Its severe fasciation, seems to originate from L.Longiflorum,.hells bells,Moby, thats some of the worst i've seen..i have an Aurelien 'Whistlin Dixie'-which is fasciated, but 'nothin' on those pics above,.,..,Judging of l.Longiflorum,[at shows] can get quite involved and nasty[mainly from entrants who have been disqualified] and most entrants know not to enter any fasciated stem,..,Im actually going to lug "whistlin Dixie' to a training course ,next week,.,.
