Hardenbergia
(named in honour of the Countess of Hardenberg, sister to Baron Huegel, the celebrated traveller). ORD. Leguminosae. A small genus (three species have been described) of greenhouse, glabrous, twining herbs or under-shrubs, limited to Australia. Flowers violet, white, or pinkish, with a yellowish or greenish spot on the standard; in axillary racemes. Leaves of one, three, or five entire stipelate leaflets. The species succeed in a compost of two parts peat and one loam, with the addition of a little sand and charcoal, to keep the soil open. Propagated by seeds, or by cuttings, made of firm young side shoots in April, inserted under a bell glass, and placed in a warm frame or pit, without bottom heat. Hardenbergias are well adapted for planting out, and training up rafters in a greenhouse, where there is a little shade in summer, and a temperature of 40 deg. to 45 deg. in winter. H. Comptoniana (Compton's).* fl. closely resembling those of H. monophylla in size, colour, and structure; in pairs or clusters of three or four along the racemes. March. l., leaflets three or five, varying from ovate to linear-lanceolate, rather obtuse. rounded or truncate at the base. 1803. SYNS. H. digitata (B. R. 1840, t. 60), H. Huegelii, H. Lindleyi, H. Makoyana, Glycine Comptoniana (A. B. R. 602; B. R. 298), Kennedya macrophylla (B. R. 1862).

H. monophylla (one-leaved).* fl. purple, usually numerous, in pairs or rarely three together, the upper racemes often forming a terminal panicle. April. l., leaflets always solitary, usually ovate or lanceolate, more or less cordate or rounded at the base, often coriaceous and strongly reticulate, but varying from broadly cordate-ovate to narrow-lanceolate. 1790.
