A game model was developed to examine the evolutionarily stable strategy for the architecture of herbaceous plants. The clones which were considered consisted of leaves, vertical stems and horizontal stems. It was assumed that tall vertical stems are advantageous in light competition with neighbors, and that long horizontal stems decrease self-shading. The model analysis predicted the following four correlations between environmental conditions and the evolutionarily stable architecture of herbaceous plants. (1) A clone allocates all resources to leaves, nothing to vertical or horizontal stems, and forms a rosette in open habitats with low clone density. (2) A clone allocates resources only to leaves and to horizontal stems, but nothing to vertical stems, and creeps on the ground in closed habitats with low clone density. (3) A clone allocates resources only to leaves and to vertical stems, but nothing to horizontal stems, and grows gregariously in open habitats with high clone density. (4) A clone allocates resources to leaves, to vertical stems, and to horizontal stems in closed habitats with high clone density.
