The newly found states Y(4260), Y(4361), Y(4664) and Z(+/-)(4430) stir a broad interest in the study of spectroscopy in a typical charmonium scale. The Y(4260) which was observed earlier has been interpreted as hybrid, molecular state and baryonium, etc. In this paper we show for the first time that these new structures, which are hard to be interpreted as charmonium states, can be systematically embedded into an extended baryonium picture. According to this assignment, the, so far, known characters of these states are understandable. And, in the same framework, we make some predictions for measurement in future experiments.
