Quercus dolicholepis A. Camus

An attractive species, featuring white hairs on the stems and sparse creamish pubescence on the underside of the glossy leaves. The cupules, with long slender scales, reflexed at top and spread out at the rim, are a particularly notable feature, distinguishing it from similar species.

Quercus dolicholepis was apparently first introduced by the Fliegner, Howick, McNamara, and Staniforth expedition to Sichuan in 1992, under the number SICH 982. The parent was noted to be 5 m in height, growing on a steep mountainside at ~2510 m, with rhododendrons, pines, and other shrubs. In cultivation it seems as if this height may be exceeded, as the specimen at Kew is now ~4.5 m tall, forming a small, bushy tree. The stem forked close to the ground and the tree is built around multiple vertical stems in its centre, forming a dense and rather dull dark green mass (Grimshaw & Bayton 2009).

Plants originally distributed as Q. acrodonta by the Alpine Garden Society Expedition to China in 1994 (ACE 1978) and collected from a calcified hillside near San-ba, Yunnan, belong here. It is grown at White House Farm, Kent, UK with smaller plants in other collections. The parent was described as an evergreen tree to 10 m with dark green foliage, paler beneath, leaf shape very variable; acorns protruding only a few mm from the ‘mossy’ cups.

A tree at Arboretum des Pouyouleix, France, from seed collected in Yunnan in 2004 (CMBS 899), reached 7 m × 9 cm dbh in 2020 (B. Chassé, pers. comm.); at Arboretum de la Bergerette, France, a specimen planted in 1999 had reached 4.4 m in 2008 and 6.1 m in 2018 (S. Haddock, pers. comm.). At Chevithorne Barton, England, a tree from the same source has reached similar dimensions (6.9 m × 9.5 cm dbh) in 2020 (J. MacEwen, pers. comm.). At the Sir Harold Hillier Gardens, England, a plant from Cao Ming 316, collected as Q. spinosa in Yunnan in 1998 lost its top in the 2005–2006 winter, but was 4.5 m × 14.1 cm diameter at 1.3 m in 2020 (B. Clarke, pers. comm. 2020).

Initially described in 1897 by Seemen as Q. spathulata, but Camus renamed it in 1953 because Q. spathulata had been used previously to name a fossil. The epithet refers to the long scales that adorn the cupule; it derives from Ancient Greek: δολιχός (dolikhós) = long + λεπῐ́ς (lepís) = scale.
