Specie
Petals, Sepals, or Tepals
• The
alstroemeria is
a type of
flower that has
tepals, because
the petals and
sepals are
similar.
Stamen: Filament, Anther
Pistil: Stigma Ovary
Pistil Types

Staminate: Has only functional stamen
Carnation = male
Pistiliate: has only functional pistil
Perfect: Has both functional stamen
and pistil

Tepals : Petals and Sepals
Both the striped petals and the sepals,
which are the leaves between the petals,
come in an arrangement of three each.
The petals and sepals have similar color
and texture, so the sepals actually
resemble the petals much more closely
than they resemble most green leaves.
Reproductive Structures
Alstreomeria plants contain six
undivided stamens, which are the
male reproductive stalks extending
from the center of the flower. The
ovaries of the flower have three
carpels and are known as inferior,
because they are fused to the base
floral structure.
Leaves
Alstroemeria plants are like grasses,
irises and lilies in that veins go up to
the leaves but do not branch across.
These leaves are actually upside down
because they twist as they extend
from the stem. This feature is known
as being resupinate.
