Wood anatomy recap: vessels vs tracheids

Turgor pressure, negative pressure, vessels and tracheids, embolisms… It’s a fact-packed Christmas Day episode of Completely Arbortrary, featuring the Oyster Bay-pine (Callitris rhomboidea). This drought tolerant tree has a surprising mechanism for keeping its water closely guarded. Merry Christmas!

Completely Arbortrary is produced and hosted by Casey Clapp and Alex Crowson
