rigid, suffruticose (or annual?) erect, glabrous, with slender, virgate branches; leaves narrow-linear, or subulate, mucronate, scattered, sub-erect, flattish, tapering at base; racemes terminal, elongate, many flowered, pedunculate, the flowers often secund; bracts deciduous, lanceolate, acute; pedicels clavate, much shorter than the flower; alæ obovate-elliptical, very blunt, ant. sepals oval, very obtuse; keel acute, amply crested, lateral petals broadly obovate; capsule obcordate, winged; seeds albo-tomentose. A slender, erect, suffruticose or perhaps annual or biennial plant, nearly agreeing with P. virgata in floral characters, but much smaller and less woody.—To my eyes this plant resembles the much-disputed figure in Burman (tab. 74. fig. 4.) on which DC. founds his P. Burmanni; but, without reference to De Candolle's Herbarium, it would be unsafe to quote the latter name.
