Comments

provided by eFloras
Quercus muliensis Hu (Acta Phytotax. Sin. 1: 147. 1951), from Sichuan (Muli Zangzi Zizhixian), is probably a hybrid between Q. senescens and Q. monimotricha. It has also been treated as Q. senescens var. muliensis (Hu) Y. C. Hsu & H. W. Jen (J. Beijing Forest. Univ. 15(4): 44. 1993). Quercus muliensis has the growth habit and leaf dimensions characteristic of Q. monimotricha but the leaf and branchlet indumentum characteristic of Q. senescens.
