Short Answer
Orchids are a family of flowering plants classified in the Taxonomic Order Asparagales. They are classified in the family Orchidaceae, which is divided into five subfamilies: Apostasioideae, Cypripedioideae, Orchidoideae, Vanilloideae, and Epidendroideae. Within these subfamilies are over 25,000 different species of orchid, making them one of the most diverse and abundant flowering plant families in the world.
Overview of Orchid Taxonomy
Orchids are one of the most diverse and beautiful flowering plants in the world.
They come in a wide variety of shapes, sizes, and colors, which can make them difficult to classify.
To make sense of the vast number of species and varieties, botanists have developed a systematic taxonomic system for organizing orchid species into distinct categories.
At the top of the orchid taxonomy system is the division into two subfamilies: Epidendroideae and Pleurothallidinae. These two subfamilies are then further divided into genera and species. Each genus and species has its own unique characteristics, such as flower structure, growth habits, and foliage.
The Epidendroideae subfamily is the largest and most diverse orchid subfamily, containing over 20,000 species.
It includes the popular Cattleya, Phalaenopsis, and Paphiopedilum orchids.
This subfamily is characterized by its flowers, which have a three-lobed lip and a single-pointed column.
The Pleurothallidinae subfamily is the smaller, less diverse orchid subfamily, containing just over 1,000 species.
It includes the popular Masdevallia, Pleurothallis, and Restrepia orchids.
This subfamily is characterized by its flowers, which have a two-lobed lip and a multi-pointed column.
Within each subfamily, there are several genera and species, each with its own unique characteristics.
For example, within the Epidendroideae subfamily, the genera Cattleya, Phalaenopsis, and Paphiopedilum all have different flower structures, growth habits, and foliage.
Similarly, within the Pleurothallidinae subfamily, the genera Masdevallia, Pleurothallis, and Restrepia all have their own unique characteristics.
In summary, orchid taxonomy is a system of classification that is based on the physical and morphological characteristics of the plants.
It divides orchids into two subfamilies, Epidendroideae and Pleurothallidinae, and then further divides each subfamily into genera and species.
Each genus and species has its own unique characteristics, such as flower structure, growth habits, and foliage.
Monocotyledonous Group of Flowering Plants
Orchids are a diverse family of flowering plants that have been cultivated since ancient times for their beauty and unique characteristics.
They are classified into a specific taxonomic system, which places them in the monocotyledonous group of flowering plants.
This system is based on the physical and morphological characteristics of the plants, such as flower structure, growth habits, and foliage.
This classification system is used to group plants according to the number of seed leaves they have, known as cotyledons. Monocotyledonous plants, or monocots, are plants that have a single seed leaf, while dicotyledonous plants, or dicots, have two seed leaves. Monocots are further divided into two subgroups: monocotyledonous angiosperms and monocotyledonous gymnosperms. Orchids belong to the monocotyledonous angiosperm group, which are characterized by having flowers with petals and sepals that are most often in multiples of three, along with parallel-veined leaves.
Within the monocotyledonous group of flowering plants, orchids are further divided into two subfamilies: Epidendroideae and Pleurothallidinae. The Epidendroideae subfamily includes the most well-known orchid genera, such as Cattleya, Dendrobium, and Phalaenopsis. The Pleurothallidinae subfamily features smaller, more delicate orchids, such as Masdevallia and Pleurothallis. Each of these genera and species within them have their own unique characteristics, such as flower shape, size, color, and scent.
By understanding the taxonomic system of orchids, it is easier to identify and classify individual plants.
This can help in selecting and growing individual varieties, as well as in cultivating hybrids.
Understanding the taxonomic system can also help in understanding the evolutionary history of orchids, and how they have adapted to their environment over time.
Subfamilies of Orchids
Orchids are a diverse family of flowering plants that are popularly grown for their beauty and unique characteristics. They are classified into a specific taxonomic system, which places them in the monocotyledonous group of flowering plants. This system is based on the physical and morphological characteristics of the plants, such as flower structure, growth habits, and foliage. Orchids are further divided into two subfamilies: Epidendroideae and Pleurothallidinae.
The Epidendroideae subfamily includes the majority of the orchid species, and consists of over 30,000 species.
This subfamily includes the popular genera such as Cymbidium, Cattleya, Phalaenopsis, and Paphiopedilum, among others.
These orchids are known for their colorful and fragrant blooms, and some of them are even used for their medicinal properties.
The Pleurothallidinae subfamily includes over 3,700 species of orchids, and includes genera such as Masdevallia, Stelis, and Lepanthes.
These orchids are usually smaller in size and often have delicate, intricate flowers.
They are mostly found in South American rainforests and prefer humid, shady conditions.
In addition to these two subfamilies, there are also several other genera of orchids that are not classified into either of these two subfamilies.
Some of these genera are Bulbophyllum, Epidendrum, and Oncidium, which are popularly grown for their showy flowers and long-lasting blooms.
No matter which subfamily of orchid you choose to grow, you can be sure that you will be rewarded with a stunning display of beauty and unique characteristics.
With the correct care and attention, these plants can provide years of enjoyment and admiration.
Characteristics of Orchid Genera and Species
When it comes to orchids, no two are exactly alike.
Each genus and species of orchid has its own unique set of characteristics, which can be used to identify and classify them.
For example, some orchids have large, showy flowers, while others have small, delicate blooms.
Some orchids have fragrant flowers, while others have no scent at all.
The foliage of orchids also varies greatly, ranging from long, narrow leaves to broad, rounded ones.
Orchid genera can be further divided into species.
Species are plants with the same characteristics, and they are the smallest unit of classification in the orchid family.
Each species of orchid is typically identified by its flower shape, color, size, and scent.
Some species are grown for their beauty, while others are prized for their medicinal properties.
In addition to physical characteristics, orchids are also classified based on their growth habits.
Some orchids are terrestrial, meaning they grow in soil, while others are epiphytic and grow on other plants.
Some orchids are evergreen, while others are deciduous and lose their leaves in the winter.
