We surveyed leaf material of 545 individual palms representing 108 genera a
nd 155 species for cyanogenesis using the Feigl-Anger test. We detected HCN
production in only two species of one genus, Drymophloeus. Additional smal
ler surveys of shoot meristems and roots revealed cyanogenesis only in the
shoot meristem of one species of Dypsis, Our results indicate that cyanogen
esis is rather rare in the family. (C) 2000 Elsevier Science Ltd. All right
