槲樹（上胡谷反木名也考聲葉似松而細爾雅云樕撲心郭注云槲樕別名從木斛聲經文作穀亦通用）。

槲樹 (the first character is h[ú] + g[ǔ] fanqie; the name of a tree. The Kaosheng says: "The leaves resemble pine but are slender." The Erya states: "Sù is pūxīn." Guo's commentary notes: "Húsù is another name for it." Composed with the wood radical and hú phonetic. In the scripture text it is written as 穀, which is also interchangeably used).
