In a more recent book written by Slack (I think about 1986) he
describes the cross between S.purpurea venosa and S.alata. It's known as
S.x exornata. He doesn't have any pictures and the description only
states that pitchers are lighter in colour than S. x catesbaei (S.flava X
S.purpurea) and flowers are a 'delicate pink'. According to Schnell (1976)
S.purpurea venosa does cross over into the range of S.alata. In southern
locations, both flower in March to April. So, artificial crosses have been
made and hybrids have most likely naturally occurred as well. As far as
what they look like, I can't say. However, I'd venture to guess that they
are similar in appearance to S. x catesbaei (Schnell's book shows this one)
Whether it's horrendous or not is in the eye of the beholder ;-). Good
luck hybridizing!
