combining form of Gr. ϕελλός cork. ˈphelloderm Bot. [Gr. δέρµα skin], a layer of parenchymatous cells containing chlorophyll, formed in the stems of some plants from the inner cells of the phellogen; hence phelloˈdermal a., of or pertaining to the phelloderm. ˈphellogen Bot. [see -gen], the layer of meristematic cells from which the cork-cells are formed, the cork-cambium; so phellogeˈnetic a., producing cork, of the nature of phellogen; phelloˈgenic a., of the nature of or pertaining to phellogen.
1875Bennett & Dyer Sachs' Bot. 90–1 In some cases the phellogen of the periderm gives rise not only to cork⁓cells..but..[to] permanent parenchyma-cells containing chlorophyll..which Sanio terms the suberous cortical layer (Phelloderm)... In such cases the phellogen lies between the periderm and the phelloderm, the outer of its daughter⁓cells producing cork-cells, the inner phelloderm. 1884Bower & Scott De Bary's Phaner. 545 The periderm consists of the phellogenetic meristem [= phellogen], and the tissues..derived from it, which..include a..stratum of Cork-cells..to which usually, but not always, phellogenic or peridermal parenchyma, the Phelloderm of Sanio, is added. Ibid. 549 The number of the phellodermal layers..is in most species very small, in comparison with the cork-layers which appear in the same space of time. |
