In this article, we will discuss various Hypogynous flower examples, each with a brief description and corresponding images.
Non-fruit flowers and flowers with fleshy fruits are the two types of hypogynous flowers. So, to understand more about this, let’s have a look at several hypogynous flower examples that include the family Malvaceae & Annonaceae, each with a brief description below.
The attachment of different floral whorls to the gynoecium on the thalamus is how the sepals, petals, and stamens are attached to the gynoecium. The thalamus or receptacle is the flower’s inflated structure or compact stem that carries the floral whorls. The ovary is the female reproductive part of the flower, and the stamen is the male reproductive part of the plant in this floral whorls attachment. The ovary of the flower or the gynoecium occupies the terminal whorl.
The flower containing sepals (the calyx), petals(the corolla), and stamens placed below the ovary and above the thalamus of the plant is known as hypogynous. So, in hypogynous, hypo means ‘below or lower,’ while gynous means ‘gynoecium’ of the flower.
In other words, everything (all floral whorls) is below the gynoecium (ovary), and thus, the ovary is superior in this case. Hypogynous flowers can easily detach such kinds of ovaries from the thalamus.
Non-fruit flowers and flowers with fleshy fruits are the two types of hypogynous flowers. So, to understand more about this, let’s have a look at several hypogynous flower examples that include the family Malvaceae & Annonaceae, each with a brief description below.
Hypogynous Flower Example
1. Tulip
Tulips, also known as Tulipa, are a genus of herbaceous perennial bulbiferous geophytes that bloom in the spring. Since the calyx, corolla, and stamens are linked to the receptacle below the ovary, tulips are hypogynous flowers.
2. Tomato Flower
The tomato blossom is a hypogynous flower that exhibits all of the characteristics of a superior ovary. Tomato plants produce yellow blossoms that flowers must fertilize before fruit can form.
3. Snapdragon
Antirrhinum majus, often known as a dragon or dog flower, is another name for Snapdragon. It exhibits axile placentation, as evidenced by a cross-section over its ovary.
4. True Berries
A true berry, such as blueberry, cranberry, or grape, is a simple squishy fruit composed mainly of seeds in a single flower’s ovaries. The hypogynous flower of these true berries has everything below the gynoecium.
5. Persimmon
The edible fruit persimmon is a berry. It belongs to the Diospyros genus, which includes a variety of tree species. Male and female flowers are developed on different trees in the persimmon. On the other hand, Persimmons have a hypogynous flower in which the ovary is superior and a perfect flower kind of plant.
6. Mustard Flower
Brassica rapa, or mustard flower, is a bright yellow bloom. It is a member of the Brassicaceae family. It is a hypogynous flower with all of its characteristics.
7. Brinjal Flower
When a brinjal flower is pressured, the blossoms dry up and fall off, leaving no fruit. This type is thought to be superior since its flower is hypogynous and has all ovaries.
8. China Rose
Hibiscus rosa-Sinensis, often known as China Rose, is a hypogynous flower with coiled aestivation. As an ornamental plant, this species is widely grown.
9. Lupin flower
Lupinus and lupine are common names for the same flower Lupin. It is a flowering plant genus belonging to the Fabaceae family of legumes. The plants are generally herbaceous perennials, but there are occasional annuals and hypogynous flowers with everything below the ovary.
10. Sunn Hemp
Crotalaria juncea, popularly known as Sunn Hemp, is an annual herbaceous legume that grows in an upright shrubby form. The terminal blooms of Sunn Hemp are a bright yellow color, and the light brown pods are tiny and swollen. The perianth and stamens are linked to the thalamus below the gynoecium, making it a hypogynous plant.
11. Bengal Gram
Bengal gram flowering is a hypogynous flower. The ovaries of these flowers are easily detachable from the perianth.
12. Chilli flower
Chilies are members of the Solanaceae family. The chili flower is a bloom that grows on the chili plant. Chilli flowers are small, white, and dangle from the stem like a pendant. Chili blossoms are pollinated, resulting in the development of chillis. It has a hypogynous pattern and positioning.
13. Bean
Beans are members of the Fabaceae or Leguminosae family. It is the 3rd largest flowering plant family, with tens of thousands of species. The bean is a blooming plant that produces ripe seed pods and blooms.
14. Petunia
Petunia is a species in the Solanaceae family. Most of the species seen in gardens are sensitive perennials with blooming plants. Petunias are generally insect-pollinated and hypogynous based on various floral whorls attachment to the perianth
15. Withania
Winter cherry, or Withania Somnifera, is a member of the Solanaceae family. It’s an annual evergreen shrub with delicate, green, bell-shaped hypogynous flowers.
16. Aloe flower
Aloe belongs to the Asphodelaceae family. Aloe flowering is an uncommon flower that blooms. Aloe blooms are cylindrical and grow densely grouped and suspended at the tip of simple or branched, has leafless stalks. They are frequently yellow, pink, orange, or red.
17. Potato
Potato plants generate blossoms after their growing season, making them more than just a crop. Flowering indicates that the vines have reached maturity and have sufficient leaf area to begin generating tubers.
These potato flowers are hypogynous, and flowering on potato plants is common, but the flowers normally dry up and fall off instead of forming fruit.
18. Onion
The onion belongs to the genus Allium, part of the Amaryllidaceae family. The stalk flowers of the onion plant are hypogynous, with the superior ovary on top—the onion blooms in the spring; however, some bloom in the fall.
19. Mallow
Malva or Mallow is a Malvaceae genus of herbaceous plants. Malva sylvestris flowers bloom in axillary bunches. Malva’s flowers are hypogynous and prolonged along with the stalks, with the blooms towards the bottom emerging earliest.
20. Durian
The Malvaceae family includes durian. Durian flowers vary from small to medium in size, and they bloom in clusters. It’s not just the world’s stinkiest but also the most expensive fruit. Its every hypogynous flower is comprised of five spherical petals, a sepal, a pistil, and thin bundles of elongated stamens.
21. Cacao Flower
The cacao/cocoa tree, also knowns as Theobroma cacao, belongs to the Malvaceae family. It also has clusters of flowers that release a shower of inflorescences from growth terminals around the trunk and hang to a stem. The cacao flower has a hypogynous design.
22. Sugar Apple
The scientific name for sugar apple is Annona squamosa L. It has a flower that bears fruits named sugar apple or custard apple. It has a greenish-yellow flower that blooms singly as well as in clusters. The placement of these floral whorls on the thalamus is hypogynous type.
23. Hollyhocks
The order Mallows includes the hollyhocks flower. It blooms in the middle of the summer, with many flowers on long spikes. Its floral whorls are arranged in a hypogynous pattern making it a hypogynous flower.
24. Mitrephora
Mitrephora is a genus in the Annonaceae family. Mitrephora flowers feature many rectangular to wedge-shaped stamen with dual-lobed anthers arranged dorsally. Its flowers have oblong ovaries and naked carpels. The ovules are arranged in two rows longitudinally within the ovaries, making it a hypogynous flower.
25. Ylang-Ylang
Cananga odorata, also known as ylang-ylang, is a member of the Annonaceae family. The flower is stalked, elongated, and hanging, with six slender greenish-yellow and sometimes pink petals. Everything is attached below the gynoecium, a feature of hypogynous flowers.
26. Cyathocalyx
Cyathocalyx is a constituent of the Annonaceae family. It has greenish petals and blooms in clusters. All hypogynous characters are displayed in this type of flower.
27. Sapranthus
Sapranthus is a blooming plant communities genus in the Annonaceae family. The blooms are dark purple, big, fleshy, and noticeably grouped when fully developed. Their floral whorls are positioned as hypogynous flowers.
28. Brassica (Cabbage)
Brassica flowers are more durable, less delicate, and long-lasting. The flower’s petals are feathery, curled, and scrunched up. The term flower originating below the point of ovary insertion is often used to describe a flower with sepals, petals, and stamens implanted below the gynoecium showing it as a hypogynous flower member.
