0383446DFFAAFFAD16A8F9AF3B50FE3F.taxon	distribution	Distribution: This species is commonly distributed in Japan and southern Korea (Ohashi et al. 2006, 2007), with a very limited distribution in SE China (Guangdong province and Hongkong) (Deng et al. 2008). Leaf epidermal features: The abaxial leaf surfaces were covered by platelet wax flake. The epidermal cells of the abaxial surface were flat and polygon-irregular in shape. The appressed lateral attached trichomes (ALA) (Fig. 5 A and B, shown by black arrows) and solitary uniseriate trichomes (U) (Fig. 5 A and B, shown by white arrows) were commonly present on the abaxial surface. The stomata were non-typical cyclocytic type. The stomata size (L × W) is 18.39 ± 0.56 × 16.84 ± 0.56 with the stomatal frequency 808.2 ± 6.8 / mm 2. Observations: Q. acuta is similar to Q. sessilifolia Blume and Q. morii Hayata. It differs from Q. morii in its almost entire leaf margin. It differs from Q. sessilifolia in its elliptic or ovate leaf blade and long petiole of about 2.0 – 2.7 cm, compared to the oblong-elliptic to lanceolate-elliptic leaf blade and petiole 0.5 – 1.0 cm in Q. sessilifolia.	en	DENG, Min, LI, Qiansheng, COOMBES, Allen, XU, Jin (2013): Typification of Quercus acuta Thunb. and Q. glauca Thunb.

0383446DFFADFFAF16A8FD843A8CFD2C.taxon	distribution	Distribution: This species is widely distributed in subtropical regions of E and SE Asia. Leaf epidermal features: The plant materials used for leaf epidermal studies represented typical Q. glauca from Japan. The leaf abaxial surface was covered by platelet wax flake (Fig. 5 C). The ALA trichomes (Figs. 5 C & D) were generally present on the abaxial leaf surface and the hair colour is from white to grayyellow. U trichome was also found, but rare. The epidermal cells were flat, and irregular to polygonal in shape. The stomata were non-typical cyclocytic type. The stomatal size (L × W) is 25.0 ± 0.9 × 20.2 ± 0.5 µm with the stomatal frequency 641.8 ± 7.2 / mm 2. Observations: The taxonomy of Q. glauca and closely related species (Q. myrisinifolia Blume, Q. schottkyana Rehder & E. H. Wilson, Q. ciliaris C. C. Huang & Y. T. Chang, Q. hypargyrea (Seemen) C. C. Huang & Y. T. Chang., Q. oxyodon Miquel., Q. stewardiana A. Camus) is confusing because of the sympatric distribution pattern of those species, and continuous morphological variations among the different populations (Deng 2007). Q. glauca can be distinguished from related species by the prominent secondary leaf veins, the smooth, straight ALA trichomes, the almost glabrous acorn cupule wal 1, the one-year acorn maturation and smooth epidermal cells of the abaxial leaf surface. Future studies to compare the morphological variations of different populations of Q. glauca and its relatives are needed to clarify the taxonomic confusion of this group.	en	DENG, Min, LI, Qiansheng, COOMBES, Allen, XU, Jin (2013): Typification of Quercus acuta Thunb. and Q. glauca Thunb.
