Шаблон:Short description Шаблон:Speciesbox
Guilandina bonduc, commonly known as grey nicker, nicker bean,[1] fever nut[2] or knicker nut, is a species of flowering plant in the senna tribe, Caesalpinieae,[3] that has a pantropical distribution.[4] It is a liana that reaches a length of Шаблон:Convert or more and scrambles over other vegetation. The stems are covered in curved spines.[5] Its Шаблон:Convert grey seeds,[6] known as nickernuts,[7] are buoyant and durable enough to be dispersed by ocean currents.[4]
Description
Guilandina bonduc grows as a climber, up to Шаблон:Convert long or as a large sprawling shrub or small shrubby tree. The stems are irregularly covered with curved prickles. The leaves are large and bi-pinnate, up to Шаблон:Convert long with scattered prickles on the rachises and blades. There are four to eleven pairs of pinnae, Шаблон:Convert long with five to ten pairs of pinnules. The pinnules are Шаблон:Convert long, elliptic, oblong or ovate with acute tips and entire margins. The inflorescence is an axillary raceme, often branched, covered with short hairs and up to Шаблон:Convert long. The jointed pedicels are up to Шаблон:Convert long. The sepals are shorter than the petals which are around Шаблон:Convert long; the petals are yellow, sometimes with a spot of orange near the base of the keel. The unisexual flowers are followed by large, flattish, spiny green pods which later turn brown, some Шаблон:Convert, containing one or usually two, glossy, rounded, grey seeds.[1][8][9]
Distribution and habitat
Guilandina bonduc has a pantropical distribution. It typically grows near the coast, in scrub, on sand dunes and on the upper shore.[10] It also occurs inland, in lowland secondary forest and disturbed areas near villages; this may be the result of the seed being accidentally dropped after being transported for medical purposes or for use as counters in board games. The seeds are buoyant and retain their viability in both fresh and sea water, enabling them to disperse to new coastal locations.[11] When washed up on the shore, they are sometimes known as sea pearls.[12]
Uses
Nodules on the plant's roots contain symbiotic bacteria that fixes nitrogen. This is used as a nutrient by the vine and also benefits other plants growing in close proximity.[11]
This plant has been used in traditional medicine. The seeds have tonic and antipyretic properties and the bark and leaves have been used to lower fevers. An oil extracted from the seeds has been used in cosmetics and for treating discharges from the ear.[2]
Tongans make the hard seeds (talatala ‘amoa) into leis or play with them like marbles; its spiky leaves and stems are used in fruit bat snares.[9]
