Turkey appears to be a center of diversity for the genus Tripleurospermum Sch. Bip. (Anthemideae, Asteraceae) with c. 32 species among the c. 40 accepted species in the genus. Two Boissier's names Chamaemelum conoclinium Boiss. & Balansa and Chamaemelum monticola Boiss. & A. Huet are lectotypified and discussed.

Introduction
The genus Tripleurospermum Sch. Bip. (Anthemideae, Asteraceae) comprises c. 40 species (Oberprieler et al., 2007). Turkey appears to be the foremost center of diversity of the genus, with c. 32 taxa.
The names Tripleurospermum conoclinium (Boiss. & Balansa) Hayek and T. monticola (Boiss. & A. Huet) Bornm. are lectotypified herein. These species were originally described by Boissier (1856: 27; 1859: 98) within the genus Chamaemelum Mill. from Turkey. Scans of the two lectotypes can be found in the CHG (2021) website.

Lectotypus (designated here): Turkey: “Yachamichlar – Keui, à 8 km au nord d'Ouchak (Phrygie)”, 22.VI.1857, Balansa 1279 (G-BOIS [G00743746] image!); isolecto-: G-BOIS [G00743752] image!, G [G00421036] image!, JE [JE00017342, JE00017343] images!, K [K000929400] image!, P [P00852191, P00852193] images!. Syntypus: Turkey: “Yaïla de Bozdagh”, 17.VII.1854, Balansa 30 (G-BOIS [G00743751] image!; isosyn-: G [G00421037] image!, BM [BM000945956-S] image!, JE [JE00017344] image!, K [K000929401, K000929402] images!, P [P00852182, P00852183, P00852192] images!, WAG [WAG0000618] image!).
Notes. – Boissier (1859: 98) listed two Balansa's collections in the protologue of the name Chamaemelum conoclinium, i.e., “Bozdagh dictis Bal. pl. exs. 1854” [Balansa 30] and “Phrygiae cl. Balansa 1857” [Balansa 1279]. A single specimen in G-BOIS [G00743746] bears a handwritten label with the field number 97 and identical information of Balansa 1279 but with the annotation “Chamaemelum conoclinium sp. nov.” handwritten by Boissier. As pointed out by Al-Shehbaz & Barriera (2019: 12), in Balansa's collections it was frequent that the specimens bearing original handwritten labels were provisionally identified with a number and the duplicates distributed in printed labels with a different number. Those two specimens do therefore represent duplicates of the same collection. G00743746 is designated here as the lectotype of C. conoclinium because of the original label and the overall good conditions of the specimen.
Tripleurospermum monticola (Boiss. & A. Huet) Bornm. in Repert. Spec. Nov. Regni Veg. Beih. 89(2): 337. 1944.
≡ Chamaemelum monticola Boiss. & A. Huet in Boiss., Diagn. Pl. Orient. ser 2, 3: 27. 1856.
Type: “Hab. in Armeniâ circâ Erzeroum Huet du Pavillon! Calvert!”.
Lectotypus (designated here): Turkey: “Erzeroum”, VII.1853, Huet du Pavillon s.n. (G-BOIS [G00764314] image!; isolecto-: K [K000929413, K000929414] images!). Syntypi: Turkey: “Erzeroum”, 1854, Calvert 30 (G-BOIS [G00764313] image!); “Erzeroum”, 1853, Calvert 311 (G-BOIS [G00764316] image!).
Notes. – Collections by Huet du Pavillon and Calvert were cited in the protologue of the name Chamaemelum monticola by Boissier (1856: 27). Three syntypes are deposited in G-BOIS: Calvert 30, 311 and Huet du Pavillon s.n. The latter specimen bears a label with Boissier's handwriting and is designated here as the lectotype of C. monticola. The lectotype is a 4-part specimen that unambiguously fits with the diagnostic morphological characters stated in the original description.
