This article presents a novel method for classification of plants using their leaves. Most plant species have unique leaves which differ from each other by characteristics such as the shape, colour, texture and the margin. The method introduced in this study proposes to use two of these features: the shape and the texture. The shape-based method will extract the contour signature from every lea...

Taro is an important crop species in Côte d’Ivoire. It cultivated for its tubers and leaves. But knowledge genetic diversity differentiation are very weakly documented. Several morphological types found rural area, but their identification not clear, agronomic potentiality underexploited. In this context we initiated a survey collected 213 accessions from 14 growing regions of The was evaluated...

Present paper deals with the macroscopic, microscopic, preliminary phytochemical and anti-inflammatory activity studies of the leaves of E.nivulia Buch. Ham. Leaves are linear oblanceolate or spathulate in shape with narrowly by cunative base. A pair of spins inserted on flat brown or black corky areas of the stem. In the mid rib non-articulated laticifers are distributed around the vascular bu...

Angiosperm leavesmanifest a remarkable diversity of shapes that range fromdevelopmental sequenceswithin a shoot and within crown response to microenvironment to variation among species within and between communities and among orders or families. It is generally assumed that because photosynthetic leaves are critical to plant growth and survival, variation in their shape reflects natural selecti...

We are grateful to Givnish and Kriebel (2017) for providing a thorough review of the arguments that have been advanced to explain the latitudinal gradient in leaf form. Th eir paper was motivated by our recent “On Th e Nature of Th ings” essay presenting the “bud packing hypothesis” (BP) as an alternative explanation for why leaves in the temperate zone are so oft en toothed or lobed ( Edwards ...

Leaves develop as planar organs, with a morphology that is specialized for photosynthesis. Development of a planar leaf requires genetic networks that set up opposing adaxial and abaxial sides of the leaf, which leads to establishment of dorsoventral polarity. While many genes have been identified that regulate adaxial and abaxial fate there is little information on how this is integrated with ...

The leaf shape is an important taxonomic character. Compared to the classic morphological leaf features such as veins, margin indentations, sinuses, etc., the shape is simpler to obtain by using the 'magic wand' or other contouring tools that are available in most of imaging applications. The only exception is when leaves develop large lobes that get in touch or overlap each other, as the prese...
