4. U. rupestris (Salisb.) Dandy in Riddelsd., Hedley & Price, Fl. Gloucestershire 611 (1948)

( U. pendulinus DC. , Cotyledon pendulina (DC.) Batt. ).

Stem 20-50 cm, erect. Basal leaves orbicular, peltate, concave above, sinuate-crenate; cauline leaves progressively smaller, mostly reniform, dentate, the uppermost sometimes linear. Bracts usually linear, about equalling the pedicels, but occasionally large and leaf-like. Pedicels 3-9 mm. Flowers 7-10 mm, tubular, usually pendent; raceme fairly dense, sometimes branched at the base, occupying more than half the stem. Sepals ovate, acuminate. Corolla whitish-green or strawcoloured, sometimes tinged with pink; tube about 4 times as long as the ovate, mucronate lobes. Carpels tapered to a fairly long style. S. & W. Europe, northwards to Scotland. Al Az BI Br?Bu Co Cr G a G r H b Hs It Ju Lu Sa Si?Tu. A very variable species; some of the variants resemble 3, 5 and 6 in single characters and have caused much confusion. The most distinct is U. neglectus (Coutinho) Rothm. & P. Silva , Agron. Lusit. 2: 88 (1940), from Portugal, S. Spain and Islas Baléares, which possibly deserves subspecific status. It is a robust plant, with basal leaves often cordate rather than peltate, and a narrow corolla approaching that of 5.
