The Himalayan peony is a
Paeonia emodi is much alike P. sterniana, having white flowers with entirely yellow stamens, and segmented leaflets. P. emodi however is with up to 1 m much taller, has only one or rarely two carpels developing per flower which are softly hairy, has several flowers per stem, and ten to fifteen segments in each lower leaf, while in P. sterniana flowers are solitary, have two to four hairless carpels and the lower leaves consist of twenty to forty segments and lobes.[5][6] The seeds P. emodi ripen much later than those of P. sterniana, which are already shed in August.[7]
Taxonomy
Paeonia emodi was first mentioned in the Numerical List of dried specimens of plants in the East India Company's Museum: collected under the superintendence of Dr. Wallich of the Company's botanic garden at Calcutta of 1831. In 1834, John Forbes Royle validated this name by publishing a proper description of the taxon. Ernst Huth reduced the taxon to P. anomala var. emodi in 1891.[8] Joseph Dalton Hooker and Thomas Thomson distinguished a var. glabrata in the Flora of British India in 1875, a name that was to be reduced to f. glabrata by Hiroshi Hara in 1979. Recent authors do not recognise this taxon.[1] Paeonia sterniana is sometimes regarded as a subspecies of P. emodi.[9]
Etymology
Paeonia emodi takes its name from the Latin for Himalaya, emodi montes, where it grows in the western part of the mountain range.[10]
Distribution and habitat
This peony naturally occurs from Afghanistan and southern Tibet (Gyirong County), to western Nepal and grows at an altitude of 1800–2500 m in thickets.[11][5] P. emodi is found in deciduous forests of several oak species and Quercus floribunda, most often on south facing slopes. In Uttarakhand it occurs together with Impatiens thomsonii, I. sulcata, Erigeron multiradiatus, Viola canescens, Trifolium pratense, Pennisetum flaccidum, Murdannia divergens, Euphorbia peplus and Hemiphragma heterophyllum.[12]
Use
Paeonia emodi is used in traditional medicine in its home range to treat amongst others
