Xylem vessel and ray dimensions of Afzelia bipindensis and A. pachyloba. The numbers indicate Tervuren xylarium specimens: Tw62 (1); Tw27823 (2); Tw52893 (3); Tw45117 (4); Tw52910 (5); Tw52902 (6); Tw52911 (7); Tw52906 (8); Tw3901 (9); Tw52907 (10). Ray width: A. pachyloba: mean = 39.8 µm, variance 118.8, n = 306; A. bipindensis: mean = 38.5, variance = 106.4, n = 423. Ray height: A. pachyloba: mean = 238.7 µm, variance = 2730, n = 292; A. bipindensis: mean = 277.4 µm, variance 5893, n = 477. Vessel tangential diameter: A. pachyloba: mean = 180 µm, variance = 2057, n = 225; A. bipindensis: mean = 211 µm, variance 2828, n = 280. The raw data is shown in Zenodo repository (Kitin et al 2020). Achieving a species-level identification accuracy is challenging because of the within-tree and between-tree variabilities of the quantitative characters (see Discussion)
