Abstract
The present study investigates the anatomical and morphological
characteristics of four Taenitis species sampled from several localities in
Peninsular Malaysia, namely Taenitis blechnoides, T. interrupta, T. dimorpha and Taenitis sp. The morphological and anatomical characters were observered with compound and dissecting microscopes, and
sliding microtome. The species exhibited varying frond sizes (length and width)
and positions of sori. Conversely, all the species
showed common short creeping rhizomes with black hairy scales, scales at the
base of stipes, U-shaped steles, simple trichome,
sclerenchyma cells under the epidermis on stipes and rhizomes, polocytic stomata, and sinuous anticlinal walls. Morphologically, the frond form of Taenitis sp. is distinct from the other Taenitis.
Thus, the
species could be a new record for ferns in
Peninsular Malaysia. However, molecular studies are required to confirm this.

Abstrak
Kajian ini menentukan ciri anatomi dan morfologi empat spesies Taenitis yang diambil dari beberapa lokaliti di Semenanjung Malaysia, iaitu Taenitis blechnoides, T. interrupta, T. dimorpha dan Taenitis sp. Penelitian ciri morfologi dan anatomi dilakukan menggunakan mikroskop majmuk, mikroskop pembedahan dan mikrotom gelongsor. Spesies yang dikaji menunjukkan pelbagai saiz fron (panjang dan lebar) dan kedudukan sorus. Sebaliknya, kesemua spesies yang dikaji menunjukkan ciri rizom menjalar pendek dengan berwarna kehitaman di bahagian pangkal stip, stel berbentuk ‘U’, trikom jenis ringkas, sel skelerenkima di bawah lapisan epidermis pada stip dan rizom, stomata jenis polositik dan dinding antiklin jenis sinuos yang berliku. Bentuk fronTaenitis sp. berbeza daripada spesiesTaenitis yang lain. Oleh itu, spesies ini berkemungkinan merupakan rekod baharu paku pakis di Semenanjung Malaysia. Namun kajian lanjutan dalam molekul diperlukan untuk mengesahkannya.
