Flower Structure and Infloresence
Stamen
FLOWER PARTS: 2 Male parts consisting of an anther and filament.
Pistil
FLOWER PARTS: 4 Female parts of flower that may also be called "carpel" and consists of the stigma, style, ovary and the ovules
Ovule
FLOWER PARTS: A structure that develops within the ovary of a flower.
Corolla
FLOWER PARTS: ALL petals. Forms a whorl within the sepals and encloses the reproductive organs.
Calyx
FLOWER PARTS: ALL sepals. Layer of the perianth enclosing and supporting the developing bud
Filament
FLOWER PARTS: Holds up the anther
Style
FLOWER PARTS: Long, usually thin, stalk
Stigma
FLOWER PARTS: The "sticky" receptive tip of the pistil.
Sepal
FLOWER PARTS: each of the parts of the calyx of a flower, enclosing the petals and typically green and leaflike.
Petal
FLOWER PARTS: each of the segments of the corolla of a flower, which are modified leaves and are typically colored.
Anther
FLOWER PARTS: the part of a stamen that produces the pollen.
Ovary
FLOWER PARTS: the portion of the pistil in which the ovules develop.
Receptacle
FLOWER PARTS: the thickened part of a stem from which the flower organs grow.
Actinomorphic
FLOWER SHAPE: No matter how you cut them in half, both halves look the same.also refers to star-shaped flowers. Radially symmetrical. REGULAR
Zygomorphic flower
FLOWER SYMMETRY: Flower can only mirror in 1 direction; Bilaterally symmetrical. Irregular AKA Orchids.
Complete
FLOWER TYPE: 4 parts are all present; Corolla, Calyx, Stamens, and Pistils.
Imperfect
FLOWER TYPE: has 1 sex organ; Either Stamen (male) OR Pistil (female). May be staminate or pistillate flowers; Unisexual
Perfect
FLOWER TYPE: has 2 sex organs the Stamen (male) and Pistil (female) parts are present; AKA Bisexual or Hermaphroditic
Incomplete
FLOWER TYPE: has 3 or less parts;Missing either one or more of Corolla, Calyx, Stamens, or Pistils.
Ray floret
Head inflorescence; the OUTER ring of often brightly colored 'petals as in Sun Flowers (sun rays)
Pistillate flowers
Imperfect flower type with only FEMALE (pistil) parts.
Staminate flowers
Imperfect plant type with only MALE (stamen) parts
Solitary
Inflorescence Type. A pedicil terminates in a single flower. AKA Hibiscus, or spikes
Panicle
Inflorescence Type. Cluster of spikes, racemes, or corymbs. Panic because of all the pedicils
Catkin
Inflorescence Type. Elongated spike with unnisexual, apetalous flowers; Often pendulous (drooping)
Umbel
Inflorescence Type. Flat-topped or rounded with the pedicels orginating from a common point; May be simple or compound.
Corymb
Inflorescence Type. Flat-topped raceme with elongated pedicels reaching the same level; Outer pedicels are the longest.
Perticil
Inflorescence Type. Flowers whorled in rings at intervals up the stem.
HEAD (Capitulum)
Inflorescence Type. Many unstalked flowers massed together on a compount receptacle.
Raceme
Inflorescence Type. Series of individual flowers on unbranched stalk; with pedicle.
Spike
Inflorescence Type. Series of individual flowers on unbranched stalk; without pedicle (sessile)
Cyme
Inflorescence Type. more or less flat-topped cluster of flowers in which the central or terminal flower opens first and terminates the stem. Determinate
Spadix
Inflorescence Type: a densely arranged spike enclosed by a specialized leaf called a spathe
Monoecious
PLANT SEXUALITY: Both staminate and pistillate flowers on the same plant.
Hermaphrodite
PLANT SEXUALITY: Has both flower sex organs; only in perfect, or bisexual, flowers.
Dioecious
PLANT SEXUALITY: Staminate and pistillate flowers on seperate plants.
Perianth
Sepals + Petals; the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs (calyx and corolla).
Disk floret
The hundreds of tiny florets in the center of the disc. Each tiny disk floret is a flower in itself.
Pedicil
a small stalk bearing an individual flower in an inflorescence.
Inflorescence
the arrangement of flowers on a floral axis; a floral cluster
Peduncle
the stalk bearing a flower or fruit, or the main stalk of an inflorescence.
