perigynous การใช้

• The flower is perigynous ( sepals, petals and stamens around the edge of the ovary ) the ovary is superior.
• Between these two extremes are " perigynous " flowers, in which a hypanthium is present, but is either free from the gynoecium ( in which case it may appear to be a cup or tube surrounding the gynoecium ) or connected partly to the gynoecium ( with the stamens, petals, and sepals attached to the hypanthium part of the way up the ovary ).
• When Robert Brown created the family Limnanthaceae in 1833 he declared that, " the place of this new family is not absolutely determined; but it is suggested that in two remarkable points of its structure, namely, the presence of glands subtending the alternate filaments, and the existence of a gynobase, it more nearly approaches to Hypogynous families than to Perigynous, with which it has hitherto been associated ".
