Onagraceae (Evening Primrose) Family


Alternate Leaf Seedbox is a native short-lived perennial or annual in the Evening-Primrose family (Onagraceae). It can be found throughout Alabama; occurring on the shores of streams and ponds, wet ditches, low pastures, in bogs and seeps, and in marshes and swamps. It is a short-lived perennial or annual with a tap root. The stems are 3-4 feet in height and freely branched. The stems are brown in color, slightly winged, and glabrous.

The leaves are alternate, sessile or short petiolate, elliptic to lanceolate in outline, with entire margins; smooth with a few scattered hairs.

The flowers have an inferior ovary. There are 4 triangular sepals and 4 yellow petals. The petals fall off easily.

The fruit is a 4-sided, short capsule; released through a pore in the top of the capsule. The fruit looks somewhat like a salt shaker and is sometimes used in dried flower arrangements. This wetland plant bears a distinctive, box-like fruit; square on top and filled with many seeds.
