Stamen centrifugal

Centripetal versus centrifugal stamen initiation in polystemonous androecia... [Pg.130]

The subclass Dilleniidae was introduced into angiosperm macrosystematics by Takhtajan (1964) largely influenced by the occiurence of centrifugal stamen initiation in polymerous androecia, which was supposed to be a fundamentally important pattern in macrosystematics. However, the subclass was later dismantled, first by structural cladistic studies (Hufford, 1992) and then also by molecular studies (Chase et al., 1993) (see also Endress et al., 2000). From the present perspective, the feature is not stable at very high systematic levels, however, often it is still at family level. [Pg.130]

Polyandry is reported in most genera of Lecythidaceae with multiple stamens arising centrifugally on a ring primordium (e.g. Endress, 1994 Appel, 1996 Tsou and Mori, 2007). Except for Napoleonaea with strongly differentiated outer stami-nodes, the androecium consists generally of fertile stamens, well delimited from the showy outer corolla. [Pg.291]

It is demonstrated that the corona represents a complex structure, which is part corolla and part androecium, represented by two series of distinct staminodes. The argument that the flower is apetalous because of the strong resemblance and association of outer petaloid appendages to the stamen tube gains little support because of the initiation of petal lobes before the androecium and from the fact that petals and stamens are connected by a common stamen-petal tube, which is widespread in asterids. A floral developmental study of genera of Scytopetaloideae, Crateranthus and Astemnthos is expected to confirm the earlier initiation of the outer corolla before the centrifugal development of the androecium. [Pg.292]
