21. Squilla Steinh. View in CoL View at ENA

in Ann. Sci. Nat. Bot. sér. 2, 6: 276 (1836),

Typus generis:— S. maritima View in CoL (L.) Steinh. (lectotype, vide Pfeiffer, Nom. 2(2): 1252. 1874).

Charybdis Speta View in CoL in Phyton (Horn, Austria) 38(1): 58 (1998), nom. nov. et nom. illeg. superfl. [Art. 52 of the ICN] ( Figs 52–54 View FIGURE 52 View FIGURE 53 View FIGURE 54 ). Typus generis:— C. maritima View in CoL (L.) Speta (holotype).

Description:—Usually tall bulbous geophyte. Bulb usually large and hypogeal, rarely somewhat epigeal, ovoid to globose, up to 20 cm in diam. Roots thickened and branched. Leaves (4–)6‒10 per bulb, narrowly lanceolate to widely ovate, hysteranthous, up to 35 cm long, margin entire or sometimes undulate with ciliae or minute papillae, green or somewhat glaucous, smooth, glabrous. Inflorescence a long, erect, multiflowered raceme, with up to 1000 flowers, 6‒70 cm long; peduncle 15‒120 cm long, dull green with grey to purple tinge, terete, erect, smooth and glabrous; pedicels 5‒35 mm long, subpatent and usually arching upwards, sometimes erect or patent at anthesis. Bracts narrowly lanceolate, usually dry and wrinkled at flowering time, lowermost with short spur; bracteoles present and distinct. Flowers stellate or with reflexed lobes, erect-patent, diurnal, lasting more than one day. Tepals 6, biseriate, 7‒16 mm long, free or connate for less than 1‒2 mm, lanceolate-ovate to spathulate, usually white or rarely purple, with purplish or green longitudinal band. Stamens 6, spreading; filaments smooth, usually white and lanceolate to narrowly triangular, flattened or rarely filiform and purplish; anthers dorsifixed. Ovary ovate-oblong, usually with three apical protuberances, green to yellow, with ca. 5‒10 ovules per locule. Style 3‒12 mm long, erect, white or rarely tinged with purple, with trigonous stigma. Capsule ovate, 7‒19 mm long, green first and yellowish and papyraceous after ripening, valves completely dehiscing from base, tepals cohering and inrolled above ovary after anthesis, circumcissile from base and persisting as a cap at the top of the developing capsules. Seeds ovate-oblong to linear-oblong, 4‒12 mm long, flattened, testa black, with sinuous anticlinal cell walls.

Number of species and distribution:— Squilla includes twelve species, occurring mostly along the Mediterranean Basin, spanning the Canary Islands and the Middle East ( Speta 1998a, Martínez-Azorín et al. 2022) ( Fig. 49 View FIGURE 49 ); it is nearly restricted to the Mediterranean and Macaronesian Regions (sensu Takhtajan 1986). For further information on Squilla see Pfosser & Speta (2001, 2004), Crespo et al. (2020), and Martínez-Azorín et al. (2022).

Karyology:—2n=20 ( Martinoli 1954, Battaglia 1957, Bartolo et al. 1984, as Urginea undulata (Desf.) Steinh. ; Valdés-Bermejo 1980, Battaglia 1957, as D. maura Maire ); 2n=28 ( Bramwell et al. 1972, as Urginea hesperia Webb. & Berth. ); 2n=40 ( Satô 1942, as Urginea scilla Steinh. ); 2n=20, 30, 40, 50, 60 ( Battaglia 1957, 1964, Valdés-Bermejo 1980, Speta 1980, Pfosser & Speta 2001, Rico 2013, Bacchetta et al. 2012); 2n=20, 40, 60, 60+1B, 60+2B ( Boscaiu et al. 2001, Fernández et al. 2001, Talavera et al. 1995, Oberprieler & Vogt 1994, as Urginea maritima ).

History, diagnostic characters, and taxonomic relationships:— Martínez-Azorín & Crespo (2016a) showed that the Linnaean Scilla was first typified on Scilla maritima Linnaeus (1753: 308) by Rafinesque (1837: 8) and not on Scilla bifolia Linnaeus (1753: 309) as usually accepted [vide Index Nominum Genericorum: Farr & Zijlstra (2023) http://botany.si.edu/ing/].

Steinheil (1836) described Squilla to segregate Scilla maritima Linnaeus (1753: 308) ( Urginea scilla Steinheil 1834: 321 ) from his previously described Urginea , implying Squilla to be different from the name Scilla . Speta (1998b) accepted separation of both Urginea Steinh. and Squilla , but proposed the new name Charybdis , with C. maritima ( Linnaeus 1753: 38) Speta (1998b: 60) as type, to replace Squilla since he considered the latter to be an orthographic variant of both Scilla and Skilla Rafinesque (1837: 13) , and therefore a later illegitimate homonym. However, based on the typification by Rafinesque (1837) of Scilla maritima , Charybdis is illegitimate under Art. 52 of the Shenzhen Code as it was superfluous when published, a fact that makes Charybdis unavailable for use.

Martínez-Azorín & Crespo (2016b) requested the Nomenclature Committee for Vascular Plants (NCVP) for a binding decision on whether Scilla L. (subfam. Hyacinthoideae ) and Squilla Steinh. (subfam. Urgineoideae Asparagaceae subfam. Scilloideae trib. Urgineeae ) are sufficiently alike to be considered orthographic variants and to be confused. After several attempts, a sufficient number of the Committee Members voted recently in favour of a binding decision that both names are not confusable (cf. Appelquist 2022), which deed allows Squilla to be used in the sense of the current concept of Charybdis ( Martínez-Azorín et al. 2022) .

Previous phylogenetic analyses ( Pfosser & Speta 2001, 2004, Manning et al. 2004, Pfosser et al. 2012) show samples of Squilla (as Charybdis ) forming a strongly supported clade. Many authors recently accepted Charybdis as distinct from Urginea and Drimia at generic rank (cf. Speta 1998b, Pfosser & Speta 2001, 2004, Conti et al. 2005, Jeanmonod & Gamisans 2007, Bacchetta et al. 2012, Ali et al. 2013, Véla et al. 2016), although others (e.g. Manning et al. 2004, Manning & Goldblatt 2018, WCSP 2021) place them in an expanded and broadly circumscribed Drimia . The phylogenetic analyses of Martínez-Azorín et al. (2023a) included 22 samples of Squilla , which formed a strongly supported clade in an isolated position within Urgineoideae . Therefore, based on the distinct morphology and genetic divergence of these plants, we here accept Squilla following Martínez-Azorín et al. (2022), which is mostly restricted to the Mediterranean Basin.

Epitype (designated by Martínez-Azorín et al. 2022):— PORTUGAL. Sierra de Monsanto, environs de Lisbonne, pentes pierreuses, July−August 1877, J. Daveau (P02166423! epi.; P02166260!, P02166417!, P01811235!, P01811236!, isoepi.).

Comments on typification:—Recently, Martínez-Azorín et al. (2022) considered that the lectotype of Scilla maritima , first designated by Ferrer-Gallego (2013: 40) on the voucher L0052807, should be disregarded according to Art. 8.2 of the ICN, because completely developed adult leaves in this species are never coetaneous with flowers at anthesis in a given population. This implies that the “ lectotype ” selected by Ferrer-Gallego (2013) includes two specimens collected at different times: i) leaves, and ii) the flowering scape. Considering Ferrer-Gallegos’s (2022) reaction to our lectotypification, and in the light of the recentmost proposal by Mosyakin & McNeill (2022) to amend Art. 8, after which the information in the protologue will rule, we still consider that the voucher L0052807 cannot be a proper lectotype, following Linnaeus’s statement in Hortus Cliffortianus (1738: 123) that is cited in the Scilla maritima protologue of 1753: “ Scilla radice tunicata [….] Singulare est quod foliis destitute floreat.” Further, Clusius (1601: 171), which is also cited in the protologue of S. maritima , illustrated the species through both a bulb with fully-developed leaves (winterspring facies) and two bulbs with flowering and fruiting scapes; those latter figures are completely lacking leaves (later summerearly autumn facies); in addition, Clusius (1601) describes the typical hysteranthous behaviour of the species in Hispania as follows: “Copiose nascitur supra Olysipponem & plerisque aliis Lusitaniae & Hispaniae locis. Floret Augusto & Septembri, semen Octobri & Novembri maturescit; folia maturo jam semine, & exarido caule, emergunt Novembri & Decembri.” Based on those facts, we do believe that Linnaeus never saw plants of Scilla maritima showing flowers and leaves coetaneously, as he indirectly claimed in his Hortus Cliffortianus ( Linnaeus 1738), and hence the Linnaean voucher L0052807 most likely represents a “collage” of mixed gatherings of flowers and leaves collected at different times, and it as a whole cannot be eligible as lectotype. Therefore, the lectotype and epitype we designated ( Martínez-Azorín et al. 2022) are considered here as appropriate to preserve the currently most widely accepted concept of this species.
