rhytidomen.

Brit.

/ˈrɪtɪdəʊm/, U.S.

/ˈrɪdᵻdoʊm/

Forms:

α. 1800s rhytidoma.

β. 1800s– rhitidome, 1800s– rhytidome.

Origin: A borrowing from Latin. Etymon: Latin rhytidoma.

Etymology: < scientific Latin rhytidoma (1837 or earlier), probably < Greek ῥυτίδωμα wrinkle, in scholia (medieval Greek or earlier) on Aristophanes Plutus 1052, 1066 < ancient Greek ῥυτιδοῦν to make wrinkled, shrivel up ( < ῥυτιδ- , ῥυτίς wrinkle < the same base as ῥυσός shrivelled, wrinkled (see Rhyssa n.) + -ις -id suffix², perhaps via a verbal adjective in -τός ) + -μα (see -oma comb. form). Compare French rhytidome (1855 or earlier).

Botany.

In a stem or root: the outer part of the bark, composed of the periderm and the layers of dead tissue exterior to this.

1838 London & Edinb. Philos. Mag. 12 56 Mohl, with other botanists, distinguishes these thick inner layers of the bark of the cork, which are formed in quite a different manner, and calls the inner layer the rugose bark (rhytidoma, from ῥυτις a wrinkle).]

1861 Amer. Jrnl. Pharmacy 33 506 Under the microscope, the periderma appears to be composed of several alternating layers of cork and parenchymal cells, and is therefore a true rhytidoma.

1875 Trans. Sc. Arboricultural Soc. 7 204 In some plants repeated layers of cork are formed deeper and deeper in the tissues, giving rise to the complex covering known to botanists as the ‘bark’ or rhytidome.

1896 W. R. Fisher Schlich's Man. Forestry V. 486 The Turkey-oak is used here and there in Austria for the production of bark, but on account of its forming, at an early age, a deeply-cracked rhitidome, or dead bark..it is of little value.

1908 W. R. Fisher Schlich's Man. Forestry V. 631 The dead bark, or rhitidome, arises from the above cell-forms by the scale-like formation of cork.

1953 K. Esau Plant Anat. xiv. 332 In some rhytidomes parenchyma and soft cork cells predominate; others contain large amounts of fibers.

1976 Flora 165 B. 326 Rhytidome composition..is considered also to be important for fungal bark infections.

2007 S. Afr. Jrnl. Bot. 73 451/2 For many species, the diagnostic characters of the rhytidome that determine bark patterns and types are only evident in older trees.
