14 A flower is regular when all parts of each whorl of organs are of like size and shape and irregular when some parts of one or more whorls of organs differ from other parts of the same whorl either in shape, size or both. A corolla with all petals being the same in shape or size is called regular corolla and if the petals are of different shape or size, an irregular corolla. One must therefore check if what is being referred to is a regular flower or a regular corolla, an irregular flower or an irregular corolla. Remember a flower may be irregular even if it has a regular corolla. Some authors consider a flower irregular if any of its whorls is irregular but other authors consider a flower irregular only if the calyx and/or corolla is irregular. One should find out the particular usage employed in a book or manual. Flowers are symmetrical when the parts of all whorls of organs are the same in number or in multiples of the prevailing number and unsymmetrical when there is a variation from the standard number in one or more whorls of organs. Flowers are called 3-merous or trimerous, when the parts are in threes, 5-merous or pentamerous when the parts are in fives, etc. According to the number of stamens, plants with 1,2,3, or many stamens, are called monandrous, diandrous, trianrous or polyandrous respectively. Those with two long and two short stamens in the flower are called didynamous and those with four long and two short stamens are called tetradynamous. Plants with 1,2,3, or many petals in the flower are referred to as monopetalous, dipetalous, tripetalous or polypetalous respectively. As to the union of parts, the term connate refers to the union of the parts of the same whorl or organs and adnate refers to the union of the parts of one whorl of organs to the parts of another whorl of organs. When the sepals are more or less united, the calyx is said to be gamosepalous or synsepalous and when they are quite free from each other, as polysepalous or choricepalous. Corresponding terms expressing the union or non-union of the organs of the corolla are gamopetalous or sympetalous and polypetalous or choripetalous respectively. The gamopetalous corolla usually has three parts, the tube which is the contracted part below, the limb which is the spreading part above, and the throat which is the junction between the tube and the limb. In flowers with regular gamopetalous corollas, the shape of the corolla may be tubular, that is, elongated and shaped like a tube or cylinder; funnel-shaped, gradually spreading from near the base to the apex; campanulate, with a broad and rather short tube widening upward like a bell; salver- shaped, the tube is cylindric and the limb spreads more or less perpendicular to the tube, the limb or its lobes being shorter than the tube; rotate or stellate, the limb or its lobes are longer than the tube and spread radiately from the much shorter tube, the flower looking like a wheel or star; and Mceolate, the tube is ovoid or globose, contracted above into a short neck and again expanded in a TOw limb like an urn.
