A weblog put up by Emma

Sundews (Genus: Drosera)

The title ‘Drosera‘ comes from the Greek ‘drosos‘ that means ‘dew’ or ‘dewdrops’. They’re one of many largest genera of carnivorous vegetation on the planet.

Like all members of their household (Droseraceae), they lure, seize, and digest bugs utilizing a thick, gluey substance referred to as mucilage which they’ve on stalks masking their leaves. The bugs are used to complement the poor mineral vitamin of the soil through which the vegetation develop.

We got here throughout a big patch of Drosera stenopetala alongside a moist monitor close to the summit of the island.

Drosera stenopetala fruits within the hotter months between November and March, and recedes into dormancy over winter. They produce a solitary white flower that stands at about twice the peak of the leaves (see above). This was our first time photographing one in flower! They then produce tiny seeds which might be dispersed by the wind.
