Orchids exploit two broad types of habitats—terrestrial and epiphytic. Terrestrial orchids have their peren-nating tissues in the surface substrate of the ground, such as the soU or organic floor of a forest, or the surface sediment or peat of a wet meadow or bog. In contrast, epiphytic orchids use trees as a platform upon which to grow within the canopy. Epiphytic orchids do not obtain their moisture or nutrients from their host— they only use the tree as a physical substrate upon which to grow, either perched on a branch or as a climbing, vine-like plant. 

According to the shape of UV spectra and physico-chemical results, different types of waters can be identified. The northern part of the marsh (wet meadows, stations 5 and 6) is only influenced by freshwaters. UV spectra are typical of natural water without organic matter (the absorbance above 240 nm is close to zero). The Gaussian shape around 210 nm indicates the presence of nitrates. UV spectra are superposed, meaning that water quality is the same for these two stations. The conductivity value of 420 pSIcm shows the direct influence of the chalk aquifer.

Habitat In sub-alpine zones, in wet meadows in river valleys, and among junipers. Endemic to the Tian Shan and Pamiro-Alai mountains. 

Habitat The adyr and tan zones. In river valleys, along canals, in long-cultivated fields often found along ravines into the mountains, where it grows on stony slopes with rocky debris and in wet meadows. 

Habitat In steppes, in wet meadows in the forest-meadow mountain belt, along canals, in orchards, and in boggy places. 

Habitat On along rivers and in wet meadows, sometimes in water.

Waters of the United States—(1) All waters that are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters that are subject to the ebb and flow of the tide. (2) All interstate waters, including interstate wetlands. (3) All other waters such as interstate lakes, rivers, streams, mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation, or destruction of which would affect interstate or foreign commerce.
