DENDROLOGY

Detailed explanation-1: -Lectotype : Designated as the type when no holotype was identified by the original author, or when the holotype is lost or destroyed. It is chosen from among the specimens available to the original publishing author.

Detailed explanation-2: -Neotype – a substitute specimen selected in special circumstances to replace the holotype after the species was first described and the original holotype has been lost or destroyed (e.g. fire, war etc.). Cotype – no longer used; formerly used for either syntype or paratype.

Detailed explanation-3: -Holotype and neotype are two kinds of type specimens. Holotype is a specimen designated by the original describer of the form, to be the single physical example of a species. Neotype is a specimen chosen when the available holotypes have been lost or destroyed.

Detailed explanation-4: -Syntypes are specimens cited by the author, when a holotype was not designated or has been lost.
