Parastichy
Parastichy, in phyllotaxy, is the (invisible) spiral line of the pattern of the areoles on some plants, such as cactuses and pinecones. These spirals involve the insertion of a single primordium. They have been described as an effect of the human eye and the way it connects "nearest points" on certain spiral patterns.〔(Spiral Lattices, Smith College )〕 ==See also==
