Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in cymes, panicles or spikes. Number of genera: The family include 62 genera and comprises about 2,252 species. Characters of Ranunculaceae: A. Diagonostic Characters: Herbs, leaves exstipulate, incised blades, sheathing bases, flowers hypogynous , spiral or spirocyclic; sepals often decidous, usually petaloid; calyx and corolla free; stamens indefinite, free; carpels polycarpellary, apocarpous; fruit aggregate.
- 6. B. Vegetative Characters: Habit: The plants are annual or perennial herbs or a climbing shrubs (Clematis, Naravelia), rarely trees. They perennate by means of tuberous roots ( Aconitum) or rhizomes. Root: Tap root, adventitious or tuberous ( Ranunculus spp. And Aconitum). The tap root system is in the initial stage but sooner or later replaced by the adventitious roots. Stem: Herbaceous, in some climbing (Clematis) or underground rhizome or erect, branched. Leaves: Generally simple, alternate, or opposite (Clematis) exstipulate rarely stipulate (Thalictrum), sheathing leaf base, petiolate rarely sessile (Delphinium). In some aquatic species leaves may show dimorphy (Ranunculus aquatilis); unicostate or multicostate reticulate venation.
- 7. C. Floral Character Inflorescence: Solitary terminal (Anemone), axillary (Clematis), raceme (Aconitum, Delphinium) and cymose (Ranunculus spp.). Flower: Pedicellate, ebracteate rarely bracteate, hermaphrodite, (unisexual in Thalictrum). Mostly actinomorphic (Ranunculus) rarely zygomorphic (Delphinium and Aconitum) hypogynous, complete, pentamerous. Calyx: There is distinction of calyx and corolla in most of the flowers. Sepals 5, caducous, polysepalous, petaloid, imbricate or valvate aestivation. Corolla:
- 8. Petals 5, polypetalous, variously coloured, caducous or wanting; nectaries present at the base of petals. Petals are united to form spur (Delphinium).
- 9. Androecium: Stamens indefinite, polyandrous, spirally arranged on the thalamus, inferior; anther, extrose and adnate. Gynoecium: Polycarpellary (one carpel in Delphinium and 3 to 5 in Aconitum), apocarpous rarely syncarpous (Nigellla), ovary superior, marginal placentation (axile in Nigella). Fruit: Aggregate, etario of achenes (Ranunculus), etario of follicle (Aconitum), follicle (Delphinium), septicidal capsule (Nigella) or berry (Actaea), etario of drupes (Adonis), etario of berries (Hydrastic) and simple pod (Xanthorhiza). Seed: Small, oily and endospermic.
- 11. Pollination: Generally entomophilous (Delphinium, Aconitum, Aquilegia) and anemophilous in Thalictrum. Floral Formula:
- 12. Economic Importance Of Ranunculaceae: 1. Ornamental plants: Most plants are cultivated for their beautiful flowers like buttercup etc. 2.Medicinal plants: Some members are used as medicinal plants. Aconitum yields an alkaloid aconitina. Thallicirom yields mamira. It is used in the treatment of opthalmia. 3.Condiments: Some members are used as condiments. For example, seeds of nigella. It is also used as drug. 4.Weeds: Some members are need like R. Antriccaus.
- 13. 5. Importance of Honey: Most members of this family have nectaries. F lic nectaries have a great importance for honey bees. 6.Poisonous species: Some members of this family produce acrid juice. It is highly poisonous.
