α and Ω represent exponent and proportional coefficient of the relationship between vessel length and radius, respectively, defined by equation (16); lt, left. Research articles which Dawson et al. (1999) used for their estimation are partly common to our references (Horsfield 1978; Gan and Yen 1994; Jiang et al. 1994; Huang et al. 1996).

^1,2,3,4corresponded to the above‐mentioned Horsfield (1978); Huang et al. (1996); Gan and Yen (1994); Jiang et al. (1994), respectively. Sources of data were table 3 (Suwa and Takahashi 1971) and table 1 (Dawson et al. 1999), while ⁵means figure 4 (Dawson et al. 1999).
