Abstract

Abstract:

Parakmeria lotungensis is a rare and endangered plant endemic to China. Based on intensive field surveys, we chose 10 plant communities where relatively more individuals of P. lotungensis were found. Based on these surveys, we developed a checklist of 477 plant species, belonging to 237 genera and 110 families. Dominant tree layer species belonged to the Fagaceae, Lauraceae, Theaceae, and Mognoliaceae plant families, whereas dominant shrub layer species belonged to the Ericaceae, Myrsinaceae, Euphorbiaceae, Symplocaceae, and Aquifoliaceae plant families. A majority of herbaceous layer species belonged to fern families, such as Dicranopteris linearis, Lindsaea chienii, Woodwardia japonica, and Blechnum orientale. We found that most species occurred in only one or relatively few communities and there are no obligate plants which associate with P. lotungensis.

Key words: Parakmeria lotungensis, endangered species, plot investigation, associated plant, checklist
