Type (lectotype, designated here):— [ SPAIN], “ Cerdagne : Llivia et Villeneuve, coteaux, 1250-1400 m.”, 18 Jun. 1926, F. Sennen nº 5679 [Exssicata “Plantes d’Espagne”], MA barcode (MA72763!) ( Fig. 3 ); isolectotypes: BC barcodes ( BC983360 ! and BC983361 !), BCN (barcodes BCN 25145! (ex BCF]) and BCN 25146!

– L. collinum Gussone (1844: 808) , nom. inval., nom. prov. (ICN Art. 36.1)

Note:— Gussone (1844: 808) included in “ Linum austriacum ” this comment: “Ic. Adenolinum austriacum. Reich. cent. 46 f. 5456. In descriptione lege: filamenta divergentia, stylis erectis albidis duplo breviora!, calycem aequantia, basi coerulescentia; antheris viridulis. In planta sicula folia omnia pellucido-punctata et tuberculata, multo angustiora ac tenuiora (nam fere filiformia), quam in planta austriaca; sepalcrum nervus medius non usque ad apicem productus ut in icone citata, sed usque ad medium ut in icone L. squamulosi Reich. l. c. f S5456 b; ita ut inter utrasque species media, ac forsan nova, et tunc L. collinum appellanda”. Therefore, according to Art. 36.1 of the ICN ( Turland et al. 2018) the name “ Linum collinum ” indicated by Gussone (1844: 808) is not validly published because it is merely proposed as a provisional name.

Type designation of Linum immaculatae : :— The name Linum immaculatae Sennen (1926 : exssicatum nº 5679) was mentioned by Sennen (1927: 636) and described in the Sennen’s exsiccata “Plantes d’Espagne” with the number 5679 in a printed label. There are several specimens belonging to this exssicatum nº 5679 (e.g., barcodes PH 00015290, MA471208, MA72763, MAF59987, BCN 25145 (ex BCF), BCN 25146 (ex BCC), BC983360 , BC983361 ). In these herbarium sheets, the original printed label includes the name “ Linum Immaculatae Sennen / gr. alpinum ”, the provenance “Cerdagne: Llivia et Villeneuve, coteaux, 1250-1400 m.”, the date “18-VI [1926]”, a complete description of this species “NOTE.- Souche et racine épaisses-ligneuses; tiges longues-nombreuses-ascendantes-ramifiéeslaxifoliées; feuilles linéaires devenant obscures, un peu élargies sous l’inflorescence allongée-laxiflore; pédicelles longs arqués-divergents, atteignant 15 mill.; sepals largement elliptiques, obtus, à mucron oblique et à sommet énervulé; petals d’un très beau bleu, grands, 15 mill. et plus; capsule très exerte-mucronulée, 7 × 5 mill.; grains de silhouette étroite-oblongue, bien marginées”, and the comment “Dévote dédicace de ce bel endémisme à l’Immaculée”.

All the sheets bears complete and well-developed material. We designate the specimen at MA (with barcode MA72763) as the lectotype of Linum immaculatae ( Fig. 3 ).
