In a vascular plant, the stele is the central part of the root or stem [1] containing the tissues derived from the procambium. These include vascular tissue, in some cases ground tissue and a pericycle, which, if present, defines the outermost boundary of the stele.
Selaginella canaliculata Selaginella selaginoides Selaginella willdenowii is known for its iridescent colours. There are about 750 known species of Selaginella. [21] They show a wide range of characters; the genus is overdue for a revision which might include subdivision into several genera. [citation needed] Species of spikemoss include:
Selaginella moellendorffii is a lycophyte that is an important model organism, especially in comparative genomics. S. moellendorffii is a member of an ancient vascular plant lineage that first appeared in the fossil record some 400 million years ago. They would later form a dominant part of the world's flora during the Carboniferous period.
They are defined by two synapomorphies: lateral rather than terminal sporangia (often kidney-shaped or reniform), and exarch protosteles, in which the protoxylem is outside the metaxylem rather than vice versa.
Selaginella selaginoides is a non-flowering plant of the spikemoss genus Selaginella with a wide distribution around the Northern Hemisphere. It resembles a moss in appearance but is a vascular plant belonging to the division Lycopodiophyta .
A fruiting body of the species Protostelium mycophaga. Protosteloid amoebae are typically found on dead plant matter, including stems and leaves of herbaceous plants, stems and leaves of grasses, bark of living trees, decaying wood and other types of dead plant matter. [8]
Contaminated food is causing a growing number of illnesses in the United States, and severe cases that lead to hospitalization or death are becoming more common. There were about 300 food recalls ...
Selaginella stellata, also recognized by its common name, starry spikemoss [1] or starry spike-moss, is a species of spikemoss of the family Selaginellaceae. It is a type of lycopod that grows naturally in Mexico and Central American countries like Guatemala and Belize [ 2 ] and can also be found in the state of Hawaii .
