Also called duramen . </Li> <Li> Internode--spaces between the nodes . </Li> <Li> Latent buds--An axillary bud whose development is inhibited, sometimes for many years, due to the influence of apical and other buds . Also known as a dormant bud . </Li> <Li> Late wood--The portion of the annual ring that is formed after formation of earlywood has ceased . </Li> <Li> Lateral buds--A bud located on the side of the stem, usually in a leaf axil . </Li> <Li> Leaf--the photosynthetic organ of a plant that is attached to a stem, generally at specific intervals . </Li> <Li> Leaf axils--the space created between a leaf and its branch . This is especially pronounced on monocots like bromeliads . </Li> <Li> Leaf buds--A bud that produces a leafy shoot . </Li> <Li> Leaf scar--the mark left on a branch from the previous location of a bud or leaf . </Li> <Li> Lenticel--One of the small, corky pores or narrow lines on the surface of the stems of woody plants that allow the interchange of gases between the interior tissue and the surrounding air . </Li> <Li> Node--where leaves and buds are attached to the stem . </Li> <Li> Orthotropic growth--growth in a vertical direction . </Li> <Li> Chambered pith--A form of pith in which the parenchyma collapses or is torn during development, leaving the sclerenchyma plates to alternate with hollow zones </Li> <Li> Diaphragmed pith--Pith in which plates or nests of sclerenchyma may be interspersed with the parenchyma . </Li> <Li> Spine--an adapted leaf that is usually hard and sharp and is used for protection, and occasionally shading, of the plant </Li> <Li> Plagiotropic growth--growth inclined away from the vertical, inclined towards the horizontal </Li> <Li> Prickle--an extension of the cortex and epidermis that ends with a sharp point . </Li> <Li> Prostrate--growing flat on the soil surface . </Li> <Li> Rhizome--A horizontally orientated, prostrate stem with reduced scale - like leaves, normally growing under ground but also at the soil surface . Also produced by some species that grow in trees or water . </Li> <Li> Rootstock--the underground part of a plant normally referring to a caudex or rhizome . </Li> <Li> Runner--an above - ground stem, usually rooting and producing new plants at the nodes . </Li> <Li> Scandent--a stem that climbs . </Li> <Li> Pith--the spongy tissue at the center of a stem . </Li> <Li> Stem--vascular tissue that provides support for the plant, </Li> <Li> Stolon--a horizontally growing stem similar to a rhizome, produced near the base of the plant .
