摘　　要：本研究报道了河南柳叶菜科(Onagraceae)一新分布种——卵叶丁香蓼(Ludwigia ovalis)。该种花管和花瓣均不存在,雄蕊和萼片均为4,且萼片花后宿存等与近缘种区分明显。该植物过去记载仅分布于长江以南,而其分布在河南光山县(114°80'E,31°87'N),应该是其现在自然分布区的最北边界。Ludwigia ovalis,is reported as a newly recorded water plant from Henan province. It differs from its allies with 4 stamens,4 sepals deposited on the fruits,but no corolla tube or petal. The species was previously found only in the south area of the Changjiang River,and its distribution from Guangshan county in Henan（114.80,E,31.87,N） should be the most northern boundary toward its natural area.
