Question: which has more species Angraecum or Aphelandra?
Context: Angraecum penzigianum is a species of comet orchid that is endemic to Madagascar, and is recorded from Antsiranana, Fianarantsoa and Toamasina provinces, from elevations of 1,000–2,000 m.  It is an epiphytic perennial which grows in mossy forests.  It was previously thought to be endemic to the Andringitra Massif.  It is threatened by slash-and-burn cultivation, cattle grazing, charcoal production and bush fires. Angraecum germinyanum is a species of orchid.  This species is found in Madagascar with a waxy flower occurring in spring and summer. Angraecum pungens is a species of comet orchid that can be found in Cameroon, the Democratic Republic of the Congo, Equatorial Guinea, Gabon and Nigeria.  It is found in dense lowland forests, downstream from waterfalls, and on periodically-flooded marshes with "Oxystigma mannii", between elevations of 50–1,800 m.  It also occurs on "Terminalia catappa".  It is threatened by habitat loss from agriculture and logging. Aphelandra is a genus of about 170 species of flowering plants in the family Acanthaceae, native to tropical regions of the Americas. Angraecum subulatum is a species of comet orchid that can be found in Cameroon, the Democratic Republic of the Congo, Côte d'Ivoire, Equatorial Guinea, Gabon, Ghana, Guinea, Liberia, Nigeria and Sierra Leone.  This species is found in lowland forests, especially those rich in Caesalpinioideae between 50 and 700 m elevation.  It occurs in periodically-inundated swampy forests with "Raphia", "Pandanus" and Marantaceae, and on calcareous rock in shrubby vegetation.  It has been recorded on high shaded branches of "Gilbertiodendron dewevrei". Angraecum podochiloides is a species of comet orchid that can be found in Cameroon, the Democratic Republic of the Congo, Côte d'Ivoire, Equatorial Guinea, Gabon, Ghana, Liberia and Nigeria.  It can be found in dense lowland forests on "Gilbertiodendron dewevrei", and in humid forests at higher elevations or low montane forests.  It is an epiphyte on "Dialium corbisieri" or in periodically-flooded marshes with "Guibourtia". The genus Angraecum, abbreviated as Angcm in horticultural trade, common name Angrek (Indonesian and Malay) or Comet Orchid, contains about 220 species. Angraecum cadetii is a species of orchid endemic to Mauritius and Réunion.  It was named after botanist Thérésien Cadet.  It is the only known flower known to be pollinated by a cricket, specifically by a species of raspy cricket: "Glomeremus orchidophilus". Aphelandra sinclairiana Nees ex Benth.  is a plant species common called "Coral Aphelandra," "orange shrimp plant" or "Panama Queen."  It is a shrub up to 3 m (10 feet) high, native to Central America.  It has been reported from Panama, Costa Rica, Honduras and Nicaragua.  It is also cultivated in warm locations elsewhere, with pink, red, orange, or red-violet flowers and bracts. Oeceoclades maculata, sometimes known as the monk orchid or African spotted orchid, is a terrestrial orchid species in the genus "Oeceoclades" that is native to tropical Africa and now naturalized in South and Central America, the Caribbean, and Florida in North America.  It was first described by the English botanist John Lindley as "Angraecum maculatum" in 1821 based on a specimen collected from South America.  Lindley later revised his original placement and moved the species to the genus "Oeceoclades" in 1833.
