Reproduction in Organisms

Water hyacinth ($Eichhornia$) propagates vegetatively by offsets, not runners. An offset is a short, thick lateral branch with a tuft of leaves, found in aquatic plants like $Pistia$ and $Eichhornia$.
$Bryophyllum$ propagates by adventitious buds arising from the notches at the margins of its leaves (leaf buds) – correct.
$Agave$ propagates by bulbils, fleshy buds that fall off and grow into new plants – correct.
$Penicillium$ reproduces asexually by conidia – correct.
Hence the wrongly matched pair is water hyacinth – runner.
