(2970) Proposal to conserve the name <i>Agrostis lazica</i> (<i>Poaceae</i>) with a conserved type

(2970) Agrostis lazica Balansa in Bull. Soc. Bot. France 21: 12. Mai (sero)–Jun (prim.) 1874 [Angiosp: Gram.], nom. cons. prop. Typus: “[TURKEY, Rize prov.], Khabakhar [Kabakçur, Gölyayla] (Lazistan), 2500 m, 1 Sep 1866, Pl. Or.

Orient. 5: 522. 1884) are two relatively widespread species distributed Russian Caucasus Southwest Asia subalpine alpine zones (Ivanov, Consp. Caucasi Rossicae: 31. 2019). Although similar morphologically, they clearly distinct from one another. is distinguished by the ratio callus hairs to lemma length (0.06–0.24 vs. 0.40–0.64) (0.1–0.4 0.8–1.4 mm). Rarely, can be hairless lazica. seems an example a grass defined too broadly at time description on basis morphological criteria. The original (Balansa, l.c.) covers least species: s.str. balansae. It contains no distinctive traits these species, just general characteristic awn, which we have translated French as: “usually inserted below middle strongly exceeding it geniculate slightly twisted lower part”, also that “its glabrous or hairy” “the palea half lemma”, could match either species. (l.c.) recognized three varieties under lazica: “var. genuina” (not validly published according Art. 24.3 ICN), var. major minor Balansa, all apparently represented same exsiccate series. Balansa's concept within poorly his protologue based very few characters related rather with plant habit, not suitable for use classification. descriptions do meet requirements (Art. 38.1 38.2 Note 2) (even if inadequate distinguishing taxa named). (l.c.), lazica, cited own number initial identification (“Bal. Exsicc. No. sub Agr. canina L.”), but did specify herbarium, thus indicating specimens series as syntypes 40 ICN, Turland al. Regnum Veg. 159. 2018). Twenty-six duplicate sheets this been located them were collected September 1866 elevation m northern slope Pontic Mts. Province Turkey. Detailed examination 26 revealed heterogeneous mixture different (G00195232, G00195233, G00330354, G00784775, JE00028958, K000838089, L.1207466, L.1207469, L.1207474, P02255414, P02333024, P02333025, P02333026, W0007153, W18890096408), (G00784334, L.1207471, P02255601, balansae]) planifolia K.

There was confusion about application names until Probatova (Zlaki Rossii: 247. 2019) unintentionally selected G00195232 (G) lectotype satisfying 7.11 ICN. Based type conclude represents basionym: Boiss. lectotypified G00330354 (G-BOIS) (l.c.). This revelation results following nomenclatural changes: (1) known “Agrostis lazica” requires name; none currently available taxon. (2) Because predates taxon epithet “balansae” Calamagrostis/Penthaterum/Agrostis (e.g., Boissier, l.c: 522; 1928: 82; Roshevitz 197. 1939: 190; 1976: 335; 76; l.c.; Doğan, l.c.: 353; Kolakovskij, Abchasia, 4: 165. 1986; 96; 2006: 305; Nersesian, 214; 693; Probatova, would get “lazica”, becoming Balansa. synonym Admittedly, there nothing incorrect typification conflicts protologue; only failure over years look at, interpret, realize identity material. Our solution case propose conservation conserved 14.9 ICN since cannot superseded 9.19(c) because part therefore serious conflict (see 9 7 ICN). Specimen L.1207471 corresponds traditional usage “lazica”. proposed will resolve situation rare widely accepted does any legitimate persisting taxonomic inconsistency, when synonymization led some misinterpret If proposal accepted, well-established abandoned required Asian populations treated further inflate already huge synonymy nomenclaturally taxonomically difficult genus Agrostis.
