A flower with a solitary stamen is monandrous. The terms dicmdrous, triandrous, tetrandrous, p9n,tcmdrous, etc., and pol/yrm- drous, signify furnished with 2, 3, 4, 5, many stamens. Compare § 67. When the stamens are very numerous, they are arranged in several rows. Stamens take their origin from floral leaves in the same way as pistils. The filament represents the petiole, and the anther the blade of a leaf. The blade curved in, until each of its edges unites with the midrib, forms a 2-celled anther. The usually well-marked stripe, which exi ends be- tween the anther-cells, answering to the midrib of the leaf, is the conneclme or conneotile. The anther is the essential part of the stamen (see § 33), and commonly it is 2-lobed and 2-ceUed—rarely i- or 1-celled. It is the function of the anther to produce pollen, and discharge it at maturity. "With regard to their position, the stamens are hy- pogynous, when they spring from the receptacle below the ovary or ovaries (Cut X., Fig. 1); perigynous, when they are inserted on the calyx around the ovary (Fig. 2); epipe- talous, when they are fixed on the corolla; epigynous, when they stand on a level, answering to the summit of the ovary so as apparently to spring from the top of this or-.
