Leaf Epidermis of the Rheophyte Dyckia brevifolia Baker (Bromeliaceae)

Some species of Dyckia Schult. f., including Dyckia brevifolia Baker, are rheophytes that live in the fast-moving water currents of streams and rivers which are subject to frequent flooding, but also period of low water. This study aimed to analyze the leaf epidermis of D. brevifolia in the context of epidermal adaptation to this aquatic plant's rheophytic habitat. The epidermis is uniseriate, ...

The Permeability of Non-stomate Leaf Epidermis to Carbon Dioxide.

It has been generally assumed that the exchange of gases between the intercellular spaces of leaves and the external atmosphere occurs to an appreciable extent only when the stomates of the leaves are open. However, attempts to correlate the observed rate of CO2 absorption either with the number of stomates per unit area or with stomate area have met with only limited success. VERDUIN (16) beli...

Leaf anatomy and its contribution to the systematics of Aechmea subgenus Macrochordion (de Vriese) Baker (Bromeliaceae).

The leaf anatomy of the species Aechmea subgenus Macrochordion was analyzed to obtain valuable data on their taxonomic delimitation and to identify anatomical adaptations to their respective habitats and habits. All leaves of these species are hypostomatic, and present: peltate trichomes on both surfaces; stomata sunk in epidermal depressions; small epidermal cells with thick walls and inclusio...

در ملانوم بدخیم Consumption of the epidermis

Background and Aim: Consumption of the epidermis (COE) is defined as thinning of the epidermis with attenuation of the basal and suprabasal layers and loss of rete ridges in areas of direct contact with malignant melanocytes. The aim of this study was to investigate the importance of COE as an additional diagnostic criterion for malignant melanoma and to evaluate its relationship to clinicopath...

Leaf epidermis images for robust identification of plants

This paper proposes a methodology for plant analysis and identification based on extracting texture features from microscopic images of leaf epidermis. All the experiments were carried out using 32 plant species with 309 epidermal samples captured by an optical microscope coupled to a digital camera. The results of the computational methods using texture features were compared to the convention...
