1. The time intervals among successive appearance of new tillers in the ruch plant may vary according to the environmental conditions around the plant. From the results of the author's observations, however, it was ascertained that, under a definite condition, the number of days for every new tiller to develope in succession was nearly constant in this plant. 2. Every tiller appears on the second or third, sometimes even on the fourthnode of the mother stem. The author denominated the series of superposed tillers, each from the second node of the preceding one, as the "first tillering rank", and the series just analogous to that in construction, but starting from the third node of the stems of the "first tillering rank", as the "second tillering rank", and so on. (Fig. 1) The appearance of the third stem of the "first tillering ranp" occurs almost at the same time as that of a tiller from the third node of the first stem of the same rank. Such systematic and synchronic behavior of tillering lasts in the further course of growth. 3. Therefore, either the tillers which should appear at the same time, or the existent number of tillers of the whole plant may be given by a simple numerical formulation based on the tiller orders in the "first tillering rank".
