Abstract
The angiosperm family Orchidaceae comprises ~900 genera and 30,000–35,000 species, which are distributed all over the world. Besides, more than two lakhs man made hybrids are available. The unparalleled unique characteristic features and adaptations to thrive on almost all habitats on the earth made this group of plants as a distinct one from the rest of the plants in the Plant Kingdom. The diversity in morphology, physiology, and genetic peculiarities induces large level of speciation with remarkable evolutionary significance. The constructions of orchid flowers are always a curiosity to both layman and scientists. The unique flower characters (phenotype) such as wide variations in floral morphology, colors, shapes, enchanting smells to attract pollinators are the expression of genes (genotype). The construction of orchid flowers as well as the efficiency in successfully carrying out the function for which they are intended and underlying genetics is briefly discussed.
