Flowers, Inflorescences, and Fruits II

Slipper-shaped, as in the lady-slipper orchid

Strap-shaped, as in the corolla of the ligulate flowers of many members of the aster family

The flower of many members of the pea family, with a broad upper petal (the standard), two lateral petals (the wings), and two lower petals (the keel petals)

Bilabiate flower in which the upper lip is arched and the lower protrudes into the throat of the corolla, as in the toadflax

Sterile, often antherless stamens

The two anther sacs that comprise the anther

The stalk that holds up the anther

One end of the anther appearing terminal on the filament

Anther attached on its side to the filamet

Anther attached as in dorsifixed, but free-moving on the filament

Stamens united by their filaments into a single group

Stamens united by their filaments into two groups

Stamens united by their filaments into several groups

The structure formed by fused filaments

Syngenesious

An androecium of four stamens, with two of them on longer filaments, as in the mint and figwort families

An androecium of six stamens, four of them on filaments longer than the other two, as in the mustard family

Modifications of the anther apex, base or filament into horns, tips, tails, or other protuberances

With tail-like appendages

The stamens extending from the throat of the corolla

The stamens enclosed in the throat of the corolla

A pollen mass, as in the milk-weeds and orchids

A raised fleshy ring or cushion formed by the fusion of staminodes or nectaries on which the stamens sit

An enrolled, seed-bearing leaf

Gynoecium comprised of a single carpel, as in the pea family

Gynoecium composed of two or more carpels attached separately to the receptacle

Carpels are fused together in the gynoecium

How many carpels are typically fused together in a syncarpelous gynoecium?

The upper portion of the carpel, the area receptive to pollen

The midsection of the carpel, columnar or neck-shaped

The base of the carpel, the seed-bearing portion

The region lining the inner wall of the ovary, to which seeds or ovules are attached

Combination of the stigma, style, and ovary

Pistil made up of one unit

Pistil made of two or more fused units

The chamber within the ovary; there may be one or more

Immature seed

The region or line along which the ovules are attached

An interior wall which separates the locules in the event that two or more locules occur within an ovary

Position of the placenta

The placentae is located along the inner wall of the ovary

The placentae appears at the center of the ovary, either at the midpoint of a single septum or at the place where all the septa fuse together

There is no ovary, but rather, ovules are all attached to a central column

One ovule sits at the base of one locule

Series are superficially joined, but actually only touching

Series are organically fused

Series are partially fused in a somewhat irregular manner

Series are separate, not joined

The structure resulting from the stamens and gynoecium in the orchids being organically fused (or adnated)

Arising from the corolla, as in the stamens inserted within the corolla tube

The structure resulting from the adnation of the stamens and gynoecium in the milkweeds

The cup-like structure resulting from the fusion of the lower portions of the sepals, petals, and stamens; it is considered that each of these series is separately inserted on the rim of the structure, and mondelphy are not present

System of notation used to detail the structure of a flower

What letter is used to denote "calyx" in the floral forumla?

What letter is used to denote "corolla" in the floral forumla?

What letter is used to denote "androecium" in the floral forumla?

What letter is used to denote "gynoecium" in the floral forumla?

An arrangement of one or more flowers on a floral axis

Arising from the axil of a leaf

A reduced leaf, particularly one associated with a flower or subtending the inflorescence

A small second-order bract

Fused involucral bracts subtending a flower, as in an acorn cup

A set of sepaloid bracts

A secondary series of bracts, often subtending a subunit of an inflorescence

An organized set of bracts, either separate from one another or fused to form a cup

The supporting stalk of an individual flower in a multi-flowered inflorescence

The supporting stalk of a multi-flowered inflorescence or of a solitary flower

The central axis of an elongate inflorescence

Lacking a pedicel

Leafless flowering stalk

Having a scape

A comparatively large and sometimes brightly colored bract which partially to completely surrounds an inflorescence

Situated at the apex of a flowering stalk, as opposed to being axillary

A flower which terminates a flowering stalk or which arises from the axil of a leaf

Inflorescences no tcomposed of recognizable subunits which are themselves inflorescence types

On a solitary flower, the flower arising from the axil of a leaf along a stem

On a solitary flower, it is situated at the apex of a flowering stalk

An elongate inflorescence; the flowers sessile, dense or remote from one another

A small spike; the flowers inconspicuous and more or less hidden by bracts, as in grasses and sedges

A spike in which the axis is thick and fleshy; may be associated with an enveloping spathe, as in many members of the philodendron family (Araceae)

A pendant or erect inflorescence in which the typically unisexual and apetalous flowers are more or less hidden by scaly bracts; often fall as a single unit; usage traditionally restricted to such woody plants as oaks, willows, birches, and walnuts

A dense sphereical or rounded inflorescence of sessile flowers, as in the aster family (Compositae)

A one-sided coiled inflorescence resembling a fiddlehead, as in most members of the borage family (Boraginaceae)

An axillary whorl of flowers radiating in many directions, as in several members of the mint family (Labiatae)

An elongate inflorescence of pedicellate flowers on an unbranched rachis, the flowers dense or remote from one another

A flat-topped or somewhat rounded inflorescence in which all of the pedicels arise from a common point at the apex of the peduncle, as in the onion and its relatives

A flat-topped or somewhat rounded inflorescence in which the pedicels of varying lenghts are inserted along the rachis

A cluster of three flowers on a common peduncle, the central flower the oldest and flanked by the others

A much-branded inflorescence with a central rachis which bears branches which are themselves branced

A condensed, often cylindrical or egg-shaped panicle, as in the lilacs

A flat-topped or rounded inflorescence in which the peduncles (now called rays) of simple umbels (not called umbellets) are inserted at the apex of the peduncle, as in most members of the parsley family (Umbelliferae)

An elongate inflorescence in which umbels are inserted along a rachis, as in the English ivy

A corymb in which the branches terminate in heads rather than individual flowers, as in yarrow

A panicle in which the branchlets terminate in heads rather than individual flowers, as in many members of the same family (Compositae)

A panicle in which the branchlets terminate in spiletes rather than individual flowers, as in many of these cases

An infloresence in which spikletes are sessile along with unbranched rachis

A flat-topped or rounded inflorescence made up of primary, secondary or tertiary dichasia; the central flower is terminal and is the oldeset, as in many members of the stonecrop 

The blooming sequence of an inflorescence goes from the bottom to the top in a column and from outside to inside if the inflorescence is flat-topped
