Family Asteraceae (Asim Farooq)

More than 23,000 species across 1620 genera and 10 subfamilies and round
about 17 tribes.
 Originated in period of Crataceous before separation of America and Antarctica .
 Numerous distribution in tropical, and subtropical regions.
 Form a monophyletic group and are easily recognizable.
 Mostly herbaceous but some shrubs , trees and climbers do exist.
 Branched taproot system, herbaceous or woody branched stems, leaves are simple,
alternate or opposite, exstipulate, petiolate, hairy, reticulate venation, racemose
inflorescence, unisexual, actinomorphic, heterochlamydeous, epigynous flower, sepals
sometimes absent or scaly persistent, polypetalous, 5 stamens and 2 carpels, basal
placentation, nut shaped fruit known as cypsela, in mature seeds the endosperm is
scarce or non-existent .
 Adapted several methods of reproduction.
 Store energy in the form of inulin, synthesize other compounds like alkaloids,
acetylenes and terpenoids etc.
Family of much economic importance as:
Food plants like Lactuca sativa, Helianthus tuberosus.
Oil seeds like Helianthus annuus, Carthamus tinctorius, Osteospermum sp.
Medicine like Chamaemelum nobile, Inula helenium, Santolina chamaecyparissus.
Ornamentals like Dahlia imperialis and Chrysanthemum sp., Tanacetum vulgare.
Economic loses due to Ambrosia artemisiifolia.
