Morphology Of Flowering Plants 2 Flashcards
Position of floral part on thalamus
HYPOGYNOUS: Gynoecium is highest
Ovaries are superior
MUSTARD, CHINA ROSE,Brinjal,Petunia
PERIGYNOUS: Centre, other at rim or periphery to thalamus
Ovaries are Half inferior
PLUM, RISE, PEACH
EPIGYNOUS: Ovaries are enclosed complete, fused, other part are above
GUAVA, CUCUMBER, BITTERGOURD, Sunflower ray floret
Calyx
Corolla
Androecium
Gynoecium
Sepal
Petal
Stamen
Csrpel
Types of calyx
Gamosepalous sepal United
Polysepalous- sepal free
Corolla shape
Tubular, bell shape, funnel shape, wheel shape
Aestivation
Arrangements of sepal, Petal in floral bud with respect to other member of the same whrol Valvate Twisted Imbricate Vexillary
Valvate
Margin just touch eachother, no overlapping
CALOTROPIS
Twisted
Sepal, peal overlap adjacent sepal, Petal
CHINA ROSE, LADIES FINGER, COTTON
Imbricate
Margin overlap but in different directions
CASSIA, GULMOHUR
Vexillary
Large (standard) overlap smaller lateral (wings) overlap analyst anterior (keel)
Androecium
Male
Inner to corolla
Stamen- anther, filament
Length of filament may varry like in Salvia, mustard
Sterile stamen
Staminode
Adhesion of stamen
Stamen attached with Petal: epipetalous, BRINGAL
With preinath: epiphyllous: LILY
Adhesion of stamen
Free stamen- polyandrous
1 bundle: monoadelophous, China Rose
2 bundle: diadepholus, pea
More: polyandrous, Citrus
Gynoecium
Female
Free calpel, lotus, rose- Apocarpous
Fused carpel- mustard, tomato- synchronous
Ovary
Basal, swollen Chamber of ovaries- Loculi 1 C- unilocular 2- bi 3-tri Ovules are borne in these chambers
