  Hence he [scil. Raunkiaer] proposes a new classification, based on resting buds and other organs that are most in evidence in rigorous seasons. On this basis five great plant classes are recognized: phanerophytes, whose buds are considerably above the ground (trees and shrubs); chamephytes, whose buds are slightly above the ground; hemicryptophytes, whose buds are at the ground level; cryptophytes, whose buds are hidden in the ground; and therophytes, whose buds persist only in seeds (annuals).

  His [scil. Raunkiær’s] five chief groups were phanerophytes, chamaephytes, hemicryptophytes, cryptophytes, and therophytes.
