.A. NATIVE of dry barren and sandy pastures, flowering in
June, and known from several species of Trefoil, which otherwise
resemble it, by its downy softness to the touch.
Root annual, bearing small knotty swellings, such as we
have often mentioned in other diadelphous plants. Stems
procumbent, various in length and luxuriance, round,
branched, often zigzag, downy. Leaflets obovate, or ob-
cordate, finely toothed, downy. Stipulas ovate, broad,
pointed, somewhat membranous between the ribs. Heads
generally terminal, ovate. Calyx elliptical and swelling,
hairy, with ten deep furrows, and five green, tapering,
fringed teeth, lengthened out after flowering. Corolla of a
pale rose-colour, about as long as the calyx. Pod membranous,
with the rudiments of 2 seeds when young, one of
which only is ripened, and becomes thrice as large as that of
T. glomeratnm, t. 1063.
