The development of the transmitting tract in the pistil of Hacquetia epipactis (Apiaceae)

Hacquetia epipactis has a wet, nonpapillate stigma. Stigmatic cells are moribund at maturity and become disrupted because of accumulated and ascending stylar secretion. The stigmatic surface coating is produced completely by the stylar transmitting tissue. The style is a half-solid type, with large...

Description
Summary:Hacquetia epipactis has a wet, nonpapillate stigma. Stigmatic cells are moribund at maturity and become disrupted because of accumulated and ascending stylar secretion. The stigmatic surface coating is produced completely by the stylar transmitting tissue. The style is a half-solid type, with large secretion-filled schizogenous channels. The secretion mainly contains polysaccharides mixed with a small amount of lipids. Pollen grains germinate within the stigmatic secretion and the pollen tubes grow directly into the stylar channels.
