Comparison study on morphology and anatomy characteristic of paracostus bullatus (Meekiong) and paracostus eburneus (Meekiong) from Bau, Kuching Division

The Order Zingiberales is a monocotyledonous plant that consists of eight families with 92 genera and approximately 2111 species. The Costaceae is one of the Zingiberales members that famously known as spiral gingers or locally known as Setawar hutan due to it having spiromonostichous leave arrangem...

The Costaceae is one of the Zingiberales members that famously known as spiral gingers or locally known as Setawar hutan due to it having spiromonostichous leave arrangement. This family recently has been revised and comprises seven genera, namely Costus, Chamaecostus, Cheilocostus, Dimerocostus, Monocostus, Paracostus and Tapeinochilos.

The morphological and anatomical characteristic of both species were determined. Observation and measurement of fresh collections were conducted to determine morphological characteristic of both species. The result showed both species clearly differed in term of leaves colour and floral characteristic. Leaf anatomical characteristic of both species were examined by using scanning electron microscope (SEM). The types of stomata on the adaxial leaf surface of both species were similar; paracytic, hemiparacytic and anomocytic but on abaxial leaf surface the types of stomata were differed; P. bullatus had paracytic, hemiparacytic and anomocytic while P. eburneus only had anomocytic. The longest average sizes of stomata on adaxial and abaxial leaf surface belong to P. bullatus. The longest average sizes of guard cells on adaxial leaf surface belong to P. eburneus while on the abaxial leaf surface belong to P. bullatus.
