The plumule is too small to be seen without alens. When drawing a pine seed, draw the seed-coat around theendosperm. A thin papery layer will be found between the once contained food. Draw it by a light line inside theseed-coat. In the Hottentot fig or Tgaukum (Mesembrianthemiim)the embryo is curved around the endosperm. Examine some seeds of mealies or Indian corn {Zea.
