A Swan River species of Dryandra, discovered by Mr. Drum-
mond, and reared in the Royal Gardens of Kew from seeds sent
by that indefatigable and most successful botanist. Our living
plants in the Proteaceous House only differ from dried ones in
having narrower leaves. It flowers in the spring months.
Descr. Our Plants are three feet high, erect, much branched;
the branches terete, the young ones downy. Leaves scattered,
rather distant, sessile, lanceolate, in our variety linear-lanceolate,
spreading and recurved, harsh and rigid, remotely sinuato-
dentate, the teeth broad, decurrent, tipped with a sharp spine or
mucro, and the leaf terminated by the same: the base is some-
times entire, sometimes almost pinnatifid with rather long spinous
teeth: the upper surface is indistinctly veined, dark green,
glabrous, the underside clothed with compact white down. The
capitula terminate short branches, and are surrounded, as it were,
august 1st, 1847.

by a rosule of spreading leaves. Involucre of many closely-imbri-
cated, mostly subulate scales, the outer ones shorter and broader,
and sometimes spinous at the margin; the inner ones longer
and narrower and ciliated at the tips. Florets numerous, the
segments of the perianth linear-spathulate, clothed with yellowish
silky hairs. Anthers sunk in the hollow of the spathulate apex.
Style longer than the flower, tipped with a rather small cylindrical
glabrous stigma.
