The young pitcher of this plant certainly looks like being on the veinless side. Veinless plants may look like f.heterophylla even in full sun, but the growth point is always reddish. Often young pitchers get this pinkish hue and reddish rim as shown in your photo. But veins and red diffusion may still develop. Just wait a few more weeks and you'll know for sure if it is a veinless or semi-veinless purpurea. Semi-veinless plants are not that well defined and cover many different looking plants between veinless plants and dark red plants. Environmental conditions also influence how strongly veins and red colour are expressed. Plants growing on peat (or in fens) get redder than those growing in Sphagnum.
You can only claim the plant is veinless if it proves to be under optimal or near optimal conditions rather than lack of sun, but given 10 hrs a day sunlight as you suggest, that should be enough to prove it one way or the other. It may prove to be veinless, if not, rather than describing it as semi veined, which is a bit of a misnoma (its either veined or not) perhaps lightly veined would suit. Cheers Steve

I got bored and wanted to take a few more photos when I came home. I would like to change the title of the post to just Sarracenia Purpurea but theres no edit button well what could you do. well here they are, the red colouration vanished and stayed more toward a greenish yellow and here are some of the new pitcher showing that red tinge
