This is a reference to the shape of a histogram of tree lengths that can be produced after searching through treespace. Studies of random datasets have shown that the distribution of tree lengths is approximately normal, whereas in general datasets with a reasonable amount of signal have few shortest trees and few trees nearly as short. There is a G-statistic for the skewness of a histrogram.
