The specific name "tanguticus" is a geographical epithet, signifying 'belonging to the Tangut region' i.e. 'growing in the land of the Tangut people' – which includes the region of Amdo, one of the three traditional regions of Tibet (taking in the modern Chinese province of Qinghai and part of the south of the modern Chinese province of Gansu). Historically, the Tangut, or Western Xia empire included, at its greatest extent, also parts of what are now the Chinese provinces of Ningxia, northern Shaanxi, northeastern Xinjiang, southwestern Inner Mongolia and southernmost Outer Mongolia – all of which in fact lie outside the range of "Anisodus tanguticus".
