Web the proposed morphological criterion is based on the microscopic observation of three main characteristics of guard hairs, namely (1) the cuticle pattern, (2) the medullar pattern (considering the medulla on all the length of the shaft) and (3) the medullar margins (considering the medulla at the thickest part of the shield region). This is known as the distal (toward the tip) end, while the proximal (toward the root) end is the point from which the hair grows. The medulla is a loosely packed, disordered region near the centre of the hair surrounded by the cortex, which contains the major part of the fibre mass, mainly consisting of keratin proteins and structural lipids.
