Allometric relationships between stem biomass (B) and stem diameter (D) and length (L) in E. multiflora (n = 40) and G. alypum (n = 100)

	Species	Allometric relationship	r2	P
Stem diameter	E. multiflora	log B = −0·506 + 2·324 log D	0·947	<0·001
	G. alypum	log B = −0·897 + 2·619 log D	0·926	<0·001
Stem length	E. multiflora	log B = −4·738 + 2·086 log L	0·839	<0·001
	G. alypum	log B = −5·408 + 2·280 log L	0·640	<0·001
Stem diameter + length	E. multiflora	log B = −1·73 + 1·79 log D + 0·57 log L	0·961	<0·001
	G. alypum	log B = −2·11 + 2·23 log D + 0·54 log L	0·942	<0·001
