title: [The occurrence of hydrocyanic acid in Cormophytes. 18th. Communication. New observations in leguminosae-Papilionoideae (Galegeae, Genisteae, Loteae, Phaseoleae)].
abstract: Cyanogenesis in Galegeae, Genisteae, Loteae and Phaseoleae, four tribes of Leguminosae-Papilionoideae, is discussed thoroughly. Oxytropis campestris (Galegeae) is shown to be facultatively cyanogenic (table I); cyanophoric plants contain a zierin-like glucoside. Lotononis crumaniana (Genisteae) is strongly cyanogenic and contains prunasin. Lotaustralin, accompanied by up to 5% Linamarin was demonstrated to be present in three taxa belonging to Dorycnium pentaphyllum sensu lato (table I). Leaves and stems of Phaseolus lunatus contain linamarin and perhaps trace amounts of lot-australin, but no taxiphyllin- or dhurrin-type glucosides.
