the rosette.
Flowers are small at up to 5mm, white and 5-petalled.

There are 3 divided, linear, white styles and 6 short,
white stigmas.
The 5 sepals are pale green, toothed and a similar size
as the petals.
Fruits are capsules.

purple, and covered in glandular hairs.
The hairs trap and kill insects and the leaves absorb
nutrients from their carcasses.

and pink stigmas compared to the white stigmas and
