Narcissus nevadensis subsp. herrerae Algarra, Blanca, Cueto & J. Fuentes View in CoL subsp. nov. ( Figure 1 View FIGURE 1 ).
Type:— SPAIN. Granada: Jayena, Sierra de Almijara , bco. de la Culebra, 30SVF 2781, 1070 m elevation, 09 April 2016, peat-like pastures over dolomitic limestone, G. Blanca & J. Fuentes (holotype: GDA 62658 About GDA !; isotypes: GDA 62657 About GDA !, MA!, MGC!, COA!, SEV!) .
Description: — Leaves longer than scape, 2-keeled; scape thickness 5–8 (–9) mm, with section angular 2-edged, with several smaller supplementary keels; spathe 33–71 mm long; solitary flowers or in umbels of 2–3 (–4); pedicels 40–64 mm; tepals and corona usually concolorous; corona 19–30 mm long, crenate-toothed.
Eponymy: — The subespecific epithet honours Dr. Carlos M. Herrera, who made molecular studies of daffodils from N. sect. Pseudonarcissus in southern Spain, and encouraged our study.
Habitat and distribution: — Narcissus nevadensis subsp. herrerae is known so far from a mountainous area of southern Spain, within the “Natural Park of Sierras de Tejeda, Almijara y Alhama”, in SW Granada province ( Fig. 2 View FIGURE 2 ), between 980 and 1400 m elevation. It grows in riparian hygrophilous communities which are usually degraded by fireprevention treatments and by frequent uprooting by storms, together with Erica erigena R. Ross in Dandy (1969: 164), Rubus ulmifolius Schott (1818: 821) , and Scirpoides holoschoenus (Linnaeus 1753: 49) Soják (1972: 127) .
Phenology: — Flowering in March to April, and fruiting in June.
Conservation status:— The newly described subspecies is a narrow endemic of Sierra de Almijara, in southwestern Granada province. For this reason, legal and management conservation measures are needed. According to the IUCN (2012) categories, here we consider N. nevadensis subsp. herrerae as Endangered (EN) based on criteria A4, and B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v). It is recommended to increase the vigilance in the headwaters of the rivers to avoid improper forest work and uncontrolled water abstraction ( Table 2).
Taxonomic relationships: — According to the genetic analyses on N. sect. Pseudonarcissus ( Jiménez et al. 2009, Medrano et al. 2014, Marques et al. 2017), the taxonomic treatment of the section in previous publications ( Zonneveld 2008, Navarro 2011), shows a distinction of species that appears to be more consistent than the more recent proposal in Flora iberica (cf. Aedo 2013), whereby all the trumpet daffodils from the Baetic and sub-Baetic ranges are assigned to a single taxonomic entity, N. pseudonarcissus subsp. nevadensis . The results of our morphological study ( Tab. 2) show that three morphologically distinct entities can be distinguished, which have discontinuous distribution areas, and which deserve recognition at subspecific rank. This treatment is coherent with a previous phylogenetic analysis showing three genetically distinct groups with very strong bootstrap support (cf. Medrano et al. 2014).
The new arrangement we propose here for that complex includes three allopatric taxa ( Fig. 2 View FIGURE 2 ). First, the newly described Narcissus nevadensis subsp. herrerae is restricted to the Natural Park of Sierras de Tejeda, Almijara y Alhama (SW Granada province). Secondly, N. nevadensis subsp. nevadensis occurs only in Sierra Nevada National Park, Sierra de Baza Natural Park, and in Sierra de los Filabres ( Granada and Almería provinces). Finally, N. nevadensis subsp. longispathus is taxonomically the most complex subspecies and shows a broader distribution; its area extends through the Natural Park of Sierras de Cazorla, Segura y las Villas, where the type locality is placed (Jaén and Albacete provinces); the Natural Park of Sierra de Castril (Jaén province plus adjacent NE areas of Granada province); some neighbouring areas of the provinces of Murcia and Albacete; and one disjunct location in Cuenca province (cited there as subsp. nevadensis by García Cardo 2014). It is worth mentioning that this subspecies has often been accepted at species rank as N. longispathus Degen & Hervier ex Pugley (1933: 54) , and even some of its populations had been recently described also as independent species, namely N. segurensis S. Ríos et al. (1999: 155) and N. yepesii S. Ríos et al. (1999: 161) , both from Sierra de Segura (Albacete province), N. alcaracensis S. Ríos et al. (1999: 160) from Sierra de Alcaraz (Albacete province), and N. enemeritoi (Sánchez-Gómez et al. 1998: 63) Sánchez-Gómez et al. (2000: 430) from Sierra de Moratalla (Murcia province). However, the reliability of these four latter species was not upheld by subsequent molecular ( Medrano & Herrera 2008, Zonneveld 2008, Jiménez et al. 2009) and taxonomic works ( Navarro 2011), and accordingly they are synonymised here to a widely recircumscribed N. nevadensis subsp. longispathus , a combination that we establish here.
