FLOWER PARTS OCCUR IN WHORLS IN THE FOLLOWING ORDER- SEPALS, PETALS, STAMENS, PISTILS.

PEDICEL - flower stem
RECEPTACLE - base of flower where other parts attach
SEPALS - small and green, collectively called the CALYX
PETALS - often large and showy, collectively called the COROLLA
PERIANTH - CALYX + COROLLA
STAMEN - composed of filament and anther

ANTHER - structure containing pollen grains
FILAMENT - structure connecting anther to receptacle

ANDROECIUM - collective term for stamens
CARPEL - structure enclosing ovules

PLACENTA - place of attachment of ovule(s) within ovary
STIGMA - receptive surface for pollen
STYLE - structure connecting ovary and stigma
OVARY - basal postion of pistil where ovules are located

The ovary develops into the fruit and contains ovules (eggs) which develop into seeds after fertilization.

LOCULE/CELL - chamber containg ovules
PISTIL - Collective term for carpel(s)
THE TERMS CARPEL AND PISTIL ARE EQUIVALENT WHEN THERE IS NO FUSION, IF FUSION OCCURS THEN YOU HAVE 2 OR MORE CARPELS UNITED INTO ONE PISTIL.
GYNOECIUM - collective term for pistils, a gynoecium can be composed of:

1. A single carpel = simple pistil
2. Two or more fused carpels = compound pistil
3. Two or more unfused carpels = two or more simple pistils

To determine the number of carpels in a compound pistil, count the locules, points of placentation, styles, stigma lobes, and ovary lobes.
COMPLETE FLOWER - A flower having all four whorls
PERFECT FLOWER - A flower having both sexes
UNISEXUAL FLOWER - A flower having one sex

bumping back onto the 'recent posts' area - there is some good stuff here

Holy Moley, allabout!!! VERY impressive! Here's another definition:
crop failure--when I try to grow something that takes too much care, needs too much watering, begs for too much "babysitting" and probably shouldn't be grown in my zone, ANYWAY!

Ya know...I think the ARTICLES section link in the green bar is empty.

Shall we fill it with some articles such as this dictionary?

 

[Nifty]

Ooohh... thanks for noticing Marshall!

Actually I need to temp remove that until we decide:
1) Which system for articles we're going to use
2) If / how we're going to convert the old articles over (which are still live, just not linked to from here).

 

[897tgigvib]

Nifty, would it be alright if some of us members work together to create articles also? Perhaps in a format you approve?

This gardening dictionary would be a great one to start with.

Marshall, you're my new best friend!

Not only would it be ok, but I'm working on ways to really encourage our members to have fun with creating articles.

I think you're on to a great idea with taking existing threads and consolidating the wealth of info into individual articles!

Keep the great ideas coming!
