Modern botanists have revisited sites examined by Alexander von Humboldt. Have modern advances made the German polymath's work irrelevant?

Glorious global gambol through the plants
Around the World in 80 Plants by Jonathan Drori 2021. Laurence King Publishing Ltd. In my review of Jonathan Drori’s Around the World in 80 Trees [‘80 Trees’], I suggested there were many more tree species worthy of...
“Mythical” Jurassic angiosperms perhaps not so mythical
Modelling that accounts for an incomplete fossil record doesn’t reject a pre-Cretaceous origin.

A new spin on Darwin’s “abominable mystery”
Darwin may indeed not have been referring to angiosperms broadly in his famous words to his friend.
Scientists suggest bringing a fresh set of eyes to the problem, ‘When did the first flowers evolve?’
A disagreement on when flowers evolved could be solved by studying the real experts on pollination, the pollinators.

Ovule and seed production patterns in relation to flower size and floral symmetry
Animal pollinated flowers show two types of floral symmetry, actinomorphy (radial symmetry) with several planes of symmetry or zygomorphy (bilateral symmetry) with just one symmetry plane. Although these floral types...

What happens when plants dominate lakes?
What is life like in a lake? Is it much like life on the shore, but wetter? Or are the environmental challenges significantly different?
Patterns of sex expression, health and mortality in a sex-changing tree
The ability of individuals to change sex during their lifetime is known as environmental sex determination (ESD). This ability represents a unique life history trait, allowing plants to allocate resources differentially...

When did the first flowers open?
Finding out when the earliest ancestor of the flowering plants evolved has been difficult. Estimates have been wildly different, depending on the method you use.
Thirty clues to the exceptional diversification of flowering plants
As angiosperms became one of the megadiverse groups of macroscopic eukaryotes, they forged modern ecosystems and promoted the evolution of extant terrestrial biota. Unequal distribution of species among lineages...
Cell cycle duration in the root apical meristem (RAM) of angiosperms
In plant studies it is essential to determine cell cycle duration (T). Zhukovskaya et al. have previously proposed an exponential model evaluating T in the root apical meristem (RAM) based on the dynamics of root...
Unexpected flowers in the Jurassic
Did flowering plants appear earlier than the fossil record indicates? Two papers independently conclude they did - and suggest what fossil evidence we should look for.
Integrative approaches to understanding angiosperm origins and diversity
The rise of angiosperms should be studied as part of the global increase in biodiversity.
