| Lower orders for Didi | 26.90% | 59.50% | 2.21 |
| Lower orders for Cula | 20.45% | 35.93% | 1.76 |
| Lower orders for Paba | 28.70% | 43.58% | 1.52 |
| Lower orders for Acau | 44.99% | 38.76% | 0.86 |

a
Lower orders refer to root orders with no secondary xylem. See Table 1 for species abbreviation.
b
Ratio of CV is calculated by CV of density divided by CV of diameter.
