Nyctaginaceae This family has many species and genera with fin-winged fruits formed from accrescent tepals (Spjut, 1994).
The wings, derived from accrescent tepals, are chartaceous and more or less semi-circular.
The membranous wings develop from accrescent perianth (Brandbyge, 1993) and have a fine fusiform-reticulate venation similar to that of Fallopia.
Phylogenetic distribution and identification of fin-winged fruits
