Vicia L. |
| V. canescens Lab., Icon. PL Syr. 1:17, t. 7 (1791). Map 59, p. 285. Sturdy perennial, 12-80 cm, erect or ascending, sparsely to very densely hairy, subcanescent to sericeous. Leaves with or without tendrils; leaflets 5-12-paired, 5-40 mm, elliptic to linear-lanceolate; stipules semi-hastate, entire. Racemes closely 3-18-flowered, long-peduncled. Flowers large, 17-25 mm, lilac, or violet-blue. Calyx 6-13 mm, scarcely gibbous, purplish, lowest tooth half as long as the tube to about as long. Style dorsally compressed. Legume oblong, 26-35 x7-ll mm, densely adpressed-villous, -pilose or -pubescent, or glabrous with ciliate sutures, several-seeded. V. canescens is treated here as a polytypic species, remarkable for the variation in the indumentum of its legumes, even within some of its subspecies. Subsp. serinica (Uechtr. & Huter) Davis, t is confined to Italy. 1. Plants adpressed-villous-tomentose, silvery; legume densely adpressed-villous: leaves with or without tendrils 2. Upper leaves with or without a short simple tendril; stipules 1-2 x as wide as the stem 3. Stems 25-35 cm: leaflets 10-40 mm, linear-oblong, mostly obtuse; racemes 6-10-flowered subsp. canescens 3. Stems 12-15 cm; leaflets 5-15 mm, elliptic-lanceolate, acute; racemes 3-5-flowered subsp. argaea 2. Upper leaves with a well-developed simple or 2-3-sect tendril; stipules narrower than the stem or as broad subsp. leucomalla 1. Plants pilose, greenish or canescent; legume densely adpressed-pilose, pubescent, or glabrous with ciliate sutures: leaves with tendrils 4. Stems 3.5-5 mm diam., stout, straight and fistulose: stipules 1-3 x as broad as stems subsp. latistipulata 4. Stems 1.5-3 mm diam., straight or flexuous, ± solid; stipules narrower than the stem or as broad 5. Leaflets all ± linear-lanceolate, those of the lower leaves less acute than those of the upper leaves; stems erect or ascending-erect; tendrils mostly simple subsp. gregaria 5. Leaflets of the lower leaves obovate-oblong, obtuse or retuse, shorter than those of the upper leaves which are elongate and acute; stems flexuous- erect; tendrils mostly 2-3-sect subsp. variegata *V. canescens Lab. subsp. serinica (Uechtr. & Huter) Davis, comb. et stat. nov. Syn: V. serinica Uechtr. & Huter in Öst. Bot..Zeitschr. 55:81 (1905). This S. Italian population fails well within the morphological range of V.canescens sensu lato as accepted here.
