Introduction. With approximately 13 species, the Bryophyta compose the second most diverse phylum of land plants. Mosses share with the Marchantiophyta and Anthocerotophyta a haplodiplobiontic life cycle that marks the shift from the haploid-dominated life cycle of the algal ancestors of embryophytes to the sporophyte-dominated life cycle of vascular by: Metzgeriales is an order of group is sometimes called the simple thalloid liverworts: "thalloid" because the members lack structures resembling stems or leaves, and "simple" because their tissues are thin and relatively species in the order have a small gametophyte stage and a smaller, relatively short-lived, spore-bearing : Jungermanniopsida. The phylogenetic history of and evolutionary trends within the simple thalloid liverworts (Jungermanniopsida, subclass Metzgeriidae) are reconstructed in a combined analysis of molecular and. Abstract. Experiments in which several antagonists of the synthesis of Hyp-containing proteins (Hyp-proteins) induced profound changes in the morphogenetic patterns exhibited by five different species of leafy liverworts led to a hypothesis that some of the Hyp-proteins had a morphoregulatory function (Basile , Basile and Basile ).The class to which the Cited by: 5.

These are small plants, no more than half an inch off the ground, that can be flat and ribbon-shaped or leafy. 4. Gametophores are erect leafy branches which develop on the protonema. 5. Gametophores can be branched or un-branched and can be differentiated into three parts-rhizoids, ‘stem’ and ‘leaves’. 6. Branches arise below the ‘leaves’. 7. ‘Leaves’ are with midrib, un-lobed and arranged spirally in three to eight rows on the axis or. 8.   Abstract. Plagiochila sect. Vagae is a large pantropical clade that is characterized morphologically by frequent terminal branching, vegetative distribution by propagules on the ventral surface of the leaves and a capsule wall with thickenings in all chila corrugata from Brazil is characterized by strongly undulate, toothed leaf margins and represents the only Cited by:

  Leaf morphology has been considered one of the most distinctive and stable features of genera and families in leafy liverworts, with some exceptions shown by Glenny et al. (). Particularly in species having multi-lobed leaves with ciliate lobes such as Telaranea, the morphology of the cilia and discs show significant variation at the Cited by: 7. Bakken, S.

() Phytosociology and Ecology of Cryptogamic by: Endogenous branches in Metzgeriaceae are reminiscent of those in leafy liverworts (Renzaglia, ). One of the most surprising results from the Davis (in press) analyses was the placement of Pleurozia in Metzgeriinae (simple thalloid II) rather than among the “true” leafy liverworts (Figs. 7, Cited by: Full text of "Structural botany, or, Organography on the basis of which is added the principles of taxonomy and phytography, and a glossary of botanical terms" See other formats.
