Question: Which genus has more species Sarracenia or Eulophia ?

Context paragraphs:
Eulophia: Eulophia is a genus of approximately 165 species of orchids.  It was first described by John Lindley in 1821.  The name "Eulophia" was derived from the Greek words "eu" (well) and "lophos" (plume), referring to the crested ridges of the labellum (lip) in most species.  This genus is abbreviated Eupha in horticultural trade.

Sarracenia rosea: Sarracenia rosea is a species of pitcher plant in the genus "Sarracenia" and is sometimes known as Burk's southern pitcherplant.

Eulophia guineensis: Eulophia guineensis is a species of orchid.  It is the type species of the genus "Eulophia" and is commonly known as the Guinea Eulophia or the broad-Leaved ground orchid.  It is found in the Cape Verde Islands, much of tropical Africa and part of the Arabian Peninsula.  It is a terrestrial orchid that can grow to a metre or so tall, and is found in lowland and upland woods and scrubland.

Orthochilus: Orthochilus is a genus of orchids that consists of at least 34 species, most of which are native to Africa and Madagascar with a few species in tropical and subtropical America.  The genus was first formally described in 1850 by the French botanist Achille Richard, who cited an earlier suggestion by the German botanist Christian Ferdinand Friedrich Hochstetter.  Richard recognized a single species, "Orthochilus abyssinicus", and noted that the genus shared many features with the closely related genus "Eulophia", but differed from it in the form of the pollen masses and caudicule, a stalk to which the pollen masses are attached.  The genus "Orthochilus" has often been viewed as a synonym of the larger genus "Eulophia" by many botanists, but a recent molecular phylogeny published in 2014 revealed that "Eulophia", as traditionally circumscribed, was paraphyletic unless "Orthochilus" was recognized as a separate genus.

Sarracenia: Sarracenia ( or ) is a genus comprising 8 to 11 species of North American pitcher plants, commonly called trumpet pitchers.  The genus belongs to the family Sarraceniaceae, which also contain the closely allied genera "Darlingtonia" and "Heliamphora".

Oeceoclades calcarata: Oeceoclades calcarata is a terrestrial orchid species in the genus "Oeceoclades" that is endemic to Madagascar.  It was first described by the British botanist Robert Allen Rolfe in 1905 as "Eulophia paniculata".  The German botanist Rudolf Schlechter later described this species as "Cymbidium calcaratum" in 1915 and then transferred his own taxon to the genus "Eulophia" (as "E. calcarata") in 1925.  When Leslie Andrew Garay and Peter Taylor revised the genus "Oeceoclades" in 1976, they transferred this species to the expanded "Oeceoclades" as "O. calcarata" because even though "Eulophia paniculata" was the older name and thus had priority, there had already been an earlier species named "Oeceoclades paniculata" (so named by John Lindley and now recognized as a species in the genus "Robiquetia") that prevented using that specific epithet.

Oeceoclades perrieri: Oeceoclades perrieri is a terrestrial orchid species in the genus "Oeceoclades" that is native to Mozambique and northwestern Madagascar.  It was first described by the German botanist Rudolf Schlechter in 1913 as "Eulophia ambongensis".  Schlechter had also described a separate species, "Eulophidium ambongense" in the same 1913 work.  When Leslie Andrew Garay and Peter Taylor resurrected and revised the genus "Oeceoclades" in 1976, these two taxa caused a naming conflict, so they chose to use "Eulophidium ambongense" as the basionym for "O. ambongensis" and reduced "Eulophia ambongensis" to a synonym of "O. perrieri", which was based on the basionym "Eulophidium perrieri" that Schlechter had also described later in 1925.  Both "Eulophidium perrieri" and "Eulophia ambongensis" were conspecific, belonging to the same species, so Garay and Taylor were free to use the later name as the base for their new combination when transferring taxa to "Oeceoclades".  Garay and Taylor noted that this species is related to "O. quadriloba", "O. sclerophylla", and "O. analavelensis" but can be distinguished from them by its characteristic long strap-like leaves that taper to a point.

Oeceoclades lonchophylla: Oeceoclades lonchophylla is a terrestrial orchid species in the genus "Oeceoclades" that is native to Tanzania, Mozambique, KwaZulu-Natal in South Africa, and Comoros.  It was first described by the German botanist Heinrich Gustav Reichenbach in 1885 as "Eulophia lonchophylla", then moved to the genus "Eulophidium" by Rudolf Schlechter in 1925 and to the genus "Lissochilus" by Joseph Marie Henry Alfred Perrier de la Bâthie in 1941.  It was last transferred to the genus "Oeceoclades" in 1976 by Leslie Andrew Garay and Peter Taylor.  Garay and Taylor also reduced the species "Eulophia tainioides" to a synonym of "O. lonchophylla" for lack of distinguishing characteristics that could separate the two species.

Sarracenia oreophila: Sarracenia oreophila, also known as the green pitcherplant, is a carnivorous plant in the genus "Sarracenia".  It has highly modified leaves in the form of pitchers that act as pitfall traps for prey.  The narrow pitcher leaves are tapered tubes that rise up to 75 centimetres from the ground, with a mouth 6 to 10 centimetres in circumference Like all the "Sarracenia", it is native to the New World.  "Sarracenia oreophila" is the most endangered of all "Sarracenia" species, its range limited to a handful of sites in northern Alabama, North Carolina, Georgia, and—historically--Tennessee.

Oeceoclades lanceata: Oeceoclades lanceata is a terrestrial orchid species in the genus "Oeceoclades" that is endemic to central Madagascar.  The flowers are rose-colored.  It was first described by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1935 as "Eulophia lanceata".  Perrier then later reduced the species to a synonym of "Eulophia pandurata" (now "Oeceoclades pandurata").  The species was resurrected and transferred to the genus "Oeceoclades" in 1976 by Leslie Andrew Garay and Peter Taylor, who argued that "O. lanceata" and "O. pandurata" are distinct with regard to their floral structure and shape of the labellum.  Garay and Taylor noted that "O. lanceata" is similar in vegetative morphology to "O. seychellarum".
