The rhyniophytes are a group of extinct early vascular plants that are considered to be similar to the genus Rhynia, found in the Early Devonian (around 419 to 393 million years ago).

However, this comes at a price: while stomata are open to allow CO 2 to enter, water can evaporate. Water is lost much faster than CO 2 is absorbed, so plants need to replace it, and have developed systems to transport water from the moist…

Phylogenetic analysis shows the group branching off at the base of the evolution of vascular plants and they have a long evolutionary history. Fossils are abundant worldwide, especially in coal deposits.

While there he undertook studies of Indo-Malayan and Sikkim-Himalayan tropical vegetation, carried out botanical explorations, taught biology to troops and began work on his Botanical Latin. The earliest known fossils of flowers and flowering plants are from 130 million years ago, in the Lower Cretaceous. The flowering plants have long been assumed to have evolved from within the gymnosperms; but the known gymnosperms form a… Table V lists the geographical abbreviations used in the synopsis.

Background Cloud forests, characterized by a persistent, frequent or seasonal low-level cloud cover and fragmented distribution, are one of the most threatened habitats, especially in the Neotropics.

They differ from seed plants (gymnosperms and angiosperms) in reproducing by means of spores and they lack flowers and seeds. The vegetative (somatic) structures of vascular plants include two major organ systems: (1) a shoot system, composed of stems and leaves, and (2) a root system. They were among the first vascular plants in the fossil record, and had a world-wide distribution. They were probably stem-group lycophytes, forming a sister group to the ancestors of the living lycophytes. Other flowers have modified stamens that are petal-like; the double flowers of Peonies and Roses are mostly petaloid stamens. Flowers show great variation and plant scientists describe this variation in a systematic way to identify and… Matushevskaya, Aniela (2013).
