A leaf (PL: leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the ...

Abstract. A new species of Lepanthes from north-western Ecuador is presented here.Lepanthes mashpica is similar to L. satyrica, with a long, descending, triangular process of the body of the lip but different in the simple and acute appendix versus the vertically bilobed appendix of L. satyrica. The species was found growing in several locations of Mashpi Reserve, a low-land cloud …

Plant structure. Kalanchoe beharensis is an evergreen shrub, 3–5 ft (1–2 m) tall. The stem is about 1.5 m (4.9 ft) long, slender and knotted. Leaves are olive green, triangular-lanceolate shaped, decussately arranged (pairs at right-angles to each other) with leaf margins that are doubly crenate (crinkled). Each leaf is about 10 cm (4 in) long and 5–10 cm (2–4 in) wide.

Aug 30, 2022 · An ovate leaf’s shape is much wider at the base on either side of the midrib. As it gets farther away from the branch, it tapers towards the apex of the leaf. A genuine ovate leaf will have a length-to-width ratio that ranges from 1.5:1 to less than 2:1. Species with ovate leaves include blue beech, elm trees, and dogwood.
