Ifloga

"A fairly common desert plant. Ifloga spicata is polymorphic in habit concerning characters like height of the plant, degree of branching, density of inflores¬cence and indumentum. Several subspecies have been described by Chrtek from Egypt. But as many of these characters are influenced by the environment, hence a more thorough study of the species in its entire range of distribution is necessary before recognizing infraspecific taxa" ~Flora of Pakistan (efloras.org)
