Johnstonii

Johnstonii is a taxonomic epithet that can refer to several different species across various biological kingdoms, most commonly within the animal kingdom. It is often used to honor individuals named Johnston or Johnstone. For example, Johnston's chameleon (Trioceros johnstoni) is a species of chameleon found in East Africa, known for its distinctive cranial ornamentation. In entomology, several insect species bear the specific epithet johnstonii, signifying their discovery or description by someone with that surname, or in honor of a person named Johnston. Similarly, in botany, certain plant species may be classified as johnstonii, again typically as a tribute. The precise meaning of "johnstonii" in a scientific context is therefore dependent on the genus and family to which it is applied. Without further context, such as the organism's scientific name, it is impossible to determine which specific entity is being referenced. Further research into the taxonomic classification of the organism in question is necessary to identify the particular species or subspecies.
