Vasculum

Vasculum is a tool used primarily in the field of botany. It is a rigid container used for the collection and transportation of plants. The vasculum is designed to keep plants in good condition during field trips, often for several days, until they can be transferred to a herbarium.

History

The vasculum has a long history in botany, dating back to the 18th century. It was first used by Carl Linnaeus, a Swedish botanist, physician, and zoologist, who formalised the modern system of naming organisms called binomial nomenclature. Linnaeus and his students used vascula (the plural of vasculum) extensively during their plant collection trips.

Design

The traditional design of a vasculum is a cylindrical or box-like shape, made from metal, with a hinged lid. The lid is typically secured with a clasp or latch. The inside of the vasculum is often divided into sections or compartments to keep different plant specimens separate. Some vascula also have straps or handles for easy carrying.

Usage

To use a vasculum, a botanist collects a plant specimen and places it inside the container. The plant is usually wrapped in a damp cloth or newspaper to keep it moist and prevent it from wilting. The vasculum is then closed and carried back to the herbarium or laboratory for further study.

Modern Variations

While the traditional metal vasculum is still in use today, there are also modern variations made from other materials, such as plastic. These are often lighter and more durable, making them more suitable for long field trips. Some modern vascula also have additional features, such as adjustable compartments or built-in hydration systems.
