The upper two anthers of this inner whorl are fertile in Cypripedium, and in other eases are generally represented either by membranous expansions or by minute auricles without spiral vessels. These auricles, however, are sometimes quite absent, as in some cases of Ophrys." On this view of the homologies of Orchid flowers, Darwin f
