Notes made (JMG) on this species at Howick in 2005 use the word ‘elegant’ twice, and the same epithet was applied, in 2006, in notes on the specimen at Kew. The individuals observed are in both cases young, the Howick plants (4 m tall in 2005) having been grown from Shanghai Botanic Garden seed (SBG 93/24), while the one at Kew (3 m in 2006) is from SICH 2058. This was collected in 1999 at 1745 m in the Gwangwu Shan, Sichuan, from trees surviving amidst a failed conifer plantation. Both specimens have a single main stem with spreading branches and weeping branchlets, bearing pointed mid-green leaves. The 10 m tree noted by Rushforth (1985) at Kew has disappeared. At Rogów Arboretum trees from Emei Shan are not fully hardy (P. Banaszczak, pers. comm. 2007).
