Geometric morphometric studies have become well
established in systematics in recent years due to their holistic and numerical
nature, which makes them less prone to errors than manual techniques and is
fast and efficient when dealing with large numbers of specimens. In systematic
botany, leaf morphology studies have so far benefitted from these methods the
most. The aim of this work is to determine the usability and usefulness of
shape analysis in leaf cross sections of crocuses. The leaves of Crocus L. are known to have a unique
shape in cross-section and their morpho-anatomical features, including keel
shape, arm length and arm curvature, are used in systematic studies. In line
with this purpose we sampled and analyzed all known populations of Crocus mathewii Kerndorff & Pasche, a
rare and endemic taxon from the Western Taurus region (Turkey). Morphometric
studies were conducted using MASS and PAST computer programs. Classical anatomical
characters and measurements were also used with PCA in order to compare the two
methods. Elliptic Fourier analysis was found to be useful in Crocus leaf sections when dealing with
great number of specimens.
