Clonostylis Forbesii
''Clonostylis'' is a monotypic genus of flowering plant in the family Euphorbiaceae. The sole species is ''Clonostylis forbesii'' is a flowering tree found in Sumatra. It has small glabrous leaves with an elliptic shape, arranged spirally. Taxonomy It was previously thought that ''Clonostylis'' S.Moore was a synonym of ''Spathiostemon'' Blume, but now ''Clonostylis'' is provisionally treated as a monotypic genus. Since only one specimen has been found, according to the Nationaal Herbarium Nederland, and it did not exhibit fruit or staminate flowers, a more definite classification is not yet possible. (The species is unisexual, and the specimen in question had only pistillate Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' ... flowers.) References * Welzen, P.C. van. 1998. ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...
