The enigmatic monospecific Bishopanthus of the tribe Liabeae (Compostiae/Asteraceae) has never been fully understood. It has not been possible to examine it in detail since it was described, because most of the type material was destroyed shortly after it arrived at the US National Herbarium, the morphology is insufficient to assign it to a subtribe, and the small amount of leaf material that r...

Embryological studies indicate Eupatorium laevigatum to have Antennaria type diplospory with precocious embryony. The embryo sac is of the Polygonum type and the polar nuclei fuse before anthesis (maturation of the stamens). Endosperm development is autonomous and the central cell divides only after the initial stages of embryo formation. It is estimated that about 10% of the florets in anthesi...
