Persistence is the retention of plant organs, such as flowers, seeds, or leaves, after their normal function has been completed, in contrast with the shedding of deciduous organs after their purpose has been fulfilled. [1] Absence or presence of persistent plant organs can be a helpful clue in plant identification, and may be one of many types ...
Lysimachia latifolia (broadleaf starflower) is a perennial herbaceous plant of the ground layer of forests in western North America. Herbaceous plants are vascular plants that have no persistent woody stems above ground. [1] [2] This broad category of plants includes many perennials, and nearly all annuals and biennials. [3]
P-persistent This approach lies between the 1-persistent and non-persistent CSMA access modes. [1] When the transmitting node is ready to transmit data, it senses the transmission medium for idle or busy. If idle, then it transmits immediately. If busy, then it senses the transmission medium continuously until it becomes idle, then transmits ...
In phylogenetic nomenclature, the Pentapetalae are a large group of eudicots that were informally referred to as the "core eudicots" in some papers on angiosperm phylogenetics. [2] They comprise an extremely large and diverse group accounting for about 65% of the species richness of the angiosperms , with wide variability in habit , morphology ...
In many cases more than one seral stage evolves until climax conditions are attained. [1] A prisere is a collection of seres making up the development of an area from non-vegetated surfaces to a climax community. A seral community is the name given to each group of plants within the succession.
This study recovered a group of rosids unlike any group found in any previous system of plant classification. To make a clear break with classification systems being used at that time, the Angiosperm Phylogeny Group resurrected Hutchinson's name, though his concept of Malpighiales included much of what is now in Celastrales and Oxalidales.

This article lists the living orders of the Viridiplantae, based primarily on the work of Ruggiero et al. 2015. [1] Living order of Lycophytes and ferns are taken from Christenhusz et al. 2011b [2] and Pteridophyte Phylogeny Group. [3]
Nymphaea alba, from the Nymphaeales. The basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of Amborella (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody ...
