The Bryophyta s.l. are a proposed taxonomic division containing three groups of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses. Bryophyta s.s. consists of the mosses only. They are characteristically limited in size and prefer moist habitats although they can survive in drier environments. The bryophytes consist of about 20,000 plant species.

The United States National Herbarium was founded in 1848, when the first collections were accessioned from the United States Exploring Expedition (50,000 specimens of 10,000 species).

The Consortium of North American Bryophyte Herbaria (CNABH) was created to serve as a gateway to distributed data resources of interest to the taxonomic and environmental research community in North America. Through a common web interface, we offer tools to locate, access and work with a variety of data, starting with searching databased herbarium records.

In angiosperms, the receptacle or torus (an older term is thalamus, as in Thalamiflorae) is the thickened part of a stem (pedicel) from which the flower organs grow. In some accessory fruits, for example the pome and strawberry, the receptacle gives rise to the edible part of the fruit.The fruit of Rubus species is a cluster of drupelets on top of a conical receptacle.

Nov 30, 2020 · As a type of Bryophyte, moss is a spore-producing nonvascular plant. Because vascular systems help plants stay rigid and grow upright, moss is typically very small and stays low to the ground. In addition, moss gets its water and nutrients by absorbing everything directly through its leaves, unlike vascular plants which have roots ...

In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit.The peduncle sometimes has bracts (a type of cataphylls) at nodes.The main axis of an inflorescence above the peduncle is the rachis.There are no flowers on the peduncle but there are flowers on the rachis.

Jul 19, 2018 · Conclusion. Bryophytes are an informal division that consists of 3 groups of non-vascular plants, namely mosses, liverworts, and hornworts. Prominent bryophytes characteristics are the absence of true roots stems and leaves.

Nov 01, 2022 · The BBS Field Guide. This book is the only up-to-date, user-friendly guide to identifying British and Irish bryophytes in the field, with colour photos and drawings showing what species look like; notes on how to identify and to distinguish between similar species; and distribution maps and habitat notes, which will help you to decide whether you have correctly …

[excessive citations] The bryophyte division itself contains three (former) divisions: Bryophyta (mosses), Marchantiophyta (liverworts) and ... Individual plants 20–30 cm (8–12 in) or more long are common in Sphagnum species for example. But even aquatic species of moss and other bryophytes needs their mature capsules to be exposed to air ...
