Abstract
Floristic study is one of the important biological,
ecological and edaphic factors of an area. It is essential
for sustaining all animal life of an area and also for
maintaining heritable environment for that life. Adequate
knowledge of flora is necessary for planning sustainable
development of that area. The present study was focused
on flora of Venkatagiri Durgam forests located in
southern side of Nellore district.
A rock Fort about 13 kilometers west of Venkatagiri
Town. It was a defensive arrangement made by Rajah of
Venkatagiri, Venkatagiri Durgam is a peak 50 Km. west
of seshachalm hills. Venkatagiri Fort Built in 1775 A.D.
attracts visitors from all over the state. Front portion.
Fort namely Indira Mahal was built in 1883 A.O.
Venkatagiri is surrounded by a dense forest extending to
the Seshachalam hills. The forest houses many sensual
places of natural beauty like Kona. Malleswar Kona here
one can see water fall failing from 80 Ft. height.

1. Introduction
Andhra Pradesh is endowed with rich forest
resources having variety of flora and fauna the
Estimate of total number of medicinal plants of
Andhra Pradesh is around 1800 species as per the
data base maintained by FRLHT, Bangalore.
Traditionally, the local tribes depend on the
medicinal plants for treatment of common ailments
and the Knowledge is transmitted from generation
to generation through folklore. Due to ever
increasing biotic pressure, over exploitation and
regeneration of timber, pulpwood, fuel wood and
bamboo species, no special attention was paid to
identify, preserve and popularize the medicinal
plants. It is therefore, essential that a fillip be given
preserve the medicinal plants in the natural forest
Accordingly the state propose a number of forest
areas rich in flora and fauna including medicinal
plants as Medicinal Plants Conservation Areas
(MPCA).
Venkatagiri to mention a few are endowed with a
very rich flora and also abound in many medicinal
plants of importance varied micro-climatologically,
undulating topographical and ecological conditions
prevailing at various waterfalls (theerthams)
situated at different heights, provide a very
favorable habit and support the growth of the
medicinal plant species.
Tribals, a distinct ethnic group, usually confined to
definite geographical areas and speak common
dialect, are culturally homogenous and a unifying
social organization. They mostly live in the forest,
hills, plateaus and naturally isolated regions. The
area is inhabited by a large number of tribes like
Yanadis, Nakkalas, Irulas, Yerukulas, Dommara,
Vaddera, Sugalis or Lambadi’s and Chenchus. But
Yanadi community represented approximately 80%
of communities compared to others. Yanadis are
characterized by dark complexion, colour, short
stature, platyrrline nose, long head, prominent chin,
thick lips and scanty hair both on head and body
(Thurston, 1975.). Being in the non-coastal areas,
these tribes depend on Non-Timber Forest Products
mainly for their livelihood. The need for the
integration of local indigenous knowledge for a
sustainable management and conservation of
natural resources receives more and more
recognition (Posey, 1992). Moreover, an increased
emphasis is being placed on possible economic
benefits especially of the medicinal use of tropical
Ph ton

forest products instead of pure timber harvesting
(Pimbert and Pretty, 1995).
A very exhaustive account of hundred years of
Indian forestry was given by Rao (1961). An
illustrated account of flowering trees and shrubs in
India was published by Cowen (1965).
Flora of some parts of Andhra Pradesh is known
right from William Roxburgh (1795-1819).
Floristic data of Andhra Pradesh is available from
“Flora of the Presidency of Madras” by Gamble
(1916-1935). Flora of Nellore District is studied by
Suryanarayana, and Sreenivasa Rao (2002).
Floristic wealth of Nelapattu Bird Sanctuary,
Nellore district is recently studied by Basha et. al.,
(2012). Medicinal Flora of Penusila Narasimha
Sacred Grove is studied and reported 160 plant
species of medicinal importance by Basha et. al.,
(2012). This scenario motivates us to explain the
Flora of Venkatagiri Durgam Fort. After searching
the detailed review, it was found that no authentic
information is available on the flora of Venkatagiri
Durgam Forest. Keeping this in view, floristic
survey was conducted during March, 2012– June,
2013.
Hence, in the present paper an attempt has been
made to document the Phytoresources utilized by
tribes.
2. Study Area
Venkatagiri Durgam trail in still untouched other
than by the local and few adventure groups and is
not yet a regular destination for the trekkers. The
trekking pata is covered with small to medium
sized pebbles. Near Venkatagiri town the
Velugondas can be traced north ward through
Venkatagiri and Rapur rangers up to Somasila
where the river pennar enters Nellore district from
kadapa side through a deep gorge. Among the
Velugondas range of hills the Durgam in
Venkatagiri range and Penchalakona are the most
prominent once, with an elevation of over 1026
meters and 914 meters above mean sea level. The
Venkatagiri durgam used to serve as a fortress in
the historic part in the past we still find the
bunkers, guns in placements and store walls which
served as hydotes for infantry. Though the climes
along the bridle pathil exaction.
3. Materials and Methods
The field trips were undertaken during all the four
seasons of the year – Viz. summer, rainy, autumn
and winter. The Plant specimens were collected,
identified with the help of Flora of Presidency of
Madras (Gamble and Fischer, 1916-1920). During
the field work, the specimens collected for the
preparation of herbarium were processed in
accordance with the methodology adopted by Jain
and Rao (1977). For each species information has
been provided for valid scientific name, followed
by local name, family name and Habit.
4. Results and Discussion
Intensive studies of this unexplored area are
rendering interesting novelties of great botanical
and phytographical importance. Angiospermic flora
includes 185 species which fall under 107 genera
and 70 families with genus-species ratio is 1.3:1.
The presence of 185 species concludes that
Venkatagiri Durgam forests as one of the phyto
diversity rich spot of Nellore District. Dicotyledons
are represented by 170 species belonging to 170
genera of 43 families. Monocotyledons include 15
species belonging to 14 genera of 7 families. The
ratio of dicodtyledons to monocotyledons is 11:1
for species and 12.3:1 for genus.
Based on habit, flora comprises 143 species (50%)
under herbs, followed by 68 shrubs (24%), 54 trees
(19%) and 20 climbers (7%). 50% of flora
comprises herbs. Table .1 shows the number of
genera and species in respect of top ten dominant
families of Venkatagiri Durgam forest. Fabaceae is
the dominant family comprising 33 taxa of 18
Ph ton
366
genera followed aceae with 28 taxa of 14 genera.
Table.2 shows the list of top ten dominant genera
of the forest. Cassia is the dominant genus with 9

leafless twiner found frequently in the margins of
forests. Species of Striga and Santalum are partial
root parasites found commonly in grassy areas. But
invasive exotic species like Cassia occientalis,
Cleome viscose, Croton bonplandianum, Lantana

8) Medicinal plants:
Nearly 70% of flora having pharmacognostic value,
a few prominent medicinal plants are given here.

anthelmentica, Vitex negundo etc.
Endemism
The species restricted to a given region and occur
nowhere else are known as endemic species.
Pterocarpus and Decalepis are endemic to Eastern
Ghats. Out of six endemic genera of Nellore
district, three genera namely Caesulila
Roxb.,Decalepis Wight&Arn. And Sympagis
(Nees) are identified in Veligonda forests.
Atylosia cajanifolia Haines (Adavikandi) of
Fabaceae family is found in Hilly areas of East
Godavari, Srikakulam and Visakapatnam of
Andhra Pradesh by Sudhakar Reddy et.all. (2006).

Now it is also observed in the forests of
Venkatagiri Durgam of Nellore district. Most of the
endemic species are herbs (19), shrubs and trees are
of 9 each.
Research Highlights
A good number of plants seem to be endemic in
Venkatagiri Durgam of Eastern Ghat region. One
of the major tasks in the conservation process is to
prepare an inventory of RET plants to assess their
conservation. Similar documentation is not
available from Venkatagiri Durgam of Eastern
Ghat region. This paper attempts to fill this lacuna
by documentation of certain RET medicinal plant
species of Venkatagiri Durgam. The present work
highlights the Pterocarpus santalinus, it is an
intresting species in this area and has edaphic
preference at higher elevations Shorea tumbuggaia
is rare but identified in this area only, found
associated with Red sanders at high elevation.
Croton scabiasis is another associate of Red
sanders in Venkatagiri Durgam, Seshachalam hills,
Eastern Ghats, Nellore district of Andhra Pradesh.
Limitations of the Research
Present research is mainly concentrating on the
identification and documentation of RET plants
species of the study area. Population studies
including species richness, species diversity,
conservation priority index have to be calculated.
Distribution analysis of Ret plant species in
different parts of study area also planned but not
able to studied due to the shortage of time and so
many other factors.
Research Potential
There is lot of research potential regarding to RET
plants. Genetic mapping of RET plants has to be
done for comparative analysis, molecular markers
have to be prepared which are useful in the
identification of RET plants of different regions of
Eastern Ghats, It also allows the opportunity for the
establishment of tissue, embryo and somatic cell
banks of RET species. Studies of Seed Biology
helps to propose holistic and multidisciplinary
efforts for the conservation of RET plants species.
Justification of the Research
Conservation of phytodiversity and medicinal
plants in its bicultural perspective not only implies
conservation of biodiversity but also places an
equal emphasis on conservation of cultural
diversity. It is especially desirable in case of
species where wild populations have dwindled to
critical levels. Database will be useful to
researchers, foresters, policy makers, all those who
are involved in conservation programmes. It
provides the scope for the study of reproduction
biology of the RET plants which is helpful in their
cultivation and conservation programmes.
Recommendations
Representatives of all groups of plants contribute to
the health of global ecosystem and to human
welfare. As such, any loss of phytodivenity has the
potential to negatively impact the future of the
human population. Among the top priorities for
effort in plant diversity research are training of
amateur and professional experts in the taxonomy.
Taxonomy especially in the identification of
medicinal plants is very much essential. There is an
urgent need to conserve in situ all forms of life
along with its support system. The main threat to
the ecosystem in the area is felling and smuggling
of red sanders which is endemic to the area and due
to its international market. It is noted that about
10% of all plant species are endangered indicating
wide spread degradation of ecosystem and
therefore the urgent need for strategic conservation
action.
Acknowledgment
The authors are thankful to the tribal people of
Venkatagiri Durgam for their help in the
transmission of traditional knowledge.
Conclusion
Venkatagiri Durgam is one of the richest gene
banks of Phytoresources in Andhra Pradesh. Tribes
of Venkatagiri have very good knowledge on the
usage of phytoresources for various purposes
including medicines for various ailments.
According to state government of Andhra Pradesh
propose number of forest areas rich in flora and
fauna including medicinal plants as medicinal plant
conservation areas (MPCA) one such MPCA has
been Established at Venkatagiri. But this traditional
knowledge is restricted to older people only
because of the effect of modernization among
youngsters. Therefore it is necessary to record and
protect that traditional knowledge for future
generations.
