Sprengel's book introduced a functional view, which would today be called ecology, and provided evidence that pollination was an organised process in which insects acted as "living brushes" in a symbiotic relationship for the teleological purpose of fertilising the flowers. His discovery enabled him to understand the construction and ...
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 ...
ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
They are herbaceous plants which grow from a conical corm1–2.5 cm (1 ⁄ 2 –1 in) diameter, which sends up a tuft of narrow leaves 10–30 cm (4–12 in) long, and a sparsely branched stem 10–40 cm (4–16 in) tall bearing a few leaves and a loose one-sided spike of flowers with six petals.
A study of the evolution of volatile chemicals in scarab beetles and flowers that attract them in the family Araceae showed that the insects had evolved the chemicals in the Jurassic Period while the plants evolved the attractants later in the Cretaceous Period. [16] The colours of flowers are another area of enquiry.

Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants.It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactaceae, and Polygonaceae. [1]
Leucojum species are much larger and flower in spring (or early summer, depending on the species), with all six tepals in the flower being the same size, although some "poculiform" (goblet- or cup-shaped) Galanthus species may have inner segments similar in shape and length to the outer ones. Galantheae are likely to have arisen in the Caucusus.
