Species in which seed and chaff are extremely similar insize, weight and colour include E. cloeziana, E. regnans and E. delegatensis.other small-seeded genera in which separation of pure seeds is difficult areAlnus, Betula, Populus and Salix. Even when separation is possible in thesespecies, it is very time-consuming.
