The leaf traits, such as leaf anatomy, photosynthesis, leaf life span, and leaf element content were especially compared between Cypripedium and Paphiopedium, both belong to Cypripediodeae. The results suggest that the differences in leaf traits between Cypripedium and Paphiopedilum reflect their adaptation to contrasting habitats and are shaped by both phylogeny and environment.

The relationship between mycorrhizal fungi and orchids including Cypripedium, Paphiopedilum and Dendrobium were studied. The phylogenetic analysis revealed for the first time that mycorrhizal fungi in Paphiopedilum were members of the fungal family Tulasnellaceae, just the same as that in Cypripedium, having strong specificity. Different species of Cypripedium or Paphiopedium with similar habitats might have some identical mycorrhizal fungi, but the dominant mycorrhizal fungi for each orchid species were not the same. The dominant fungi are determined by the species and habitats.
