Leaf anatomy inTigridieae (Iridaceae)
Plant Systematics and Evolution, 1991Leaf anatomy is described in 32 species of 16 genera of the New World tribeTigridieae (Iridaceae, Iridoideae), including examples from both subtribesCipurinae andTigridiinae. Both plicate (pleated) and foliated (with flanges, or keel extensions) leaf types occur in both subtribes. However, amongTigridiinae, foliated leaves are restricted toTigridia and

LEAF ANATOMY IN SANSEVIERIA (AGAVACEAE)
American Journal of Botany, 1988Forty‐nine taxa of Sansevieria were examined to provide the first detailed description of leaf anatomy in the genus, as well as to determine the cellular organization of the water‐storage tissue present in the central mesophyll of all leaves.

Plant leaves provide the following main functions: (1) light interception and utilization of light energy for photosynthesis. This includes efficient light absorption under low and moderate light, while reducing excess light absorption under high light.

Leaf Axil Anatomy of the Araucariaceae
Australian Journal of Botany, 1987Well defined, persistent meristems, which possess neither a bud-like organisation nor vascular connections with the central vascular cylinder, were found in the apparently blank leaf axils of six species of Agathis and 13 species of Araucaria. In other conifers, leaf axils of similar external appearance are usually reported to lack, or gradually lose ...

Methods for the Study of Leaf Anatomy in Palms
Stain Technology, 1980Large size, hardness, combinations of thick-walled fibers and sclereids with thin-walled parenchyma cells, and the occurrence of silica, calcium oxalate, and tannins make anatomical preparations of palm leaves difficult. Samples for anatomical study should encompass one-half a pinna or a comparable portion from palmate and entire leaves including the ...

The green leaves of plants are photosynthetically active organs which are able to store absorbed solar energy in reduced organic compounds. These assimilates represent the pool for both energy and compounds which have to meet the plant’s requirements for growth and development.

American Journal of Botany, 1934
Ash. In Fraxinus peunsylvanica Marshall the essential structure of the embryonic leaf is revealed by a study of an unswollen leaf bu-id of late March. Each leaflet (fig. I, 2) consists of midrib and conduplicately folded wings. The wings are composed of a limiting layer of small, brick-shaped cells and a mesophyll region of cells of somewhat similar ...

Botanical Journal of the Linnean Society, 1975
A study of leaf anatomy of 24 genera of Cunoniaceae was made. The prevailing petiole vasculature is a nearly complete, usually adaxially flattened, medullated cylinder with the flat dorsal segment separated from the ventral arc. Medullary and cortical vasculation in Codia, Cunonia, Geissois and Pancheria is correlated with an increase in leaf ...

Leaf anatomy in the Tecophilaeaceae
Botanical Journal of the Linnean Society, 1986ARROYO, S., 1986.Leaf anatomy in the Tecophilaeaceae. Leaf anatomy of 12 species of the seven genera in the Tecophilaeaceae is described. Characters of taxonomic value within the family are the shape of epidermal cells, hairs and venation. Characters of diagnostic importance at the family level include the occurrence of raphide sacs in the mesophyll ...

Anatomy of Leaf Classification Techniques
2019 International Conference on Machine Learning, Big Data, Cloud and Parallel Computing (COMITCon), 2019There are number of categories of flora and fauna on earth. Vegetation is important for the existence of life. Leafs are the essential part of this vegetation. It is important to recognize them so that we can preserve them for the future. Classification is a process to distinguish the leaf on the basis of features that are extracted from the leaf ...
