Abstract

Chromatographic profiles of flavonoid extracts of P. purpureum and P. gattingeri are quite distinct, P. purpureum showing 12 species-specific compounds, and P. gattingeri showing 6 specific compounds.casei ond profiles i all putative hybrids except one exhibit compounds specific to each parental species.Three types of chromosomal abnormalities exist in putative hybrids which are not hM in either parental species, but completely normal meiosis is reported in several hybrids.
