Liscione, Speciale (sec. Cottin 2002)
Citrus x limon (L.) Osbeck, pro sp. (sensu Mabberley 1997, Bayer et al. 2009); Citrus limon (L.) Burm. f. [=Citrus x limon (L.) Osbeck, pro sp.] (sensu Swingle and Reece 1967)
Crown compact or dense, not weeping. First-year twig surface glabrous; second- or third-year twig surface striate; thorns absent or not persistent; prickles absent or not persistent. Petiole glabrous, length short; wings absent. Leaflets one, margin bluntly toothed, shade leaflet blades flat or weakly conduplicate, sun leaflet blades weakly conduplicate. Scent of crushed leaflets freshly lemon-like. Fruit as broad as long or longer than broad; rind green-yellow (6), yellow (7-10), or yellow-orange (11); rind texture slightly rough (4-5); firmness leathery; navel absent; flesh yellow; taste sour.
Hodgson (1967) provided the following additional notes on the cultivar:
"Fruit large, oblong-cylindrical; collared or short-necked; truncate at apex; prominent sharp-pointed conical nipple surrounded by pronounced areolar furrow, commonly deeper on one side; seeds very few. Color yellow at maturity. Rind thin, very smooth, shining; tightly adherent. Segments 8 to 9; axis medium-small and solid. Flesh color greenish-yellow; crisp and juicy; flavor highly acid with slight bitterness. Crop produced mainly in fall and early winter. Earliest of Italian varieties.
Tree vigorous, upright-spreading, usually thornless; foliage moderately dense. Leaves large and somewhat citron-like, with round-pointed blades, undulate margins, and short wingless petioles. Moderately productive but does not respond well to forcing treatment and hence grown primarily for early fruit."
