Author has analyzed models, that describe the development of a fine pattern on diatoms valves, and have found that those models approximately simulate areolae topology. Since the branching structures of siliceous ribs form the basis of morphogenesis of diatoms areolae patterns, to model them, author suggests to use L-system. It perfect describes the development of dichotomous processes. Author describes L-systems that simulate one- and double-sided radial-parallel patterns and double-sided spiral pattern (spiral phyllotaxis) of areolae rows on centric diatoms.
