Abstract

Oldenlandia lancifolia (calycose mille graines).

Abstract

Oldenlandia lancifolia is a herbaceous plant that behaves as an agricultural and environmental weed. It produces large amounts of tiny seeds that can be easily dispersed by water, animals and vehicles, or as a contaminant in soil and agricultural produce. It tolerates waterlogged conditions and can be found growing as an aquatic and semi-aquatic herb. Under suitable environmental conditions, it can form dense tangled mats that outcompete native plant species and can also alter the aquatic and riverine ecology of colonized areas.
