Unisexual, cone-like flowers (catkins) were considered to be primitive (alder, birch, etc.). This was the first major phylogenetic classification. This system is used today in many herbaria and floras and very useful for a modern taxonomist, but the concepts of what is primitive and advanced has changed today.
Where did the phylogenetic system come from?
The first phylogenetic systems came from Botanical Garden in Berlin. Engler and Prantl believed that the plant classification system should reflect the evolutionary history and their greatest work Die Naturlichen Pflanzenfamilien, adopted a system that proceeded from simple structures to complex.

What is the first classification of plants?
The first classification of plants is the non-vascular plants; As their name implies, nonvascular plants [1] lack vascular tissues that can help them transport water and nutrients. Nonvascular plants are considered to be the earliest living plants in the planet. However, fossils have not been found because these types of plants fossilized poorly. The most common non-vascular plants include the members of the Phylum Bryophyta and is described below.
What are the two major groups of plants?
In general, botanists group plants into two major groups: non-vascular and vascular. The former being composed of early plants while the latter consists of plants which had developed a vascular system.
What are vascular plants?
Also the next classification of plants is also known as the tracheophytes, vascular plants have been allowed by evolution to possess vascular tissues ( xylem and phloem) that aid them to transport water and minerals. All other plants like the members of the Phylum Pteridophyta, Gymnosperms, and Angiosperms are classified as vascular plants. The said plant phyla are described below.

Among all plant phyla, the members of the Phylum Bryophyta are considered the simplest. Regarding physical appearance, mosses are small and inconspicuous. Bryophytes lack vascular tissue and wood that can render them structural support. They also lack true leaves, stems, and roots that can help them transport water and nutrients. Because of this, they are limited to a narrow range of habitats.
What is the name of the plant that produces spores?
Pteridophytes [4] are seedless plants; being such, they are incapable of passing on their genetic material to their offspring using cones, fruits, or seeds. Instead, this classification of plants produces spores that are located on the underside of their leaves, known as sporophylls.

Natural System of Classification of Plants. A further increase in the list of recognized plants forced man to group plants according to their natural affinities. Grouping based on the natural affinities of plants were known as “Natural system of classification” The first such grouping was introduced by DE Jussieu.
How many classes of plants were there in the plant kingdom?
According to this system when an unknown plant was discovered it cloud be easily inserted among when those already known. The plant kingdom was divided into 25 classes by Linnaeus. One of Linnaeus classes CRYPTOGAMIA includes plants with concealed reproductive organs. Cryptogams were subdivided into four orders;
What is the Acotyledons classification?
In De Jussies classification of plants, the Acotyledons was almost equivalent to Linnaeus Cryptogamia. Besides these classifications many other systems were also proposed during first half of the nineteenth century, but they were all unsuitable for spore-producing (cryptogamin) plants.
Which is more advanced, a vascular plant or a bryophyte?
Vascular bearings plants are considered to be more advanced than bryophytes. Vascular plants can be spore bearing or seed bearing. Pteridophytes occupy the intermediate position between bryophytes and seed-bearing plants, i.e., gymnosperms and angiosperms.
Why did the classification of plants and other organisms change in the 1960s?
The opinion began to change in the 1960s, largely because of the knowledge gained by the biochemical and electro-microscope techniques. The techniques revealed fundamental affinities and differences on the subcellular level that encouraged a spate of new proposal for multiple-kingdom system. A number of proposals were made but the most acceptable was extended in 1959 by R.H. Whittaker. Whittaker classification of plants and other organisms were based on five kingdoms which owe’s a great debt to the four-kingdom system of Herbert F. Copeland from Sacramento City College, California, published in 1956 mentioned below:
What is the sexual system of Linnaeus?
The gradual recognition that the structure of the flower is of more fundamental importance in classification than are vegetative characters opened the gate for the “sexual system” of Linnaeus classification. Carl Linnaeus grouped plants according to the number of stamens and carpels, their union and their presence and absence in the flower. This system had the great benefits even for the unknown plants. According to this system when an unknown plant was discovered it cloud be easily inserted among when those already known. The plant kingdom was divided into 25 classes by Linnaeus.
