Saussurea melanotricha is very close to S. spatulifolia and probably not clearly separated at species level. The type specimen of S. xanthotricha from Sichuan holds an intermediate position between S. spatulifolia and S. melanotricha, combining the acuminate phyllaries with yellowish indumentum of the former with the sinuate-dentate leaf margins with purple mucros of the latter.
