Several British news reports (including the BBC "Bleeding trees") describe trees issuing red blood-like liquid when cut.
Once the stuff of myth and legend, modern day eye-witnesses now catch on camera blood pumping from the trunks of trees.
This is linked to biblical accounts (Book of Ezra).
Have any of these instances been validated? Examined by reputable botanists and established as not likely to be hoaxes? I wouldn't expect tabloid speculation from the BBC, but have not found any corroborating sources.
Rjzi helpfully points out that dragon trees are known for red sap. However, but the video is not exclusively about dragon trees (indeed, they're not mentioned). Yews are specifically mentioned, and unnamed trees in Australia with rough bark that does not seem to match the dragon tree. My question is, are there reputable accounts of trees not known for having red sap nevertheless appearing to bleed. E.g., perhaps there's a fungus known to gives tree sap a red color?
