Phloeoterma (/flɔɪ.*ɔtʌrmə/) is a botanical term that refers to the thin layer of tissue that covers the outer portion of tree bark. The word is spelled with a combination of Greek and Latin roots: 'phloe' meaning bark and 'terma' meaning covering. The asterisk in the IPA transcription indicates a syllable break between 'flɔɪ' and 'ɔtʌrmə'. The word is often used by botanists and arborists to describe the protective layer that shields trees from environmental stressors and insect damage.
