The herbarium is a collection of preserved plants that are stored, catalogued, and arranged systematically for study. It does not carry information on plant height. Herbarium specimens carry a label which includes information about the plant specimen like the location from where the plant was collected, name of collector and the date on which it was collected. Details about its appearance, habitatis also mentioned. Each herbarium specimen is assigned a unique accession number, which functions like the catalog number of a book in a library. So, the correct answer is 'height of the plant'.
