ED45878D9830B95FFF1FFD47E7C04FCA.taxon	distribution	Distribution and habitat: Scutellaria albovillosa is currently known only from its type locality, i. e. Yangchun city in southwestern Guangdong province, China (Fig. 6). It grows on limestone slopes at an elevation of 50 m a. s. l. Phenology: — Flowering from March to April.	en	Zeng, You-Pai, Xu, Ye-Chun, Chen, Guo-Di (2025): Taxonomic studies on Scutellaria (Lamiaceae) from China (I): two new species from southwestern Guangdong province.

ED45878D9830B95FFF1FFD47E7C04FCA.taxon	etymology	Etymology: — The specific epithet refers to the white long hairs on the plant body of the new species. Vernacular name: — Hƚff ẓ, bai mao huang qin in Chinese Pinyin. Conservation status: — Scutellaria albovillosa is currently known only from its type locality, Yangchun city. Only approximately 20 individuals were discovered in this population, which is situated the Kongdongyan Scenic Spot, and thus are quite vulnerable to human activities. Yangchun city is an area not yet well botanized, and we do not know if more populations of this new species can be discovered in the future. The distribution and other information of this species are far from adequate to make a precise and accurate assessment of its risk of endangerment. Thus, given that newly described species are attributed to very different IUCN (2024) categories, ranging from the highest threat category, i. e. CR (El Zein & Bottcher 2024), to not threatened, i. e. categories NT (Perrino et al. 2018) and LC (Siti-Munirah & Dome 2023), the conservation status of this species should be previously considered as “ Data Deficient (DD) ” and further investigation on this species is required for its proper assessment (IUCN 2024).	en	Zeng, You-Pai, Xu, Ye-Chun, Chen, Guo-Di (2025): Taxonomic studies on Scutellaria (Lamiaceae) from China (I): two new species from southwestern Guangdong province.

ED45878D9836B953FF1FFB7BE1904035.taxon	diagnosis	Diagnosis: — Morphologically Scutellaria yangchunensis resembles S. wongkei (Figs. 4, 5) in habit and in having upwardly curved hairs on the stem and rachis, bracts similar to leaves and gradually reduced, and bluish or lilac flowers, but differs for its leaves and bracts shallowly serrate or entire (vs. crenate) at the margin (Figs. 4 B, 5 B, D, 8 D, E), hirtellous only on veins (vs. totally hirtellous on both sides) (Figs. 4 B, 5 D, 8 D), and middle lobe of lower lip of corolla dark purple spotted (vs. whitish) (Figs. 5 B, D, 8 F, H). From S. albovillosa, S. yangchunensis is readily distinguishable by having short (ca. 0.1 mm vs. ca. 0.5 mm long), upwardly curved and eglandular (vs. erect and glandular) hairs on the stem and rachis (Figs. 2 B, C, 8 B, C), leaves and bracts shallowly serrate or entire (vs. crenate) (Figs. 2 D, E, 8 D, E), and corolla tube base not saccate (vs. saccate, with a ca. 0.8 mm long sac) (Figs. 2 F, 8 F).

Vernacular name: — Ḇǝffẓ, yang chun huang qin in Chinese Pinyin. Conservation status: — Scutellaria yangchunensis is currently known only from its type locality, Yangchun city. Only approximately 50 individuals were discovered in this population and are quite vulnerable to human activities, as this population is situated very closely to residential area (less than 200 m). Similar to S. albovillosa, all our knowledge of this new species relies on the single population we visited, the conservation status of S. yangchunensis thus should also be considered as “ Data Deficient (DD) ”.	en	Zeng, You-Pai, Xu, Ye-Chun, Chen, Guo-Di (2025): Taxonomic studies on Scutellaria (Lamiaceae) from China (I): two new species from southwestern Guangdong province.
