Century Dictionary and Cyclopedia
    • n sclerenchyma The hard sub stance of the calcareous skeleton or corallum of sclerodermic corals, a proper tissue-secretion or calcification of the soft parts of the polyps themselves.
    • n sclerenchyma In botany, the tissue largely composing the hard parts of plants, such as the shell (endocarp) of the hickory-nut, the seed-coat of seeds, the hypoderma of leaves, etc. The cells are usually short, but in some cases they are greatly elongated, as in the hypoderma of leaves; they are sometimes regular in outline, but most frequently they are very irregular. By many later, especially German, writers the term has been transferred to the hard bast or liber, a tissue of plants composed of cells whose walls are thickened, often to a very considerable extent. It is also used by some authors in a more extended sense, to include all sorts of lignified fibrous cells or cell-derivatives.
