original: "植物名實圖考" (Zhìwù Míngshí Túkǎo). Compiled by the Qing Dynasty scholar Wu Qijun and published posthumously in 1848, this work is celebrated for its scientific rigor and its focus on verifying the actual plants associated with historical names.

original: "木類" (mù lèi) translates to the 'Category of Trees'; "卷" (juàn) refers to a volume or scroll in traditional Chinese bookbinding.

Doulu Tree

original: "兜櫨樹" (Dōulúshù). This tree is scientifically identified as Dalbergia hupeana. It is a deciduous tree native to central and eastern China, prized for its extremely hard and durable wood, often compared to rosewood.

The name "Doulu" (兜櫨) is historically significant. While the characters themselves are phonetically used here, the term appears in older Buddhist texts to describe aromatic resins or "cotton-like" flowers. However, in this botanical context, Wu Qijun uses the name to identify a specific timber tree known in Hubei and surrounding provinces.
