I have got quite a few different clones of albomarginata but here are three of my favourites.
Kuching spotted (MT)
The upper pitcher's peristome is reddish brown and the body is speckled red.
purple black (EP)
The upper pitcher's peristome becomes black.
An immature upper pitcher (left) with peristome still red and body speckled red.
The mature upper pitcher's peristome is black and the body is speckled purple.
This clone's pitcher is more stout and the peristome is wider.
