Angiosperms are characterized by the occurrence of double fertilization. However, Podostemaceae is considered an exception with the presence of only single fertilization (syngamy) though two male gametes are formed conventionally. To determine the ca

Floral morphology, phenology and mode of pollination have been studied in Indotristicha ramosissima (Wt.) van Royen. Although the plants are submerged, self-pollination (autogamy) occurs above water. This is aided by considerable elongation of the pe

The reproductive biology of Hydrobryopsis sessilis (Podostemaceae, subfamily Podostemoideae), a reduced, threatened, aquatic angiosperm endemic to the Western Ghats of India, was examined. This is the first report on the transition from the vegetativ

The Indian Podostemoideae are characterized by a dorsiventral thalloid plant body, the nature of which is controversial. Hydrobryopsis sessilis, selected for this investigation, is an endemic and highly reduced member. The mature embryo lacks a plumu

Reduced female gametophyte. Angiosperms are characterized by the phenomenon of double fertilization with Podostemaceae as an exception that appears to extend to the entire family. Our earlier work demonstrated the cause of failure of double fertiliza

Podostemaceae is a unique family of aquatic angiosperms. The vegetative body of the podostemads is represented by a thallus resembling that of an alga, lichen or a bryophyte, and lacking the conventional demarcation into stem, leaf and root. The podo
