The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
[64] [65] Meanwhile, in Switzerland, from 1554, Conrad Gessner (1516 – 1565) made regular explorations of the Swiss Alps from his native Zurich and discovered many new plants. He proposed that there were groups or genera of plants. He said that each genus was composed of many species and that these were defined by similar flowers and fruits.

Two years after Tärnström's expedition, Finnish-born Pehr Kalm set out as the second apostle to North America. There he spent two-and-a-half years studying the flora and fauna of Pennsylvania, New York, New Jersey and Canada. Linnaeus was overjoyed when Kalm returned, bringing back with him many pressed flowers and seeds.

The native flora of the United States includes about 17,000 species of vascular plants, plus tens of thousands of additional species of other plants and plant-like organisms such as algae, lichens and other fungi, and mosses.
Scientists studying fossils found in Spain say they may have found the world's 'first flower.' Kind of. Researchers were studying fossils of a freshwater plant species known as Montsechia vidalii ...
In the late 1980s, university researcher John Dole discovered the grafting method (grafting rarer densely-branched cultivars onto more common sparsely-branched cultivars) – previously known only to the Eckes – and published it. [41] This allowed competitors to flourish, particularly those using low-cost labor in Latin America. The Ecke ...
