Rare earths: Botany meets geopolitics
The post discusses He et al., 2025’s work with Blechnum orientale, a fern that accumulates rare earth elements (REEs), in particular the mineral monazite. This discovery raises important questions about plants being a sustainable source for REEs. The post also provides background to REEs, and doesn’t ignore their geopolitical significance.

A botanical conundrum solved (sort of…)
The post follows-up on a previous post that considered how much of the plant’s photosynthesis is used in root mucilage production. In particular it discusses the challenges in verifying % claims from Wikipedia and McNear Jr. Mr P Cuttings emphasises careful source citation and acknowledges that the puzzle remains unresolved.

The wooden universal Australian
Eucalyptus by Stephen D Hopper uniquely integrates Aboriginal and Western scientific perspectives on eucalypts, offering insights into their cultural significance and ecological roles. The book includes first-hand accounts of Aboriginal practices and contrasts them with European views, emphasizing eucalypts’ importance and advocating for their conservation amid modern threats.

A botanical conundrum: HELP, please!
The post discusses the substantial – but source-substantiated – amount of energy plants use secreting root mucilage, estimated at 10-40% of their photosynthesized carbon. Mr P Cuttings expresses scepticism about these high figures, noting lower estimates from earlier studies. To clarify this discrepancy, a full copy of Newman’s 1985 article…

The domestication of people by plants…
Robert N. Spengler III’s “Nature’s greatest success” challenges the traditional view of agriculture’s origins, arguing that domestication was not a conscious act by humans but rather an inevitable outcome of plants’ evolution. He emphasises the partnership between plants and people, prompting critical thinking about our agricultural history and the role…

A deep dive into seaweed structural colour
Investigating the tips of the red seaweed Asparagopsis taxiformis, Hiroshi Kawai & Taizo Motomura identified presence of ‘nanospheres’. The structural colours of blue or white produced by the nanospheres are interpreted as examples of ‘warning colouration’, and ‘camouflage’, respectively.

When is a tree not a tree? When it’s a rock(!)
By way of an introduction to “ergastic substances” in plants, Mr P Cuttings considers calcium oxalate and carbonate. And relates this to a report that certain fig trees can sequester such inorganic carbon, potentially maintaining carbon sinks post-death. This biomineralisation could help to mitigate climate change while also benefiting soil…

Tomato or potato, which came first?
This post explores the evolutionary and historical relationship between potatoes and tomatoes, both members of the nightshade family. It briefly discusses their introduction to Europe via the Columbian Exchange, and notes contradictory claims about which arrived first. It then considers the pivotal role of tomato in the development of tubers…

A sceptical look at plants
Tim Entwisle’s “The sceptical botanist” is a highly readable collection of essays that address plant-related questions. While the book provides engaging insights, it sometimes lacks sufficient evidence for some of its statements. However, overall, it combines entertaining writing with educational value, appealing to both novice and seasoned botanists.
