Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants. The smaller of these, the microspore, is male and the larger megaspore is female.

the whole fossil plant - and its evolution in time and space. From the second half of the 19th century (e.g., Ettingshausen 1866-1869, Engelhardt 1891,.

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). 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. The extensive bibliography of pertinent literature on which I have based my decisions should be helpful to persons interested in the classification of the dicotyledons. 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. The living Psilotaceae, the whisk-ferns, were sometimes added to the class, which was then usually called Psilopsida. This classification is no longer in use.

Evidence-based use of pharmaceutical drugs, often derived from medicinal plants, has largely replaced herbal treatments in modern health care. Pollen organ Telangiopsis sp., associated with but not attached to vegetative fronds, has been collected from the Upper Devonian (Famennian) Wutong Formation, Dongzhi County, Anhui Province, China. Hydrocharitaceae is a fully aquatic monocot family, consists of 18 genera with approximately 120 species. The family includes both fresh and marine aquatics and exhibits great diversity in form and habit including annual and perennial life… In 2018 barley accounts for only 5% of the cereal production worldwide, and regionally for up to 40% of cereal production.

The smaller of these, the microspore, is male and the larger megaspore is female. There are also some trees among the old lineages of flowering plants called basal angiosperms or paleodicots; these include Amborella, Magnolia, nutmeg and avocado, while trees such as bamboo, palms and bananas are monocots. They differ from seed plants (gymnosperms and angiosperms) in reproducing by means of spores and they lack flowers and seeds.

This is a tentative partial list of transitional fossils (fossil remains of groups that exhibits both "primitive" and derived traits).

In ancient Egypt, herbs are mentioned in Egyptian medical papyri, depicted in tomb illustrations, or on rare occasions found in medical jars containing trace amounts of herbs. Among the oldest, lengthiest, and most important medical papyri… Many of these groups contain some members that are no longer photosynthetic. Some retain plastids, but not chloroplasts, while others have lost plastids entirely. Evidence-based use of pharmaceutical drugs, often derived from medicinal plants, has largely replaced herbal treatments in modern health care.

Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, plants were treated as one of two kingdoms including all living things that were not animals, and all algae and fungi were treated…

This article records new taxa of plants that are were described during the year 2014, as well as other significant discoveries and events related to paleobotany that occurred in the year 2014. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. Over the course of the evolution of mammals, one bone from the lower and one from the upper jaw (the articular and quadrate bones) lost their purpose in the jaw joint and were put to new use in the middle ear, connecting to the existing… Modern phylogenetic analysis, back to 2001, demonstrated that horsetails belong firmly within the fern clade of vascular plants. Smith et al.

Fossils are abundant worldwide, especially in coal deposits.
