An emigrant from tropical America, which is gradually gaining ground to the north and the west. Stems eight to twenty inches high, erect, much branched, downy-hairy. Leaves alternate, one to two inches long, ovate to lance-shaped, scallop-toothed, downy-hairy, with base rounded or abruptly narrowed to petioles about half as long as the blades; at the base of some of the larger leaves is a small, pointed tubercle, which gives the plant its name though it is hardly long enough or sharp enough to be called a spine. Flowers light yellow, only about a quarter-inch broad, on short axillary peduncles; calyx with five teeth, shorter than the obovoid petals; styles five with undivided stigmas, surrounded by united stamens. Fruit ovoid, containing five carpels, each splitting at the top into two beaks. Seeds triangular, smooth, dark brown. (Fig. 195.)
