FAQs - Frequently Asked Questions
Q. Who is Joseph F. Rock?
Ans. Joseph Rock arrived to Honolulu in 1907 at the age of 23, where he became the Territory’s first botanist. He was appointed as UH (College of Agriculture) faculty in 1911 and was responsible for creating the first university herbarium. He served as the curator from 1911-1920, and quickly became an authority on the local flora. His botanical knowledge was largely self-taught, nevertheless, Rock's contributions to Hawaiian botany were significant.
Q. What is a herbarium?
A herbarium is a collection of preserved plants stored, catalogued, and arranged systematically for study by professionals and amateurs from many walks of life.
Q. Are herbarium new libraries?
A herbarium is a collection of dried plant specimens, which
are used for scientific study and as a reference collection
of named plants. The
practice of pressing plants between sheets of paper and drying
them is 500 years old. Thanks to this simple technique, most
of the characteristics of living plants are visible on the
dried plant. The few that are not (e.g. flower colour, scent,
height of a tree, vegetation type, etc.) are put on the label
by the collector.

|Note: Considering the more
than 3,240 herbaria in 165 countries throughout the world,
specimens are housed worldwide.
Herbaria are often closely linked to historic archives and libraries. Botanists often need
to consult specimens and reference books of floras at the same
time. Much of the literature is out of print but it is increasingly
becoming digitized. Below is a list of useful taxonomic web sites.
