Definition of Botany
![Page 6: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/6.jpg)
Indian Botanical Classification
Western Botanists divide trees into two classes viz.;
1) Endogenous or growing from inside and
2) Exogenous or growing from outside.
Ancient Indian Botanists divide trees into four classes viz.;
1. Nissar – Trees having no hard core
2. Antassar- Trees having hard core inside
3. Bahhissar – Trees having hard core outside
4. Sarvassar- Trees having core throughout their cross-section
![Page 7: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/7.jpg)
1.Nissar trees are Pipal, Banyan and Holy fig.
However thick these trees grow they form no core.
Their flowers are closed. Fruits are bunch of flowers

2.Bahhissar trees, Endogenous trees, as per
western Botanist, are Bamboo, Coconut or
Bettle nut and others of this class.

3. Antassar trees or Exogenous trees, as per
western Botanist, are Mango, Jackfruit, Neem
tree and other trees.

4. Sarvassar trees are hard throughout the
cross-section. Tamarind, Babul, Shirish tree
and marking tree are the examples of this
class.

Forbidden Trees
• Milky Trees: (with poisonous juices): milk bush
• Thorny Trees: Babul or Prickly pear
• Trees having hard through out: Tamarind or
Bunyan tree.
• Bushes: Which give shelter to small animals and
consequently serpents frequent them.
• Fruit bearing Trees: Mango, Guava etc. People are
tempted to throw stones.
• Other Trees (Trees without hard core)

Tree Recommended near Habitat
High trees or fruit bearing trees may be
allowed, provided they cast no shadow at
noon or overtop the building. The distance of
tree from house should be twice the height
of tree.

Trees permitted to grow near Habitat

Confinement of trees (Vratabandha)
Some holy trees may be allowed to grow near buildings, but they should be confined to a certain area within a circular wall. Trees transgressing this boundary by breaking through it, should be pruned to avoid damage to the building.
![Page 20: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/20.jpg)
Classification of Trees
According to Gender
Gender: This subdivisions is based on the
direction of growth of the tree.
• Male trees : Trees strong vertically or in compression
• Female trees: Trees strong laterally or in tension
![Page 21: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/21.jpg)

Hard wood Trees
![Page 23: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/23.jpg)
According to Age
Classification of Trees
Age: This subdivisions is based on the five life spans
the tree: Child, Young, Adult, Aged and Dead
The trees in the middle three spans of life are to be used
for constructional purposes. The trees in the extreme two
spans (childhood and decay) of life should not be used.

Directional suitability of Trees
![Page 25: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/25.jpg)
Selection of a Tree for Timber
• in the compound of religious place,
• struck by lightening ,
• scorched by fire,
• grown in covered area, in unhygienic conditions or
• grown along the roadside,
• broken by wind or animals or vehicles impact,
• entangled by other trees or wound by creepers,
• grown in anthills or supporting honey beehive,
• grown on cremation ground or which harbors vultures or
owls.
Do not Select a Tree, which is
![Page 26: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/26.jpg)
To ascertain the stage of life of a tree, a bore through the stem, at two feet above ground is made. The age of the tree is indicated by 1) color of the core,2) hardness and 3) juice oozing from the bore.
If a tree is already cut, instead of juice, the sound produced by tamping with a heavy rod, will indicate the stage of age.
Formation test

Selection of Wood
![Page 28: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/28.jpg)
Knots in Wood
The wood should not be full of or devoid of knots.
![Page 29: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/29.jpg)
For seasoning of wood, it should be placed on sand
with bottom portion facing wind blowing from west or
south direction.
Seasoning of wood

Before felling the tree, the branches of tree should be cut first to avoid unusual strains.
Felling the tree

Preservation of Wood
The wood should be painted to avoid the
losses of oily substance. An oil coat should
be applied every year after rainy season.
![Page 32: Botany of Ancient India](https://reader030.vdocument.in/reader030/viewer/2022012308/543eaa15afaf9f255e8b4997/html5/thumbnails/32.jpg)
Frames and door shutters
Wood for frames and door shutters should be of same
type so that the action of weather may be same on
both. Unequal action produces unequal strains and it
is detrimental to architecture.

Tree Extracts
For seats of balloons extracts of few trees
are specified in Agastsamhita.

The juice of coreless trees contains water retarding
substances (lac) and hence the juice was used in
preparing silk cloth gas holders in ancient India.

Conclusions
• The study of botany was very useful and essential
for Indian engineers.
• It had formed a part of ancient Indian Engineering
sciences.
