Flora of China
Cotoneaster distichus Lange var. duthieanus C. K. Schneider, Ill. Handb. Laubholzk. 1: 745. 1906; C. duthieanus (C. K. Schneider) G. Klotz; C. forrestii G. Klotz.
Leaf blade 1.2–2.5 × 1.2–1.8 cm, apex acute and shortly mucronate.
Further study is necessary to determine the identities of Cotoneaster cuspidatus Marquand ex J. Fryer & B. Hylmö and C. marquandii G. Klotz, which might be synonymous with this taxon.
Brach (2010): This is instead Cotoneaster adpressus Bois (see Dickoré & Kasperek 2010).
Mountain regions; 2500--4000 m. NW Yunnan [N Myanmar].
