| 摘 要： | 本文报道独叶草 Kingdoinia uniflora 的花、果实和种子的形态结构规律。 花的各部分
多而无定数，呈螺旋状排列。花被片的脉序呈开放的二叉分枝，可分三类。雄蕊分能育和不
育两类，维管束单一，后者顶端的凹沟内具蜜腺，前者的花粉囊呈侧向-外向着生。心皮分化
为三部分，子房具柄，含1枚横生胚珠。开花时，心皮不完全闭合，属半开放型，近似黄连属(Coptis)植物。聚合瘦果，种子1枚，胚处于原胚期，胚乳丰富。文中还讨论了有关形态演化问题。

| 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. |
