This is from a slender erect shrub, which grows up to 1 metre tall and usually found surrounded by taller shrubs and grasses. You can see that at each attachment point for a leaf, the stem is broadened giving the stem a winged appearance.
Also shown in the inset, there are at each leaf attachment point, spiky looking stipules (small leaf like structures between the leaf and the stem).
