Note 1.

The genus Yulania   Spach ( Spach 1839) was resurrected in Flora of China ( Xia et al. 2008), but there has not been universal acceptance of this in China, with Yulania   again recognised as a subgenus under Magnolia   (Ying et al. 2009, Yang et al. 2016).

Note 2.

Yulania pilocarpa var. ellipticifolia   is sufficiently distinguished from Y. pilocarpa   to maintain its varietal status by the following features: indumentum of the branchlets (densely pubescent, later glabrous vs. glabrous [Law et al. 2004: 93]); the leaf shape (elliptical, rarely inverted-triangular vs. obovate to broadly obovate [Law et al. 2004]) and the shape and size of the inner 6 tepals (petaloid, 5-7 × 2-3.2 cm vs. nearly spathulate, 7-10 × 3-5 cm [Law et al. 2004]). Additionally, the two taxa are geographically isolated (central Henan Province vs. SE Hubei Province). The illustration of the leaves accompanying the original description of Yulania pilocarpa var. ellipticifolia   ( Fu et al. 2007: fig.1D) shows them to be in stark contrast to the leaves of Magnolia pilocarpa   illustrated in Liu et al. (2004: 93).
