Drosera cistiflora leaf

The glandular hairs or knob-shaped, glandular tentacles on top of this Drosera cistiflora leaf are shorter, denser and of similar length, while longer, more uneven in length and sparser below. Some of the leaf-tip glands on the lower side also appear bigger, not as red as those on top and all of them spherical. Some of the longer hairs below are whitish and shiny near the base, red near the tips.

Maybe landed prey is more likely to be captured on the upper surface, the many short hairs holding on, while the longer ones with bigger glands bend around, capturing the struggling, arrived bodies. 

Caught in the sticky droplets of mucilage from the glands, a gelatinous, gluey substance, the insect soon becomes digestible food itself. A much softer ending than being devoured by teeth and claws, maybe even narcotically drowsed for increased cooperation! Who knows?

The ascending, oblong to linear blade in picture is light yellow green and about straight apart from near both ends (Curtis-Scott, et al, 2020; Leistner (Ed.), 2000; iNaturalist; Wikipedia).
