The identification of the seeds of the British papaveraceae

Abstract

The morphology of seeds of British wild, introduced, and commonly cultivated members of the Papaveraceae has been examined, and a key to the identification of the seeds is presented.Quantitative data on size and weight as well as information about shape, colour and surface features of the seeds are given for Papaver rhoeas L., P. dubium L., P. lecoqii lamotte, P. hybridum L., P. argemone L., P. somniferum L., P. lateritium C. Koch, P. atlanticum (Ball) Coss., P. orientale L., P. nudicaule L., Meconopsis cambrica (L.) Vig., M. betonicifolia French, Roemeria hybrida (L.) DC., Glaucium flavum Crantz., G. corniculatum (L.) Rudolph, Chelidonium majus L., Eschscholzia californica Cham., E. erecta cv. compacta and E. erecta cv. miniature. A representative sample of each seed is illustrated. © 1970 OXFORD UNIVERSITY PRESS.
