Ononis crassifolia Dufour ex Boissier (1840: 155)

Boissier’s protologue (1840: 155) of Ononis crassifolia , numbered “441” in the Voyage botanique dans le midi de l’Espagne, consists of a name “ Ononis crassifolia Dufour. ” followed by three synonyms: 1) “ Ononis tridentata β canescens. DC. Prod.” cited from Candolle (1825: 161), 2) “Anonis Hispanica frutescens foliis crithmi chrysanthemi Tourn. Herb.” cited from Tournefort (1719: 408), and 3) “Cicer montanum fruticans angustifolium serratum minus Barrel. Ic, tab. 419” cited from Barrelier (1714: t. 419). The protologue also includes the provenance “In collibus argillosis et salsis regionis montanae inferioris, circa Cacin et la Mala prov. Granatensis. Alt. 2500’-3000’. Fl. Jun. Jul. / Hab. in Hispaniâ praecipuè interior, regno Granatensi, Valentino (Cav.), Castellâ nova prope Cuenca (Quer), Aragoniâ (Asso), Catalauniâ (Quer)”, and followed by a complete description in French “Je ne sais si cette espèce est ou n’est pas une variété de l’ O. tridentata L.-Ic. Cav. tab. 152, que je n’ai jamais vue et qui se distingue par des feuilles linéaires entières ou tridentées à l’extrémité; mais ces plantes, dissent-elles être réunies, ce qui n’est point prouvé, le nom de Linné devrait être rejeté comme ne pouvant s’appliquer à la forme que nous décrivons et qui est de beaucoup la plus commue. L’ O. crassifolia forme des arbrisseaux de deux à quatre pieds de haut couverts d’un duvet blanchâtre, les feuilles sont épaisses, charnues, caduques, cassantes et glauques comme celles de l’ H. squamatum , de certains Atriplex et d’autres plantes particulières aux terrains argileux à sources salées, ells sont obovées et munies de six à huit petites dents ou crénelures peu prononcées et toutes égales entre elles; les fleurs sont roses avec l’extrémité de la carène plus forncée, les legumes sont velus, ovales, atténués par les deux estrémités, et deux fois plus longs que le calice”.

This name was not typified by Burdet et al. (1988). On the other hand, Devesa & López González (1997: 258) mentioned “Material original: G., herb. Boissier [n.v.]”. However, this statement cannot be considered as an effective typification according to Art. 7.11 of the ICN because the citation does not include the term “ type ” (typus) or an equivalent.

Among the original elements used by Boissier to describe his Ononis crassifolia , the references of Barrelier (1714: t. 419) provided an illustration that can be considered an original element. In addition, there is a gathering of Boissier with material collected “in salsis et collibus argillosis La Mala” [La Malahá] in July 1837, with several specimens preserved at M, MEL, and P (see below). These all specimens are undoubtedly identifiable with the species to which the name Ononis crassifolia is generally applied (leaflets blade obovate-cuneate, less than six times longer than wider, with 3–9 teeth in the upper half, sepals entire, inflorescence peduncle shorter than 10 mm, usually with an inconspicuous arista, inflorescence 1–2-flowered and raceme-like). I designate as the lectotype of the name Ononis crassifolia a specimen of this gathering preserved at P, barcoded P03447750 ( Fig. 3 ). As mentioned above, a specimen of this gathering was selected as the epitype of O. tridentata by F̂rther (in Turland & Jarvis 1997: 478). Therefore, O. crassifolia is a heterotypic synonym of O. tridentata .

Ononis tridentata f. latifolia Lange (1865: 153)

The protologue of Ononis tridentata f. latifolia published by Lange (1865: 153) includes the epithet “3. latifolia ” followed by the synonyms “ O. crassifolia Duf. ined., Willk. l. c. ex p.; Barr. ic. 420; O. Barrelieri Duf. ex p.), a bief diagnosis “foliis late obovatis, 5–7-dentatis”, and two gatherings “Vidi specimina lecta ad la Mala pr. Granada (Boiss.)! la Armilla fl. granat. (P. del Campo)!”. The protologue includes the gathering of Boissier from “La Mala” (Granada, Spain). A specimen of this gathering was designated as the epitype of the name Ononis crassifolia (M [and in this work as a second-step epitypification with barcode M0232962]), the gathering bears also several duplicates or isoepitypes (see e.g., M0232961, MEL2471775, P03447783 [stem mounted on the right half of the sheet], P03447784 [two stems mounted on the upper left half of the sheet], P03447754, P03447785 [three stems mounted on the left half of the sheet], P03447669, P03447750). On the other hand, there are other relevant syntypes of the second gathering cited in the protologue from Armilla and collected by Pedro del Campo (e.g., COI00053682, LY0175028, MPU1207861, P03447766, P03447752, P03490744, P03079357, P02993329, VTA011733). These sheets bear a printed label annotated as: “Pedro del Campo, Pl. de la Prov. de Grenade, 1852. / Distr. par E. Bourgeau. / 33. Ononis crassifolia, L. Duf. / (Coss.) / Granada, plaine salée de Armilla. / 6 Juin. Among all this material, I designate the specimen with barcode P02993329 ( Fig. 4 ) as the lectotype of the name Ononis tridentata f. latifolia , the specimens at COI (barcode COI00053682), LY (barcode LY0175028), MPU (barcode MPU1207861), P (barcodes P03447766, P03447752, P03079357, and P03490744), and VTA (barcode VTA011733) are therefore isolectotypes.
