Orixa japonica i hunb. (Rutaceae), Lagerostroêmia indica L. (Lythraceae) and Berchemiella berchemiaefolia Nakai(Rhamnaceae)have peculiar alternate leaf arrangements, in which every two leaves combine to alternate on branches. It is an intermediate type of phyllotaxis, induced from the decussate type through the longitudinal dispersion between two members of each opposite pairs, instead of the change of orthostichy, and I call it Orixate Type (Folia orixata) after the genus name Orixa.By the connection of this intermediate type, one of the tendency in phyllotaxis of dicotyledoneous plants will be formulated as follows:-(1) Decussate type-(through longitudinal dispersion)→(2) Orixate type-(through oligomery)→(3) Distichous type-(through horizontal dislocation i. e. spirality)→Quincuncial type.
