'''''Ponerorchis''''' is a genus of Asian terrestrial tuberous orchids (family ]). It is native to temperate Eurasia, from Poland to Japan, to the north of the ] and to northern ].<ref name=WCSP_163253/> | |||

They can be found in evergreen forests and meadows in temperate, mountainous regions. The species ''Ponerorchis chidorii'', endemic to Japan, is also known to grow ].{{citation needed}} | |||
In the horticultural trade, this genus is abbreviated as "Pnr". A wide range of mostly ]s of ''Ponerorchis graminifolia'' are in cultivation, but are rarely grown outside Japan.{{citation neeeded}} | |||
==Description== | |||
''Ponerorchis'' species grow from an ovoid ]. They are slender plants with one to three usually slightly fleshy leaves. The flowers are all borne on the same side of the stem. The upper ] and the two lateral ]s form a hood. The ] is short and has obvious side appendages. There is a ] separating the ] from the ].<ref name=JinJinSchuLi14/> | |||
The genus was substantially expanded in 2014, so older descriptions do not necessarily apply to the revised genus. ''Ponerorchis'' was said to be differentiated from ''Amitostigma'' and ''Neottianthe'' by the presence of a bursicle or "sac" around the viscidium (a sticky pad at the base of the pollinium). However, this feature was found to be present in some species formerly assigned to ''Amitostigma'' and to be difficult to detect in some species of ''Ponerorchis''. In the expanded genus, a bursicle is present is some species and not in others.<ref name=JinJinSchuLi14/> | |||
==Taxonomy== | |||
===Phylogeny and classification=== | |||
The genus ''Ponerorchis'' was erected by ] in 1852 for the species '']''. ] studies between 1997 and 2003 showed that ''Ponerorchis'', when broadly defined, formed a ] with the genera ''Amitostigma'', ''Neottianthe'' and '']''. ''Ponerorchis'', as then ], was not ]. In 2003, in advance of further studies involving more species, ''Ponerorchis'' was broadened to include ''Chusua'', and an "orphan" species was transferred from ''Ponerorchis'' to become '']''.<ref name=BateHollPresLuo03/> A more detailed ] study in 2014 confirmed the strong relationship between ''Amitostigma'', ''Neottianthe'' and ''Ponerorchis'', whose species were mixed together in a single ], making none of the three genera ] as then ]. ''Amitostigma'' and ''Neottianthe'' were subsumed into ''Ponerorchis'',<ref name=JinJinSchuLi14/> making it a considerably larger genus. | |||
''Ponerorchis'' was previously distinguished from related genera by the presence of bursicles (pouchlike receptacles) enclosing the ]. The presence or absence of a bursicle was found not to be a useful diagnostic character, having arisen independently at least four times in the Orchideae.<ref name=JinJinSchuLi14/> | |||
''Ponerorchis'' is placed in the orchid subfamily ], tribe ], subtribe Orchidineae. After the genera were re-circumscribed as explained above, the relationship between ''Ponerorchis'' and the rest of the subtribe is as shown in the ] below.<ref name=JinJinSchuLi14/> | |||
