[Botany • 2024] Polygala qii (Polygalaceae) • A New Species from Limestone Landform in Southern Hunan, China | Mio Kitchen


 

Abstract

Polygala qii, a new species, is described and illustrated from limestone landform in southern Hunan, China. The new species resembles P. fallax and P. arillata in flower structure of the plants, but readily differs from the latter two in having erect and shorter inflorescences (0.2–1cm VS 10–15cm VS 7–10cm), and fewer flowers (1–5 flowers VS 10–30 flowers VS 10–20 flowers), and the latter two have a later flowering period (late March to mid-April VS May to August VS May to October). And it is an extremely unique new species that will hibernate in the hot summer of July and August. Following the IUCN Red List Criteria, P. qii is assessed as ‘Data Deficient (DD)’.

Key words: Hunan province, limestone landform, new species, Polygala, taxonomy

Don, but it differs from the latter two in having erect and shorter inflorescences (0.2–1cm VS 10–15cm VS 7–10cm) and fewer flowers (1–5 flowers VS 10–30 flowers VS 10–20 flowers). Its caruncle is foam, and the latter two are helmeted in shape. Please refer to Fig. 3 and Table 1.

Etymology: The new species is named after Professor Cheng-jing QI (CSUFT&CSFI), who has made great contributions to the study of Hunan flora (Qi & Yu, 2002).
