Angiosperms
monocots
commelinoid monocots
four orders of monocots
tepals
perianth members
alismatales
aquatic herbs and aquarium plants
sea grass
some plants submurged in seawater and some only halfway
liliales
petaloid monocots
large colorful flowers
aspearagales
large clade with many families
nectaries
have fused sides called
septa
open areas secrete nectar
septa nectaries
dioscoreales
only one family
produces yams
arecales
palm trees
3500 species
poales
grass family
such as grass farm crops
zingiberales
houseplants
maranta
calathea
canna lilies
gingers
banana
bird-of-paradise
classification of flowering plants
magnoliophyta
two distinct lines
monocots
one cotyledon on each embryo
leaves are elongated and strap shaped
eudicots
two cotyledons
reticulate venationg in the leaves
basal angiosperms
early angiosprores diverged into several clades
basal angiosperms
descendants of several groups from early angiosperms
became reproductively isolated
three extinct descendants
amborellaceae
small trees in forests
nymphaeaceae
water lillies
must submurged underwater
austrobaileyales
have not preserved all ancestral features
both basal angiosperms and monocots
uniaperturate
eudicots
basal eudicots
older classification of flowering plants
caryophyllales
old group is known as core caryophyllales
other flowering plants
anthocyanin pigments
form a nutritive tissue called perisperm
santalales
small order of parasitic plants
rosid clade
vegatative body
two large clades
malvids and fabids
together contatin more than 100 families
asterid clade
contain plants such as sunflower
they have iridoid compounds
only occur rarely outside this group
two small orders
lamiiids and campanulids
changing conepts about early angiosperms
wind-pollinated trees
became subclass Hamamelidae
wind-pollianted flowers
do not need to attract pollinators
ranalean flower
magnolia-type
relictual
generalized
it has all of the parts
