Rosaceae generally have five sepals, five petals, and many spirally arranged stamens. The bases of the sepals, petals, and stamens are fused together to form a characteristic cup-like structure called a hypanthium. They can be arranged in spikes, or heads. Solitary flowers are rare.
The stamens arise between the petals and the disk. Hypanthium in Rosa Narcissus pseudonarcissus, showing from the upper bend to the tip of the flower: spathe, ovary, hypanthium, tepals, corona. In myrtles, the hypanthium can either surround the ovary loosely or tightly; in some cases, it can be fused to the walls of the ovary. It can vary in ...

The flowers have between 100 and 200 stamens measuring about 3.5 mm (0.14 in) long, and between 400 and 600 carpels. [ 4 ] : 683 [ 5 ] [ 6 ] [ 7 ] The fruit is an ovoid or somewhat cylindrical aggregate fruit measuring about 13 mm (0.51 in) diameter and up to 18 mm (0.71 in) long, and is bright red at maturity.
Flowers have 4 yellowish sepals, many yellow stamens, and may have 4 or no petals. [4] It is atypical of members of the rose family in that the flowers have no petals, have four rather than five sepals, and the leaves are opposite (occur in pairs on the twig), rather than alternate (occurring one at a time going up the twig.
It is from the Rosaceae family, meaning the G. vernum's simple rotate flower has five single petals, a sepal and stamens. [7] G. vernum grow in floodplains, along with Floerkea proserpinacoides, Glechoma hederacea, Laportea canadensis, Leersia virginica, Lilium canadense, Poa alsodes, and Viburnum acerifolium. [3]
Each flower, measuring about 8 centimetres (3 in) wide, has large petals and many stamens. [5] The fruit appears later in the summer as bright red rose hips. [6] Setigera's range overlaps with several other Rosa species, as well as some invasives. It can be differentiated from Rosa Multiflora by its tendency to have pink flowers.
It has clusters of small, creamy white flowers with five petals and numerous red-tipped stamens, which appear in late spring and persist into midsummer. The unique fruit is an inflated glossy red pod about 6 millimetres ( 1 ⁄ 4 in) long which turns dry and brown and then splits open to release seeds .
