lenticel

1. Lenticel
   lĕn"tĭ*sĕl (Bot) One of the small, oval, rounded spots upon the stem or branch of a plant, from which the underlying tissues may protrude or roots may issue, either in the air, or more commonly when the stem or branch is covered with water or earth.

1. (n) lenticel
   In botany, a lens-shaped body of cells formed in the periderm or corky layer of bark, which by its enlargement soon ruptures the epidermis, or the older corky layers where such are present. Outwardly lenticels appear in the earliest stage merely as brighter spots, then as oval warts, becoming two-lipped; while in some plants they widen with the growth of the stem into transverse striæ. They are produced either beneath a stoma or group of stomata or independently. Their intercellular spaces are in communication with the outer air, and they thus serve the purpose of cortical pores, which name they sometimes bear. The outer (not corky) cells of a lenticel are termed packing or complementary cells; the inner (corky) cells have been called phelloderm. Lenticels occur on the great majority of stems which produce bark in annular layers, also on the footstalks of many ferns.
2. (n) lenticel
   In anatomy, one of the small mucous crypts or follicles of the base of the tongue having the shape of a lentil; a lenticular gland.
