Molecular Systematics and Plant Evolution
These conditions are, each in their own distinctive way, intermediate between
hypo- and epigyny. The same could be said of perigynous flowers, in which the
ovary is free but surrounded by a variously shaped hypanthial cup, bearing the
floral ...

The second line of ascent involves a change from the hypogyny to the epigyny
through the pcrigyny. The Resales is characterised by a wide range of floral
structures. Evolutionary changes within the order include the gradual
coalescence, ...

Perigyny occurs throughout the Sesuvioideae, and partly in Aizooideae: weak
epigyny is reported for some Aizooideae. semi-epigyny prevails in
Mesembryanthemoideae and some Tetragonioideae. and complete epigyny is
found in ...

In the second line of evolution a change is observed from hypogyny to epigyny
through perigyny. The change from hypogyny to epigyny is seen clearly in
Rosales. The formation of hypanthodium shows a change of perigyny into
epigyny in ...

Demerits 1. The placing of monocots before the dicots is not sound. 2. Too much
emphasis has been given on hypogyny, perigyny and epigyny. The trend
hypogyny to perigyny to epigyny has arisen again and again in unrelated groups.

The Cambrigde British Flora
The numerous stamens of, for example, the Dilleniaceae and the Cistaceae, may
well be primitive, and probably indicate a common ancestry with the
Ranunculales. In the more specialised (non-British) families gamopetaly and
epigyny occur.

morphology of angiosperms
It is to be expected that numerous intermediate stages between complete
hypogyny and extreme epigyny will be displayed, as may be inferred even from
the doubtful phrases employed by taxonomists to describe them. It also seems to
be a ...

The Origins of Angiosperms and Their Biological Consequences
Epigyny was, however, well established as early as the mid-Cenomanian. The
radiation of epigynous flowers apparently reached a maximum in the Santonian-
Campanian, and epigyny is present in about two-thirds of all recorded floral ...

24B), i.e., neither below nor above as in hypogyny and epigyny. A flower with
such a condition is said to be perigynous and the position of ovary as semi-
inferior. Examples: Primus, Rosa. 3. Epigyny. The thalamus grows around the
ovary and ...

Botanophilia in Eighteenth-Century France: The Spirit of the ...
One may correctly describe the ovary position as superior in all instances of
hypogyny and perigyny, and the ovary as inferior in instances of epigyny. The
knowledgeable botanist in particular needs to be forewarned that the Jussiaean
use of ...
