Abstract： Diospyros dasyphylla Kurz and Diospyros sumatrana Miq. ( Ebenaceae ) are reported as newly recorded species in China. Their diagnostic characters, habitat and distribution of the two newly recorded species are provided. The endangered category of the two newly recorded species is assessed based on field survey. D. dasyphylla closely resembles D. xylocarpa Y. M. Shui, W. H. Chen & Sima, However, it can be distinguished by its young branchlets and leaves, which are densely covered with yellow-brown hairs. Another distinctive feature of D. dasyphylla is its mature fruit, approximately 6 cm in diameter, accompanied by a fruit calyx measuring 8 mm. D. sumatrana is similar to D. elliptifolia Merr., but differs in its white and urceolate corolla, fruit 2 cm in diameter and erected calyx. The voucher specimens are deposited in Herbarium of Guangxi Institute of Botany ( IBK ) and Museum of Beijing Forestry University ( BJFC ). These findings provide new basic data for the biodiversity research of Diospyros plants in China.

Abstract： Based on literature research, specimens identification and field investigation, we systematically cleared up the early researches of Sedum and conducted an overview for the species diversity of Sedum in Guangxi. There are 17 species was confirmed, among which six species are newly recorded. At first, the research brief histories of Sedum taxonomy in Guangxi were summarized. The following is the revised information for S. polytrichoides Hemsl. Six newly recorded species of Sedum are reported here, which are S. leblancae Hamet., S. lipingense R. B. Zhang, D. Tan & R. X. Wei, S. lungtsuanense S. H. Fu, S. makinoi Maxim., S. subtile Miq., S. tosaense Makino. The morphological feature diagnosis and photographs for these newly recorded species were provided. Finally we also discussed the species diversity and the potential utilization of Sedum in Guangxi. It is hoped to provide background information for the subsequent research and utilization of this genus.

Fern. is found from Guangxi for the first time. There about 30 species of Tripogon in global, and majority species are distribution in Asia and Africa, including 11 species in China. A species, Tripogon filiformis Nees ex Steud. is found from Guangxi for the first time.
