Rhizopogonaceae are a family of fungi in the order Boletales.
 The family, first named and described by botanists Ernst Albert Gäumann and Carroll William Dodge in 1928, contains 2 genera and 151 species.
 The genus "Fevansia", formerly thought to belong in the Rhizopogonaceae, was found to belong in the Albatrellaceae in a molecular phylogenetics study.
Haemanthinae is a small subtribe of Haemantheae, and therefore within the African clades of Amaryllidoideae.
 It consists of two genera, "Haemanthus", and "Scadoxus".
Swainsonia is a genus of sea snails, marine gastropod mollusks in the family Mitridae.
The Stereopsidales are an order of fungi in the class Agaricomycetes.
 It was first described in 2014 to contain the genera "Stereopsis", which was until then classified in the order Polyporales, and "Clavulicium", which was until then classified in the order Cantharellales.
 Molecular phylogenetics analysis showed these two genera to belong together in their own order.
 This order might belong in the subclass Phallomycetidae, but this relationship was poorly supported.
 The Stereopsidales contain corticoid fungi ("Clavulicium" and "Stereopsis") and stalked, funnel shaped fungi ("Stereopsis").
 They are united by features of their spores, which have refractive contents, and become angular and amber-like as they dry.
 All known members also possess basidia with two sterigmata, although this is also a feature of fungi in many other orders.
Stixaceae is a family in the plant order Brassicales.
 It is no longer recognised by most taxonomists.
 The three genera formerly included in Stixaceae — "Forchhammeria", "Stixis" and "Tirania" — have sometimes been placed instead in the Capparaceae, but it is now clear that they do not belong there.
 It is unknown where they do belong though, so currently they are unplaced at family rank.
 In the APG IV system, the genera comprising Stixaceae are included in the family Resedaceae.
The Primulaceae are a family of herbaceous and woody flowering plants with about 53 genera with 2790 species, including some favorite garden plants and wildflowers, commonly known as the primrose family.
 Most Primulaceae are perennial though some species, such as scarlet pimpernel, are annuals.
 The family has been variously circumscribed, but it is now accepted in the broad sense including the former families Myrsinaceae and Theophrastaceae, because many genera traditionally placed in Primulaceae were found to belong to those other families and when united their circumscription remains intact.
The Megascolecidae are a large family of earthworms which has native representatives in Australia, New Zealand, both Southeast and East Asia, and North America.
 The most ancient lineages of the family show a Gondwanan distribution and have been used as evidence of continental drift.
 Members of the "Pheretima" group of genera (e.g. "Amynthas") are widely distributed around the tropics, much as some Lumbricidae are distributed through the temperate zones.
 Some North American native genera – e.g., "Arctiostrotus", "Argilophilus" and "Driloleirus" – also belong to this family.
Stereopsis is the sole genus of fungi in the family Stereopsidaceae.
 The genus was formerly placed in the family Meruliaceae in the order Polyporales but was found to belong in its own order along with the genus "Clavulicium".
 "Stereopsis" was circumscribed by English mycologist Derek Reid in 1965.
 It contains species that form funnel-shaped basidiocarps as well as the corticioid species "Stereopsis globosa" which was formerly considered a species of "Clavulicium".
 The species "Stereopsis humphreyi" and "Stereopsis vitellina" were found to belong in the Agaricales and Atheliales respectively in a molecular phylogenetics study, and because of this do not belong in "Stereopsis", but they have not yet been transferred to their own genera.
A sheep–goat hybrid (sometimes called a geep or shoat in popular media) is the hybrid offspring of a sheep and a goat.
 Although sheep and goats seem similar and can be mated, they belong to different genera in the subfamily Caprinae of the family Bovidae.
 Sheep belong to the genus "Ovis" and have 54 chromosomes, while goats belong to the genus "Capra" and have 60 chromosomes.
 The offspring of a sheep-goat pairing is generally stillborn.
 Despite widespread shared pasturing of goats and sheep, hybrids are very rare, indicating the genetic distance between the two species.
 Though sometimes called "geep", they are not to be confused with sheep–goat chimera, which are artificially created.
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.
