False Smooth Buttonweed
Spermacoce glabra Michaux
Rubiaceae (Madder or Coffee) Family

False Smooth Buttonweed is perennial with a taproot. It is considered a pest in most gardens. Its preferred habitat is almost any environment; sandy locations, disturbed areas, rocky slopes and swamp bottoms. Distribution is throughout the Escambia region.

The leaves are lance-like, smooth above and often hairy beneath. The stems are smooth and woody. There is a prominent central vein with numerous obscure side veins. Leaf stalks are short but may appear to be sessile. Leaves usually emerge at the stem node which also produces a green button of flowers and seeds.

The flowers are white, small and emergent from a series of close-knit bracts. Each flower has four petals and a tube-like corolla. The flowers are bisexual in nature and symmetrical in form. Flowers occur in the summer and autumn.
