Microsporogenesis in Hydrobryum griffithii (Wallich ex Griffith) Tulsane (Podostemaceae) from North East India

H. Lalruatsanga

Abstract: Flowers of Hydrobryum griffithii are cleistogamous, enclosed by a thin membranous spathe. The two anthers are borne on a forked filament placed adjoining to the stigmatic lobes. The two anther primordia initiated far before the development of gynoecium and enclosed by a distinct membranous perianth lobe. The anther primordium comprises a mass of undifferentiated meristematic cells covered with a unilayered dermatogen, thus conforming to tunica-corpus concept. A row of 3-4 cells in the hypodermis differentiated into an archesporium in each anther lobe.
