Abstract：The native leguminous species, C. licentiana, C. opulens and C. intermedia, can produce many ramets by rhizome. They exhibited sympodia branching pattern and "guerilla" architecture and have strong ability to spread at horizontally. The persistent rhizomes formed closely crowed below ground networks for this native species. No ramets induced from root in C. intermedia . Authors suggested that vegetative expansion is a regeneration strategy for C. licentiana when seed germination and seedling establishment restricted by relative drought and animal predation. Compared with that in the north-facing sloping hill, the ramet population in the south-facing sloping hill of C. licentiana exhibited significantly more ramets and longer rhizome intemode and greater biomass allocation to rhizome but similar ramet height, which show morphological plasticity for C. licentiana .
