Other taxa in genus


    Two-valved fruit formed from a single carpel widely known as a ‘pod’ typical of most members of the legume family (Leguminosae). The word has come to be used as much for members of the family as for their distinctive fruits.
    Sharply pointed.
    Attached singly along the axis not in pairs or whorls.
    (pl. apices) Tip. apical At the apex.
    Situated in an axil.
    (pl. calyces) Outer whorl of the perianth. Composed of several sepals.
    The inner whorl of the perianth. Composed of free or united petals often showy.
    An elliptic solid.
    With an unbroken margin.
    Lacking hairs smooth. glabrescent Becoming hairless.
    (botanical) Contained within another part or organ.
    Not opening naturally; remaining closed at maturity. (Cf. dehiscent.)
    Flower-bearing part of a plant; arrangement of flowers on the floral axis.
    Lance-shaped; broadest in middle tapering to point.
    lateral pair
    (in Cupressaceae) The pair of lateral scale leaves. (Cf. facial pair.)
    Leaf-like segment of a compound leaf.
    Stalk of inflorescence.
    Unbranched inflorescence with flowers produced laterally usually with a pedicel. racemose In form of raceme.
    Inflorescence in which flowers sessile on the main axis.
    Generally an elongated structure arising from the ovary bearing the stigma at its tip.

    A bushy shrub up to 10 ft high, all the vegetative parts and the peduncles and calyces warty with small black glands; young shoots slender, white-downy, longitudinally ribbed. Leaves alternate, trifoliolate, on stalks 34 to 112 in. long; leaflets lanceolate, tapered to a long acute apex, rounded or wide-cuneate at the base, entire, deep green above, paler beneath, the terminal leaflet 138 to 3 in. long, 12 to 1 in. wide, on a stalk 38 to 58 in. long, the lateral pair rather smaller and more shortly stalked. Inflorescences axillary, more or less downy, the flowers densely crowded into a spike-like raceme 1 to 2 in. long (but up to almost 5 in. long on wild plants), borne on a peduncle 112 to 312 in. long (up to 6 in. long on wild plants); calyx deeply cup-shaped about 616 in. long, unequally divided to nearly half-way into five narrowly triangular, acute, erect lobes; corolla of the usual pea-flower form, petals white, the standard blotched with blue and the keel with a blue blotch on the lower surface; stamens and style included. Legume about 14 in. long and half as wide, oblong-ellipsoid, hairy, indehiscent, enclosed in the hard dry calyx and containing a single seed. Bot. Mag., t. 990.

    Native of Peru, where it was originally discovered, and of Chile; introduced, according to Aiton, around 1770. It is variable in the degree of hairiness, some Chilean specimens being more hairy than the cultivated plants and others almost glabrous, while a Peruvian specimen has the stems, petioles, inflorescence axes, and calyces densely white villose.

    Probably all the plants now cultivated in Britain derive from Harold Comber’s introduction from Chile in 1926 (C.572). In his field-note he adds: ‘much grown in Chile for the preparation of a refreshing drink made by whisking water with the young shoots and adding sugar. This is very good.’ It is known there by the Indian name ‘culén’. This form should be almost hardy in a sunny sheltered place. At Kew a plant has grown for many years outside the southern end of the Temperate House and flowers freely in summer.
