What is Splash Seed Dispersal by Raindrops about?

Splash seed dispersal by raindrops was investigated for plants in southern Japan. Nine families, 10 genera and 19 species were confirmed as raindrop‐dispersed plants. The 10 genera were __Gentiana__, __Gratiola__, __Chrysosplenium__, __Mazus__, __Mitella__, __Ophiorrhiza__, __Sagina__, __Sedum__, __Trigonotis__ and __Veronica__. The method of splash rain dispersal in these species was clarified. Raindrop‐dispersed species were all small herbaceous plants with a vertical pedicel and an apically opening fresh capsule when the seeds mature. Open capsules were cup‐shaped or boat‐shaped and can accommodate raindrops easily. The raindrops splashed the seeds from the capsule. In general, the seeds weighed very little, but they were heavier than powder or dust seeds dispersed by wind. A strong negative correlation was found between seed weight and the number of seeds per capsule. In the case of __Trigonotis brevipes__ (Maxim.) Maxim., raindrops were received into the cup‐shaped calyx‐tube and dispersed the fruitlets. Some species, such as __Gentiana thunbergii__ (G. Don) Griseb., __Gentiana zollingeri__ Fawcett and __Ophiorrhiza japonica__ Blume, had hydroscopic movement capsules that open
