Caladenia melanema, commonly known as the ballerina orchid, [2] is a species of orchid endemic to the south-west of Western Australia. It is a rare orchid with a single erect, hairy leaf and one or two cream-coloured to pale yellow flowers with red markings and black tips on the sepals and petals .
Each flower is 14–20 mm (0.55–0.79 in) long, with two bracts at the base, and the six tepals are strongly recurved at their tips. [8] The tepals are violet–blue. [12] The three stamens in the outer whorl are fused to the perianth for more than 75% of their length, and bear cream-coloured pollen. [8] The flowers are strongly and sweetly ...
Flower forms are variable, with one head per stem; these can be as small as 5 cm (2 in) in diameter or up to 30 cm (1 ft) ("dinner plate"). The majority of species do not produce scented flowers. Like most plants that do not attract pollinating insects through scent, they are brightly colored, displaying most hues, with the exception of blue.
The corresponding male organ is called the antheridium. archegoniophore In liverworts of the order Marchantiales, a female gametophore: a specialized, stalked structure that bears the archegonia and the sporophytes. arctotoid In the Compositae, a style with a ring of sweeping hairs borne on the shaft of the style proximal to the style branches ...

Or, with bisexual and at least one of male and female flowers on the same plant. [2] Protandrous: (of dichogamous plants) having male parts of flowers developed before female parts, e.g. having flowers that function first as male and then change to female or producing pollen before the stigmas of the same plant are receptive. [6]
For example, male inflorescence in plants often produce more flowers than females . Furthermore, pollen export and ultimately paternity, often increases with flower number, even for plants with hermaphroditic flowers. Retention of older flowers with no pollinator rewards can lead to increased pollinator visitation rate and increased pollen removal.
Ipomoea indica [3] is a species of flowering plant in the family Convolvulaceae, known by several common names, including blue morning glory, oceanblue morning glory, koali awa, and blue dawn flower.
