Abstract:
Four new records of Orchidaceae from Hunan are reported,Apostasia ramifera S. C. Chen et K. Y. Lang、Eria sinica(Lindl.) Lindl.、Gastrodia albidoides Y. H. Tan T. C. Hsu were collected from The Jiulongjiang National Forest Park in Rucheng County and Galeola faberi Roife was collected from Daweishan National Forest Park in Liuyang County. Apostasia is a new genus in Hunan province. The voucher specimens are preserved in CSFI. The distribution area of the four species of Orchidaceae newly discovered in Hunan are all have a larger span,it has a important value on the fl oristic studies of Orchidaceae. Orchidaceae is the essence of the forest,with a rich species diversity. But many species only have a tiny population,needing high requirementsin on the ecological environment. The Orchidaceae basically were raised in a primeval forest or on the rock suiface which were undisturbed. It is particularly important to protect the habitat of Orchidaceae. In this paper,we discussed the investigation and protection of orchidaceae in Hunan.Keywords:

Seven species were reported as new records of Jiangxi province, which collected from Wugongshan region, including Huperzia kunmingensis(Lycopodiaceae), Hydrangea mangshanensis(Saxifragaceae), Itea glutinosa(Saxifragaceae), Stellaria monosperma var. japonica(Lycopodiaceae), Youngia pratti(Compositae), and Calanthe henryi(Orchidaceae), Collabium formosanum(Orchidaceae). Among these species, H. kunmingensis, H. mangshanensis, I. glutinosa, Y. pratti and C. henryi are endemic in China. C. henryi is stenotopic distribution in China and regarded as vulnerable endangered plant by IUCN. The report is of great significance to the plant diversity and floristic composition in Jiangxi. All the specimens examined are preserved in Jishou University (JIU) and Sun yat-sen University (SYS).

Cymbidium lii (Orchidaceae: Epidedroideae: Cymbidiinae), endemic to Hainan, China and the only one well-developed rhizome epiphytic species ever found in the genus, is newly described. A detailed morphology comparison including the seed characters between the newly discovered orchid and the related species was conducted. A local palm, Livistona saribus (Lour.) Merr. ex A. Chev was found to be the unique host plant. It is considered to be critically endangered according to the latest IUCN Red List criteria.

Systematic researches on Orchidaceae in Shaanxi showed that Cyripedium tibeticum, Bulbuphyllum henanense and Platanthera mandarinorum are new distribution specties in the province. It is therefore concluded that there are 7 species of Cypripedium, 2 species of Bulbuphyllum and 4 species of Platanthera in Shaanxi.
