Ra dix parva, fibrosa, annua (?),.
Gaules vageramosi. Rami diffusi, procumbentes, flex-

Folia sublonge petiolata, duo summa opposita, petiolis
brevibus. Foliola oblongo-obovata, sub lente (ut

globosam, demum ovatam dense congesti..
Calyx {Jig.-1.) tubulosus, pilosus, lineis elevatis nota-

Corolla calyce longior, pallide purpurea, subasqualis.
Vexillum lineari-oblonguin, dorso convexo. A te

Root small, fibrous, annual (?).
Stems irrregularly branched. Branches diffuse, procumbent,
flexüose, striated, clothed with short hairs.
Leaves on rather long footstalks, the two uppermost opposite
with short footstalks. Leaflets oblongo-
obovate, undpr the microscope (as well as the
footstalk) pilose, scarcely serrulate, deep green;
the superior ones frequently shortly apiculated,
the inferior smaller, obcordate.
Stipules lanceolate, acuminate, striated, pilose.
Flowers thickly collected together into a pedunculated,
terminal, solitary, globose, at length ovate spike.
Calyx (fig. 1.) tubulose, pilose, marked with elevated
lines, quiuque-dentate, with the teeth nearly equal
in length, straight, at length after flowering elongated,
unequal and remarkably patent, (fig . 2.)
Corolla longer than the calyx, pale' purple, nearly
equal. Vexillum linear-oblong, convex on the
back. Wings gibbose near the middle on the superior
margin. Keel much compressed.
Pericarp : A roundish compressed legume, terminated
by the filiform style, two-seeded, (fig. 6.)
Seed rounded, approaching to reniform, pale brown.

I n Britain this Trefoil is not uncommon in salt marshes, flowering in the summer months: but on the continent
of Europe it does not seem to be at all known, unless the Trifolium irregulare of Pourret, in the Transactions
of the Academy of Thoulouse, and of Decandolle, as quoted above, should prove to be the same. The description
of die latter author agrees indeed perfectly with our specimens, which were gathered near Yarmouth, except when,
the calyx is said to be shorter than the flower, and to be hairy only a t the summit of the tube, bmith calls the ca-
lycine teeth “ foliaceous but this is hardly the case, though they become enlarged after flowering and singularly
patent, whence Ray has given it the name of the Star, or Teasel-headed Trefoil. TT .
We have no species with which T. maritimum is likely to be confounded ; and it is extraordinary that Hudson
should not have distinguished it (in the second edition of his Flora) from T . stellatum,, which is a very different
