G. s! Gibson, W. W. Newbould and C. C. Babington, in
the sandy district near Thetford, July 28, 1848, and was
afterwards noticed, Aug. 2, 1848, by the present writer, near
Cambridge. Mr. G. S. Gibson is believed to have since
found it near Saffron Walden, Essex. It is easily recognised
if attention be paid to the relative length of the petals and the
shape of the ripe pod.
Root fusiform, biennial. Stem branching from near its
base, a foot to a foot and a half in height, ascending, glabrous.
Stipules subulate, entire. Leaves ternate, on short channeled
stalks; leaflets of the lower leaves obcordate or obovate-
oblong; of the upper gradually narrower and smaller; all
unequally but finely serrate. Raceme long, slender, lax; its
central stalk finely hairy. Pedicels very short, arcuate,
slightly hairy. Bracts subulate, rather hairy, as long as the
pedicels. Calyx glabrous; its teeth broadly subulate, shorter
than the tube, slightly hairy. Corolla yellow. Standard as
long as the wings, longer than the keel. Pod oblong, blunt,
mucronate, transversely rugose-plicate, glabrous, rounded, but
with a strong prominent rib both above and below, brown.
Seeds oblong, not compressed; hilum forming a slight notch,
not a deep hollow.
Much difference of opinion has been expressed about the
name rightly belonging to this plant. Koch has recently been
led to suppose it the typical Trifolium Melilotus officinalis,
Linn. (Fl.Susc. ed. 2.258),but Fries [Summa, 163,) conclusively
shows that the Linnaean plant is what Persoon and Koch have
called M. macrorhiza, and most other botanists, including
those of Britain, have denominated Trifolium officinale, or
Melilotus officinalis. M. Petitpierreana of Willdenow is a
white variety of this species which has not as yet been found
in Britain.
Our figure is taken from specimens gathered near Cambridge,
on Aug. 2, 1848.'—C. C. B.
