Interpretive Summary:

Technical Abstract: Tropical species are often expected to have short seedbank longevity and fairly predictable seedbank dynamics. This is not the case for tropical spiderwort (also known as Benghal dayflower, Commelina benghalensis L.). Although seedbanks near the surface appear to germinate rapidly – successively depleting the residual seedbank by 60 to 75% each year – populations buried at 20 cm demonstrate greater seedbank longevity. Differences in fatal germination and death between large and small aerial seeds (the only ones examined in the experiments) are apparent.
