 These plants compose a shrub cover up to 30 cm in height and are intermixed with "Eclipta", "Phyllanthus", and "Solanum", as well as a taller plant, "Brassica juncea".A unique feature is that the vegetation is arranged in parallel rows of species, with dense rows of taller species alternating with lower, more open vegetation.This was assumed to be a result of the phosphate mining method of trench-digging.
