My bicalcarata has been growing like crazy and the nectar glands have been very active. Here are some pics of the glands from the leaf, the pitchers have started secreting from the thorns and sides of the pitcher and the tendrils too since I now run a strip of flourescents under the lowland tank to keep the temps in the 90* range during the day.
Top side of leaf showing bumps covered in nectar droplets:
Bottom side of leaf showing "blackheads":
my N. rajah is different in that nothing secretes from the top of the leaf but all the "black pimples" on the underside secrete nectar.
