Multiple paternity (polyandry) frequently occurs in flowering plants and animals and is assumed to have an important function in the evolution of reproductive traits. Polyandry in bryophytes may occur ...

Occasionally, friends have asked me about the life cycles of plants, so here I will attempt to summarize them, in the context of plant evolution. I set the stage by describing the basic pattern of ...

Clubmosses are not true mosses — they are the oldest group of vascular plants, which evolved 410 million years ago and ...

A new special issue of Applications in Plant Sciences, “Methodologies in Gametophyte Biology,” highlights an often overlooked aspect of the botanical world. A collection of 15 articles describes ...

A major question in evolutionary biology is how mating patterns affect the fitness of offspring. However, in animals and seed plants it is virtually impossible to investigate the effects of specific ...

This film explores the evolution of vascular plants, particularly ferns, through the study of ancient plant fossils. It highlights the anatomical features and adaptations that allowed early plants to ...

A seed consists of an embryo with a packet of nutrition (usually), all housed in a protective coat. They range in size from the dust-like seeds of orchids to coconuts. And they all trace their origin ...
