Phylogenomic and morphological evidence reveal a new species of spider lily, (Amaryllidaceae) from China.

, a new species from China, was described and illustrated here. Our phylogenomic evidence based on whole plastomes strongly supported the separate phylogenetic position of this new species, and morphologically it could also be distinguished by its long leaves with a distinct purplish-red midrib on the abaxial surface.

[Community structure and leaf trait diversity in a vulnerable species, Phoebe chekiangensis (Lauraceae).].

Phoebe chekiangensis, as one original species of 'Nanmu with golden tint', harbors limited natural distribution regions, which is recognized as a vulnerable species in China under nationwide protection. Under the background of global climate change, it is of scientific significance to study the community structure and diversity of the natural populations of P. chekiangensis.

[Simultaneous determination of four glycosylflavones from Lophatherum gracile by RP-HPLC].

Objective: To develop a RP-HPLC method for simultaneous determination of orientin, isorientin, vitexin and isovitexin in Lophatherum gracile from different habitat and harvesting time.

Method: The HPLC method was applied and the chromatographic column was a Waters XBridge C18 column (4.6 mm x 250 mm, 5 microm).

[Analysis of the inter-species relationships on lycoris Amaryllidaceae) by use of RAPD].

The fingerprints of 13 species in genus Lycoris were generated by use of RAPD method. Forty-one primers were screened from 520 random primers, and a total of 350 DNA fragments were amplified ranging from 0.3-3.
