Which genus has more species, Eomecon or Epipactis?
Epipactis
Epipactis
Epipactis, or Helleborine, is a genus of terrestrial orchids consisting of approximately 70 species.
 This genus is abbreviated as Epcts in horticultural trade.
Eomecon
Eomecon is a monotypic genus of flowering plants in the poppy family containing the single species Eomecon chionantha.
 Its common names include snow-poppy and dawn-poppy.
 It is native to China.
Epipactis leptochila
Epipactis leptochila, the narrow-lipped helleborine, is a species of the genus "Epipactis".
 Found in chalk or limestone-based beech and hornbeam woodland in southern England, the orchids are also found with Birch and Alder trees in Scotland and the north of England.
 The narrow-lipped helleborine blooms from early June to mid-August.
 "Epipactis leptochila" is also found in parts of northern Europe (away from the coastline) but it is known for its presence in England.
 Due to woodland clearing, the orchids are becoming less common. Epipactis tremolsii
Epipactis tremolsii is a species of terrestrial orchid of the genus "Epipactis", belonging to the family Orchidaceae.
 It is confined to the western Mediterranean region where it grows in open mixed oak, cork oak and pine woodland.
 In Portugal in the Algarve region, it flowers rather earlier than "Epipactis helleborine" and can be found from April onwards – earlier in an early spring. Hacquetia epipactis
Hacquetia epipactis (syn.
 "Dondia epipactis" Spreng.
) is a species of flowering plant of the Apiaceae family, native to moist, shady woodland habitats in Europe.
 The only species of its genus, it is a rhizomatous, clump-forming herbaceous perennial, growing to about 30 cm in height, with glossy green leaves which only fully develop after flowering.
 The flowers, appearing late winter and early spring, consist of multiple tiny yellow florets framed by lime green bracts, and carried in dense spherical umbels 4 cm in diameter.
 It is easy to cultivate in Plant Hardiness Zones 5 to 7 according to the United States Department of Agriculture (though it is hardier than indicated and can be grown easily down to at least Zone 3), and looks best in a woodland setting which imitates its native habitat. Sanguinaria
Sanguinaria canadensis (bloodroot) is a perennial, herbaceous flowering plant native to eastern North America.
 It is the only species in the genus Sanguinaria, included in the family Papaveraceae, and most closely related to "Eomecon" of eastern Asia. Helleborine
Helleborine is the common name for a number of species of orchid.
 It does not correspond to any currently used taxonomic category.
 Some of the plants called helleborines are classified in the genus "Epipactis", some in genus "Cephalanthera".
 A genus "Helleborine" was formerly recognised but has now been absorbed into the Grass pink genus "Calapogon".
