A container used by botanists when collecting plants, typically in the form of a flattened cylindrical metal case with a lengthwise opening, carried by a shoulder strap.
- ‘As a general rule it is as well that the microfungi as collected should be at once placed in the vasculum, so as to secure for them a certain amount of moisture until they can be examined at home.’
- ‘Several specimens may be placed in one vasculum, but be cautious to not damage delicate leaves and flowers.’
- ‘Many plants may be kept in the vasculum for several days if needed without sustaining injury.’
- ‘The plastic bag has universally replaced the vasculum, but care needs to be taken to protect from the sun.’
Late 18th century: from Latin, diminutive of vas vessel.
