Summary: | Acanthaceae family was used traditionally especially for native communities in
Peninsular Malaysia and also known as one of the potential plant families that
can cure diseases. Nowadays, many taxonomists also have difficulties in order to
identify species in Acanthaceae due to the morphological similarities and also
incomplete part of plants especially during identification process. But until now,
there is no comprehensive research especially for plant anatomy that has been
documented specific to Justicia gendarussa. J. gendarussa or known as ‘daun
rusa or genda rusa’ is useful for the treatment of inflammation, bronchitis,
vaginal discharges, eye diseases, dyspepsia (heartburn) and fever in Ayurveda.
Thus, the aim of this study is to identify the leaf anatomical and
micromorphological characteristics of J. gendarussa which can give additional
information for identification of species studied. Methods used were sectioning
using sliding microtome, epidermal peeling and leaf micromorphology method
using scanning electron microscope (SEM). Findings from this study showed that
the presence of collenchyma, sclerenchyma and mucilage cells have been
recorded either in petiole or midrib of the leaves. The anatomical characteristics
observed include petiole and midrib outlines, patterns of petiole and midrib
vascular bundles, presence of cystolith cells and presence and types of
trichomes. As a conclusion, leaf anatomy and micromorphology characteristics
are useful for additional data in identification of J. gendarussa. |
