Asteraceae
is one of the largest
families of vascular
plants represented
by 30,000 species
and over 1100 genera
all over the world.
In India, there
are 900 species
under 167 genera.
Asteraceae dominates
other phanerogames
in Patalkot valley
too. I have reported
60 species belonging
to 44 genera of
this region. There
has been much contribution
made in publishing
records of family
Asteraceae by various
workers. So far,
there was no published
record of Asteraceae
from Patalkot valley
of Chhindwara district.
Therefore, extensive
surveys of Asteraceous
plants were carried
out during 1999-2000.
Specimens of the
survey were deposited
in Herbarium of
Botany Department
of Danielson College.
During the survey,
I explored the area
of Patalkot valley
that included- Gaildubbha,
Karayam Rathed,
Ghatlinga, Gudichhathri,
Karrapani, Tamia
Bharia Dhana, Bijauri,
Pandu Piparia, Sajkui,
Lahgadua, karrapani,
Sidhouli. Most of
the plants of family
Asteraceae occurring
in this region have
been identified.
The
medicinal values
of the plants are
based on the information
obtained from the
tribal viz., Bharias
and Gonds of Patalkot
valley.
Asteraceae
stands as the fourth
largest family in
India. The present
floristic study
survey showed that
Blumea is represented
by the maximum number
of species in the
area. Sieges beckia
is found only in
Tamia hills. Most
of the genera were
represented by only
one or two species.
Guizotia, Tagetes,
Helianthus, and
Spilanthes are being
cultivated by the
local farmers. Another
weeds like Parthenium,
Xanthium, Vicoa,
Cichorium, and Caesulia
were found to be
frequently.
Acanthospermum,
Ageratum, Parthenium,
Xanthium, Vicoa,
Cichorium and Caesulia
are the most common
weeds in the fields
of Patalkot Valley.
Few taxa such as
Parthenium hysterophorus,
Xanthium strumarium,
Tridax procumbens,
Ageratum conyzoides
and Acanthospermum
hispidum dominate
practically all
the areas and are
common weeds. Though,
some taxa are weeds
but rural and tribal
people utilize them
as medicines. Conservation
activities should
be concerned with
all medicinally
important species.
In Asteraceae many
species are weedy
but even some of
these are traditional
remedies and are
used as traditional
food. There is a
greater need to
combine ethnobotanical
information with
ecological studies
of Asteraceae.
