lycopod वाक्य

For the most recent classification of ferns and the Lycopods of Lycopodiophyta, see : Christenhusz and Chase ( 2014 ).
The basal chromosome count for this genus is " n = 23 ", which is distinctively different from other lycopods.
It is exceptional due to its preservation of several different clades of plants, from mosses and lycopods to more unusual, problematic forms.
It is the only definitively identified embolomere from the Joggins Fossil Cliffs and is the largest tetrapod to have been found preserved in lycopod tree stumps.
"Sigillaria ", like many ancient lycopods, had a relatively short life cycle-growing rapidly and reaching maturity in a few years.

The rhyniophytes bore fine rhizoids, and the trimerophytes and herbaceous lycopods of the chert bore root-like structure penetrating a few centimetres into the soil.
Unusually for the lycopods, which generally have microphylls with a single unbranched vein, the microphylls of " Selaginella " species contain a branched vascular trace.
It is a type of lycopod that grows naturally in Mexico and Central American countries like Guatemala and Belize and can also be found in the state of Hawaii.
Immediately above the Permian-Triassic boundary the glossopteris flora was suddenly largely displaced by an Australia-wide coniferous flora containing few species with a lycopod herbaceous under story.
Roots and root-like structures became increasingly more common and deeper penetrating during the Devonian, with lycopod trees forming roots around 20 cm long during the Eifelian and Givetian.
