Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin pediculus, meaning "little foot". [2] The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. [3] A pedicel may be associated with a bract or bracts. [4]
The fruit is a samara; the seeds are about 27 mm (1.1 in) long and 11 mm (0.43 in) broad, with a wing angle of 145° and a conspicuously veined pedicel. [3] [4] [5] The bloom period for Acer pensylvanicum is around late spring. [6] The spelling pensylvanicum is the one originally used by Carl Linnaeus. [citation needed]
Morphologically, an inflorescence is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis , as well as variations in the proportions, compressions, swellings, adnations , connations and reduction of main and ...
More importantly, the pedicel of T. cernuum is strongly recurved below the leaves while the other two species rarely exhibit this behavior. Northern forms of T. flexipes tend to have recurved pedicels and/or recurved petals. These forms closely resemble large plants of T. cernuum and so the two are often confused. In such cases, examine the ...
Flowers are solitary, bisexual, radial, with a long pedicel and usually floating or raised above the surface of the water, with girdling vascular bundles in receptacle. [ 11 ] [ 12 ] Some species are protogynous and primarily cross-pollinated, but because male and female stages overlap during the second day of flowering, and because it is self ...
Hopea pedicellata grows as a canopy tree, up to 40 metres (130 ft) tall, with a trunk diameter of up to 60 cm (24 in). It has buttresses and stilt roots. The bark is smooth.
The bracts, modified leaves at the base of a pedicel of a flower, a peduncle, or a branch, are longer than the pedicels on Pachypodium brevicaule Baker. They are narrowly oblong, having a somewhat elongated form with approximately parallel sides, to obovate, egg-shaped and flat with the narrow end attached to the stalk.
