Editorial Note
Treated by Bean under the synonym.
A shrub to 5 or 6 ft high, glabrous in all its parts. Leaves with two or three pairs of leaflets, which are lanceolate to oblong-ovate, bluntly pointed at the apex, 3⁄4 to 11⁄2 in. long; a characteristic gland is found on the main-stalk between the lowermost pair of leaflets. Flowers rich yellow, borne in late summer in clusters of three to eight at the ends of axillary shoots; corolla somewhat cup-shaped, about 1 in. wide.
A native of N. Argentina and neighbouring parts of S. America, introduced in 1796. It is best known as a shrub for the cool greenhouse but has been grown successfully outside in many mild gardens; even there it is best on a sunny wall, as it needs abundant sunshine if it is to flower well and ripen its wood. It should be spurred back in spring before growth commences and may be propagated by cuttings of half-ripened wood.
