@cpnut: glad you enjoy them
@alienfx: Medan is the capital of Sumatra Island, as for Medan city herself surely no neps, but for the Sumatra Island we have lots of them, the closest to the habitat of neps from Medan is about two hours drive up to mountain and we have spectabilis, rigidifolia, pectinata, tobaica, etc... As for Sumatra Island, we have lots of spectacular species: sumatrana, beccariana, eustachya, gracilis, ampullaria to name a few lowlanders to talangensis, izumiae, aritolochoides, lingulata, jamban, ovata, etc...for the highlanders to ultrahighlander CMIIW.
