Manglietia guangzhouensis sp. nov. (Magnoliaceae) from Guangdong, China

Manglietia guangzhouensis A. Q. Dong, Q. W. Zeng & F. W. Xing, a new species of Magnoliaceae from Guangdong province, China, is described and illustrated. It is closely related to M. pachyphylla H. T. Chang, but differs primarily in its brown villose lower surface of leaves, brown tomentose and stout brachyblasts (peduncles), absence of pedicels, sparsely brown pubescent outer tepals and more numerous ovules (12–14) in each carpel. It is a very rare species with a highly restricted distribution.
