1917 Jrnl. Forestry 15 179 The parenchyma is strikingly metatracheal in its distribution.
1950 C. R. Metcalfe & L. Chalk Anat. Dicotyledons I. Introd. p. xxiv Bailey suggests that the word ‘metatracheal’ should be dropped, owing to the different senses in which it has been used, in favour of ‘banded’.
1970 K. Wilson & D. J. B. White Jane's Struct. Wood (ed. 2) vi. 116 Apotracheal parenchyma may occur as..tangentially arranged sheets of cells..or in more extensive tangential bands... The two latter types are sometimes referred to as metatracheal parenchyma but this term is better avoided.
