laburnumn.

Brit.

/ləˈbəːnəm/, U.S.

/ləˈbərnəm/

Forms: 1500s– laburnum, 1700s liburnum.

Origin: A borrowing from Latin. Etymon: Latin laburnum.

Etymology: < classical Latin laburnum (Pliny), in scientific Latin also as a genus name (1759: see note at definition), of unknown origin.

1. Either of two small trees having trifoliolate leaves and pendulous racemes of bright yellow flowers followed by long seed pods, Laburnum anagyroides and Laburnum alpinum (family Leguminosae ( Papilionoideae)), native to central and southern Europe but widely cultivated elsewhere (sometimes as hybrids between the two species); (in form Laburnum) the genus comprising these trees. Also: the hard dark wood of these trees, used esp. in joinery.Common names for the laburnums include golden chain, golden rain, and (formerly) bean-trefoil. Their seeds and other parts contain the toxic alkaloid cytisine, in quantities potentially lethal to small children and livestock.Valid publication of the genus name: F. K. Medikus 1787, in Vorlesungen der Churpfälzischen physikalisch-ökon. Gesellschaft 2 362, after earlier use as a genus name by P. K. Fabricius ( Enum. Meth. Plant. Hort. Med. Helmstadiensis (1759) 228), and as a specific epithet (in Cytisus laburnum) by Linnaeus (1753).
