If published, it would be no easy matter to recognise it from description alone. It is only by good figures, taken from perfect flowering specimens of the living plants that we can hope to make known the distinguishing feature of the individuals of this singular family. The present species is among the most beautiful, a free bloomer, and its blossoms are large and showy.
DESCR. Our plant is nearly a foot in height, about four inches broad, tapering upwards, from a nearly cylindrical base, hence somewhat conical, the summit being the narrowest part: it is furrowed throughout its length rather deeply and acutely, forming elevated, rather sharp ridges or angles, which are studded at short intervals by small, dense, cushion-like tufts of wool, bearing the cluster (about twelve in a cluster) of sharp needle-
