These specimens exactly agree with those of Chili. The flowers are small, a little protruded beyond the
silky calyces, dark purple, pale at the tips. It is a small slender spreading plant. Stems a span long.
Stipules often ovate.

In many particulars this agrees with the preceding species, but it is, in every respect, a much larger and
stouter plant, apparently growing quite erect. The stipules are I of ' “oh in length, the capitula more
than an inch. The calyx is quite as long, or rather longer than the corollas, which latter appear to be of a
purple colour.

A slender, erect, annual plant, glabrous in every part. Corollas purple, apparently persistent, and becoming
scariose.

In size and general aspect this Trefoil accords with T . depauperatum, but there the involucre is obsolete
and truncate, here (comparatively) large and deeply lobed.
