Supplementary Table 2 from Rapid diversification of vascular architecture underlies the Carboniferous fern radiation

Table S2: The loadings that best describe each of the 5 clusters of vascular architecture. MeanIn Category, sd in category describes the mean and standard deviation of the loading value for the specific vascular architecture. Overall mean and Overall sd describes the mean and standard deviation of the loading for all individuals in the analysis. The p.value denotes whether the mean loading for the specific vascular architecture is significantly different from the overall mean.
