| contents | For any cardinal $κ\geq 2$, there is a unique complete real tree whose points all have valence $κ$. In this note, we show that, when $κ\geq 3$, it is necessary to assume completeness. More precisely, we show that there exist uncountably many homogeneous incomplete real trees whose points all have valence $κ$. |
