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 ...

Leaf Physiology and Anatomy by Photoacoustics
Second International Meeting on Photoacoustic Spectroscopy, 1981Plant leaves are generally composed of about seven to eight layers of cells: an upper epidermis layer, two to three layers of elongated palisade cells, about three layers of spongy cells with large intercellular air spaces and a lower spidermis. The epidermis layers contain pores (stomata) with a mechanism to open or close them, controlled by adjacent ...

Leaf Anatomy in Crocus (Iridaceae)
Kew Bulletin, 1990The leaf anatomy of Crocus L. (Iridaceae-Ixioideae) is described in the context of the systematics of the subfamily. Leaves of most species have a distinctive cross-sectional outline, with a central square or rectangular 'keel', and two lateral 'arms'. C. carpetanus differs markedly in that it lacks a single central keel, and has several surface ridges.

Anatomy of non-uniform leaf photosynthesis
Photosynthesis Research, 1992Since 1986, non-uniform photosynthesis over the leaf area that may be attributed to patchy stomatal closure, has been an important issue in stress physiology of photosynthesis. In this review, I first outline the gaseous environment within the intercellular spaces, because this is the most fundamental background of this problem.

Leaf and Stem Anatomy of Tradescantia fluminensis, Vell.
Journal of the Linnean Society of London, Botany, 1925Summary. 1The investigation was started in the hopes of throwing some light upon the problem of sap supply to the upper parts of leaves which grow by a basal meristem, but has been extended as a developmental study of the shoot. 1The scattered bundles of the stem may be classified into four groups–(a) medullary, (b) perimedullary, (c) cortical, (d ...

Ontogeny of Leaf Morphology and Anatomy
1985Because of their role in intercepting and absorbing radiant energy, and transforming it to energy of organic substances through the complex process of photosynthesis, leaves are the most important organs for plant production, and hence for agriculture.

LEAF ANATOMY OF WELWITSCHIA. I. EARLY DEVELOPMENT OF THE LEAF
American Journal of Botany, 1958MATERIALS AND METHODS.-The material, collected in South-West Africa or grown in Berkeley, California, is the same as that used in the seedling study (Rodin, 1953b) and the same techniques have been applied. Approximately 24 seedlings were used in this investigation.
