931AEDC0724056BEBE43BB595B220C46.taxon	diagnosis	Diagnosis. Breynia hiemalis can easily be distinguished from all morphologically similar species by plants glabrous throughout, by its broadly elliptic to orbicular and relatively small (4 - 21 x 4 - 17 mm) leaves, calyx of staminate flower shallowly plate-like, ovary rim conspicuously erose, and the urceolate capsule with a raised and lobed apical rim.	en	Yang, Feng, Chen, Chao, Ye, Jing-Yi, Wu, Jian-Yong, Wang, Huan-Chong (2022): Breynia hiemalis (Phyllanthaceae, Phyllantheae), a new species from Yunnan, south-west China.

The epithet '' hiemalis '' is Latin for '' belonging to winter' ', referring to the flowering period of this new species.	en	Yang, Feng, Chen, Chao, Ye, Jing-Yi, Wu, Jian-Yong, Wang, Huan-Chong (2022): Breynia hiemalis (Phyllanthaceae, Phyllantheae), a new species from Yunnan, south-west China.

931AEDC0724056BEBE43BB595B220C46.taxon	distribution	Distribution and habitat. Breynia hiemalis appears to be rare and is endemic to Yunnan, south-west China. It is known from only a single locality in the valley of the Yuanjiang River, which flows from Yunnan (south-west China) through northern Vietnam to the Gulf of Tonkin (Fig. 4). The climate in Yuanjiang valley is characterized by a long dry season (the dry season can be further divided into a cool dry season (November to February) and a hot dry season (March to April )), with an annual average temperature of 24 ° C and a mean annual evaporation capacity of 2700 - 3800 mm, that is three to six times higher than the mean annual precipitation (600 - 800 mm), and with 80 - 90 % of the precipitation concentrated in the wet season (from May to October) (Jin 2002; Shen et al. 2010; Zhou et al. 2017). Breynia hiemalis grows in savanna on a mountain slope (Fig. 5) at elevations of 500 - 700 m, together with Lannea coromandelica (Houtt.) Merr. (Anacardiaceae), Adina cordifolia (Roxb.) Brandis (Rubiaceae), Bauhinia brachycarpa Wall. ex Benth. (Fabaceae), Tephrosia purpurea (L.) Pers. (Fabaceae), Woodfordia fruticosa (L.) Kurz (Lythraceae), Waltheria indica L. (Malvaceae), Jasminium mesnyi Hance (Oleaceae), Searsia paniculata (Wall. ex G. Don) Moffett (Anacardiaceae), Heteropogon contortus (L.) P. Beauv. ex Roem. & Schult. (Poaceae), and others.	en	Yang, Feng, Chen, Chao, Ye, Jing-Yi, Wu, Jian-Yong, Wang, Huan-Chong (2022): Breynia hiemalis (Phyllanthaceae, Phyllantheae), a new species from Yunnan, south-west China.
