Abstract
In this paper, a new species from Central China, Amana hejiaqingii (Liliaceae), is described and illustrated. It resembles A. anhuiensis and A. tianmuensis but differs from A. anhuiensis as it has one white vein on its lower leaf and yellow anthers. It also differs from A. tianmuensis by possessing solitary pink flowers with longer and wider tepals. The principal coordinates analysis separated the three species based on morphological data. Cytological observation showed that A. hejiaqingii is diploid (2n = 2x = 24). Molecular phylogenetic analyses further supported its species delimitation.

Amana hejiaqingii M.Z. Wang & P. Li, sp. nov.
(Chinese name: 大别老鸦瓣)
Diagnosis: This new species resembles Amana tianmuensis P. Li & M.Z. Wang in possessing yellowish-brown, thinly papery bulb tunics, oblanceolate leaves and three verticillate linear bracts, but differs from it as it has solitary pink flower (vs. solitary, sometimes two, white) with longer wider tepals.
Distribution and habitat: Up to now, Amana hejiaqingii is found in eight localities across 233.7 km in the Dabie Mountains bordering Henan and Hubei provinces. It grows in moist deciduous broad-leaf forests on mountain slopes at elevations of 70–530 m. In future investigations, we think that more populations will be found in the area in and around these localities.
Etymology: The specific epithet is named in memory of Professor Jia-Qing He, a Chinese botanist who was dedicated to plant investigation in the Dabie Mountains. He walked about 12,684 km and collected nearly 10,000 specimens during a 255-day fieldtrip in the Dabie Mountains, becoming the first person ever to make a comprehensive wild plant investigation of the Dabie Mountains.
