Myosotis congesta Shuttleworth ex Albert & Reynier (1892: 202)

≡ Myosotis stricta Link (1819: 104) var. congesta Rouy (1908: 302) = Myosotis tubuliflora Murbeck (1901: 400) = Myosotis senneniana Maire (1933: 222) .

Type (lectotype, here designated):— France: Champs négligés mais humides entre Bormes et St. Claire (Var), 27 March 1863, Shuttleworth s.n. (LY0002896!, image available at https://explore.recolnat.org/search/botanique/simplequery=LY0002896) ( Fig.1 )

Iconographies available from literature:— Blaise (1970, p. 503); Valdeìs (2012, Lam. 121), Azzaro et al. (2021; Fig. 1 ).

Notes:—We traced two herbarium sheets (LY0732429 and LY0002896) in Rouy herbarium at LY that can be considered as original material.The labels bring the diagnosis that is completely in accordance with the protologue: “ Myosotis congesta Shuttl., Imprimis pro M. stricta Link lecta, a qua differ floribus minoribus (pedicellis gracilioribus) in apicem caulis congestis, spicatis et patentibus. A M. versicolori differ characteribus ablatis et corollis caeruleis”. However, only one specimen (LY0002896, see Fig. 1 ) brings two autograph labels handwritten by Shuttleworth, while the other one (LY0732429) brings a label with a different handwriting and probably is a duplicate. In addition, the specimen chosen as lectotype is in conformity with the current application of the name ( Valdeìs 2012, Selvi 2018). Previously, an attempt to designate the type was already done by Blaise (1970), who reported only “Types: îles d’Hyères, Herb. Rouy”. According to Art. 7.11 of the ICN, this typification is invalid, since the designation of a type must be clearly indicated by a direct citation of the specimen.
