Class I. Dicotyledonous or Exogenous Plants

Series I. Phænogamous or Flowering Plants.

Vegetables bearing proper flowers, that is, having stamens and pistils, and producing seeds, which contain an embryo.

Stems formed of bark, wood, and pith; the wood forming a layer between the other two, increasing, when the stem continues from year to year, by the annual addition of a new layer to the outside, next the bark. Leaves netted-veined. Embryo with a pair of opposite cotyledons, or rarely several in a whorl. Flowers having their parts usually in fives or fours.
