Morphology and phyletic relationship of the Glaucidiaceae

  • Michio Tamura
Article

Abstract

Glaucidium is different from the Ranunculaceae by (1) pistils grooved along ventral and dorsal sutures and fruits dehiscing along both sutures, (2) thick integuments, the outer one 6 to 13 and the inner one about 5 cell layers thick, (3) staminal traces formed by repeated splitting of receptaclar bundles, (4) centrifugal initiation of stamens, (5) somatic chromosome number being 20, (6) occurrence of coumarin, etc. These and other characteristics are referred to related families. As a results of this, a monotypic new family, Glaucidiaceae, is described, and its phyletic relationship is discussed. The author considers that it is better to include this family in Ord. Hypericales.
