2. KNOWLEDGE BASED PREQUISITE for field work:
1. morphological structures and their terminology.
2. Systems of Classification.
3. Climate of the region.
4. Phygeography
5. Ecological niche
6. Phenology and flowering pattern
7. Help of local people/villagers

3. 1.SystemsofClassification.
e.g.
Subclass: Gamopetalae (corolla of united petals)
Series 1. Inferae (Inferior ovary)
Order 1. Rubials (epipetalous stamens)
Rubiaceae ( intrapetiolar stipules)
2. Asterales (epipetalous stamens)
Asteraceae (capitulum infloscence)
3. Campanales (Stamens not epipetalous)
Series 2. Heteromerae (Ovary superior, carpels more than two)
Order 1. Ericales (stamens alternate to petals)
2. Primulales (stamens opposite to petals, ovary 1-
locular
3. Ebenales
(stamens opposite to petals, ovary many locular)

4.  Series -Bicarpellatae (ovary bicarpellary)
3. Order: Gentianales (Corolla actinomorphic & leaves
Opposite)
(Oleaceae, Apocynaceae,Asclepiadaceae, Gentianaceae)
Order: Polemonials (Corolla actinomorphic & lvs alternate)
(Boraginaceae, Convolvulaceae, Solanaceae)
Order:Personales (Corolla zygomorphic ovules more than 4)
(Scrophulariceae, Bignoniaceae, Acanthaceae)
Order: Lamiales (Corolla zygomorphic, ovules 4)
(Verbenaceae, Lamiaceae)

5. Semi Evergreen forest

6. Drydeciduousforest

7. Ecologicalniche/Microclimate
Ceropegia huberi Ansari

8. Frerea indica

9. Impatiens aqualis
Fam.: Balsaminaceae

10. Utricularia triatula

11. Hubbardia heptaneuron Bor

12. Ceropegia maccannii

16. Locality specific plant species

17. Rediscovery

25. Ecological observations

26. Plants insect interaction

27. Owl moth

28. ‘Bee orchid’ Cotonia peduncularis
‘Bee Orchid’ is named because the lip of flower resembles with female Bee and Scientist
believes that the flower lip mimics a female bee seating on flower. It attract male bees thus
helping pollination.
