All but one of the three living Larix laricina noted by Swinehart (1994) have died, and the Cypripedium
acaule noted by Lindsey in 1972 and Swinehart in 1993 were not observed, nor were the Lycopodium lucidulum and Lycopodium obscurum that Swinehart found in 1993.
Variation of photosynthetic capacity with leaf age in an alpine orchid, Cypripedium
Dryopteris cristata and Vaccinium macrocarpon are threatened, while Cypripedium
acaule, Glyceria taxa and Woodwardia virginica are of special concern (Table 3).
Contrasting allozyme diversity between northern and southern populations of Cypripedium
parviflorum (Orchidaceae): Implications for Pleistocene refugia and taxonomic boundaries.
Two kinds of biotic interactions, pollination and mycorrizae, play vital roles in orchid reproduction and survival, we therefore specifically look at the relationship between orchid pollination and conservation, using Cypripedium
(Bernhardt and Meier, this volume) and the diverse orchids in the Mediterranean region (Vereecken et al.

reginae in Axenic Culture.
For example, Yachang is one of the few places where Paphiopedilum, a genus of tropical lady's slipper orchids, co-occur with the temperate lady's slipper orchids, Cypripedium
A comparison of species belonging to the closely related genera Paphiopedilum and Cypripedium
in China reveals that they have different physiological adaptations and survival strategies (Hu Hong, unpublished data).
To better illustrate variation of rates of pollination and fruit set within a threatened/endangered lineage we propose to use species within the much-studied temperate genus, Cypripedium
, as a model system.
Other notable but more local herbaceous species include Carex trisperma, Coptis trifolia, Cypripedium
acaule, Dryopterus spinulosa, Isotria verticillata, Lycopodium lucidulum, L.
