Brit.

/prəʊˈkambɪəm/, U.S.

/proʊˈkæmbiəm/

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: pro- prefix², cambium n.

Etymology: < pro- prefix² + cambium n., after German Procambium ( J. von Sachs Lehrb. der Bot. (1868) 90; now also Prokambium).

Botany.

Primary meristematic tissue that differentiates into primary vascular tissue (xylem and phloem).

1872 Philos. Trans. (Royal Soc.) 162 311 In these plants the young aërial buds and the tips of the young leaves and roots severally contain the special homogeneous parenchyma to which Sachs has given the name of ‘procambium’.

1912 S. J. Record Identification of Econ. Woods of U.S. 11 Below the apex the primordial meristem becomes differentiated into three distinct parts, viz., (1) the protoderm at the outside, (2) the procambium strands, and (3) the fundamental or ground meristem.

2005 Curr. Opin. in Plant Sci. 8 512/1 Cells in the procambium can differentiate to form either part of the phloem or part of the xylem.
