distributed in BM [BM 000521963], K [K 001114913, K 001114914, K 001114915, K 000821620], and E [E 00634434] and P [P 00686398, P 00686399, P 00686460]. The sheets deposited in K and E and P (except [P 00686460] are collected from Nepal bearing the Wallich catalogue number 2024.1. The herbarium specimen found at BM [BM 000521963], which was collected by Hamilton, is in accordance with the protologue and designated here as the lectotype of Teucrium quadrifarium according to Article 9.12 of ICN (Turland et al. 2018).	en	Krishnaraj, Thittayil Puthusseri, Thomas, Alan, Sunojkumar, Purayidathkandy (2026): Lectotypification of three names of Teucrium L.

232A87F8FFBEFFD958C6E3873738FB56.taxon	discussion	NOTES Teucrium wattii was described by Prain in 1890 based on specimens collected by George Watt with collection number 5127 from Manipur, Kassome summit region, and no holotype was designated. While searching for type specimens, six specimens collected by Watt were found in different herbaria. Of these, three sheets were deposited in CAL [CAL 0000020521, CAL 0000020522, CAL 0000020523], one each at K [K 000821628], G [G 00402072], E [E 00301966]. All the herbarium specimens are based on a single gathering with collection number 5127. The specimen atCAL [CAL 0000020523] is well preserved and matches well with the description provided in the protologue, and some fully opened corollas with stamens were also found well-mounted on the herbarium sheet. Additionally, a comparative illustration of the corolla of different Teucrium species is included. Therefore, the herbarium specimen CAL 0000020523 is designated here as the lectotype for the name Teucrium wattii Prain in accordance with Article 9.12 of ICN (Turland et al. 2018).	en	Krishnaraj, Thittayil Puthusseri, Thomas, Alan, Sunojkumar, Purayidathkandy (2026): Lectotypification of three names of Teucrium L.
