Abstract:
In the present paper, the morphology and structure of the flower, fruit
and seed of Kingdonia uniflora are reported. Each part of the flower is usually indefi-
nite and is spirally arranged. The venation of the tepals is open-dichotomous and cla-
ssified into three types. There are two types of the stamens, which have a solitary bun-
dle; the sterile stamens bear nectaries in the ventral furrows of the apex, and the pollen
sacs of the fertile ones are lateral-extrose. The carpel is differentiated into three parts,
and is not completely closed in flower, which represents a half-opened type and is si-
millar to that of Coptis. The fruit is an achene. The embryo is at the stage of proem-
bryo when the fruit is mature. The endosperm is copious. In this paper, some problems
concerning morphological evolution are also discussed.
