| Some botanists in the past recognised 1000 or more species, many of which are apomictic microspecies. |
| Mutations of these hybrids may have given rise to further microspecies stabilized by apomixis. |
| Yes, subspecies can be included, however the inclusion of varieties and microspecies is a decision for the national IPA team. |
| Blackberries belong to any of hundreds of microspecies of the Rubus fruticosus species aggregate. |
| Moreover, some controversy exists about the use of microscopic or macroscopic constants to calculate the relative concentration of each microspecies. |
| For example, with hybridisation, in a species complex of hundreds of similar microspecies, or in a ring species, the boundaries between closely related species become unclear. |
