Enkianthus is a genus of shrubs or small trees in the heath family (Ericaceae).
 Its native range is in Asia, as far west as the eastern Himalayas, as far south as Indochina, and as far north and east as China and Japan.
Scadoxus puniceus, commonly known as the paintbrush lily, is a species of bulbous plant.
 It is native to much of southern and eastern Africa: Ethiopia, Sudan, Tanzania, Malawi, Mozambique, Zambia, Zimbabwe, Botswana, Swaziland, and South Africa (the Cape Provinces, KwaZulu-Natal, the Free State and the Northern Provinces).
 "Scadoxus puniceus" can be found in cool, shady habitat such as ravines and forests, where it is often found in moist leaf litter.
 Other common names include snake lily, royal paintbrush, King-of-Candida, African blood lily (English), rooikwas (Afrikaans), isisphompho, and umgola (Zulu).
 There are nine species of "Scadoxus" of which three, "S. puniceus", "S. multiflorus" (with 2 subspecies) and "S.membranaceus", occur in South Africa.
Scadoxus multiflorus (formerly "Haemanthus multiflorus") is a bulbous plant native to most of sub-Saharan Africa from Senegal to Somalia to South Africa.
 It is also native to Arabian Peninsula (Saudi Arabia, Yemen, Oman) and to the Seychelles.
 It is naturalized in Mexico and in the Chagos Archipelago.
 It is grown as an ornamental plant for its brilliantly coloured flowers, either in containers or in the ground in where the climate is suitable.
 There are three recognized subspecies.
 Strongly toxic like other "Scadoxus" species, it has been used as a component of arrow poisons and fishing poisons, as well as in traditional medicine.
 Common names, some of which are used for other species, include blood lily, ball lily, blood flower, Katherine-wheel, oxtongue lily, poison root and powderpuff lily.
Scadoxus nutans is a herbaceous plant endemic to southwest Ethiopia.
 Its red to pink flowers face downwards as the top of the flowering stem bends over, unlike any of the other species of "Scadoxus".
 It grows mainly as an epiphyte in tropical mountain forests, which are disappearing, making the species vulnerable to extinction.
 It is sometimes cultivated as an ornamental plant.
Scadoxus pseudocaulus is a herbaceous plant native to Nigeria, Equatorial Guinea, Cameroon and Gabon.
 Similar in many respects to "Scadoxus cinnabarinus", it is cultivated as an ornamental plant but has proved reluctant to flower.
Scadoxus cyrtanthiflorus is a herbaceous plant endemic to the Rwenzori Mountains of east tropical Africa.
 Unusually for the genus "Scadoxus" its tubular blooms are pendant.
 It is sometimes grown as an ornamental plant in heated greenhouses.
In mathematics, a 3-manifold is a space that locally looks like Euclidean 3-dimensional space.
 A 3-manifold can be thought of as a possible shape of the universe.
 Just as a sphere looks like a plane to a small enough observer, all 3-manifolds look like our universe does to a small enough observer.
 This is made more precise in the definition below.
Scadoxus pole-evansii, commonly known as the Inyanga fireball, is a herbaceous plant endemic to mountains in east Zimbabwe.
 It was only discovered for science in 1960.
 Similar in many respects to the more widely grown "Scadoxus multiflorus", it is cultivated as an ornamental plant.
Scadoxus is a genus of African and Arabian plants in the Amaryllis family, subfamily Amaryllidoideae.
 The English name "blood lily" is used for some of the species.
 The genus has close affinities with "Haemanthus."
 Species of "Scadoxus" are grown as ornamental plants for their brilliantly coloured flowers, either in containers or in the ground in frost-free climates.
 Although some species have been used in traditional medicine, they contain poisonous alkaloids.
Scadoxus membranaceus is a bulbous plant from South Africa (east Cape Province, KwaZulu-Natal).
 The smallest of the species of "Scadoxus", it is sometimes cultivated as an ornamental plant where a minimum temperature of 5 °C can be maintained.
