The Great Freeze

One of the greatest threats to a herbarium is insects, which can infest the cabinets and eat specimens. Beetles, such as the cigarette beetle (Lasioderma sp), target asters and roses, demolishing flowers which are so important to identification. Other pests

Sewanee’s Basal Angiospems

There are several groups of angiosperms – flowering plants – that branched off from the phylogenetic tree earlier than did monocots or eudicots. They possess characteristics of both groups, and they are commonly known as basal angiosperms. Further genetic work is
