21.174

樹歧（歧拒羈反兩股間也案字書作𢺷謂樹枝橫首也今經本有從山邊作岐及切韵音之為歧並誤也）。

Tree forks (The fanqie for 歧 is 拒羈 [qí], referring to the fork between two branches. According to character lexicons, it is properly written as 𢺷, meaning tree branches spreading horizontally. Now the sūtra editions that write it with the mountain radical as 岐, and the Qieyun reading it as 歧, are both erroneous).
