Abstract

Leaf anatomy and micromorphology characters of Cardiospermum halicacabum L. or locally known as peria bulan was investigated. Morphologically is a climber in the Sapindaceae, it has trifoliate leaves with minute stipules.

Results showed that this species has hypostomatic and anomocytic stomata, has non-glandular and glandular trichomes, and also secretory cells present in mesophyll sponge cells. Transverse sections of petioles and midribs showed that this species has petiole outlines with the presence of protruding structure (wings) on the left and right of adaxial side and U-shaped on abaxial side. Whereas in the midribs the protruding structures form into a hump on adaxial side and U-shaped on abaxial side.

Cuticle on the epidermal of leaf surface often showed the presence of striae in the epiphyll part and usually radiating from the stomata.

The results obtained in this study can be used to differentiate the leaf anatomy and micromorphology characters of Cardiospermum halicacabum from other geographical regions.

Hypostomatic, superficial, sparsely scattered on the abaxial epidermis surface. Elliptical shape. Stomata size: L (11.48–16.12 µm) xW (9.01-10.02 µm).

The combination of stomatal types, anticlinal wall patterns and stomatal index proved to have taxonomic value

Abstract –

Sapindaceae is one of the main angiosperm plant families and this family includes 150 genera with ca. 2000 taxa that widespread in the tropical and subtropical regions of the world.

A study on the variation of stomatal types and anticlinal wall patterns was undertaken on 43 taxa belonging to 19 genera of Malaysian Sapindaceae.

Results have shown that there were four types of stomata present and four types of anticlinal wall patterns exist in Malaysian Sapindaceae taxa. Stomata types consist of tetracytic, paracytic, staurocytic and anomocytic stomata.

Whilst for the anticlinal wall patterns vary from sinuous, wavy, slightly curvy and straight patterns. A majority of species were having homostomatic and hipostomatic stomata, except for Lepisanthes amoena, Mischocarpus sundaicus, Nephelium cuspidatum var. robustum, Nephelium cuspidatum var. eriopetalum and Trigonachras acuta which have heterostomatic stomata feature.

Stomatal index (SI) ranging between 2.5% – Litchi chinensis and the highest found in Dodonaea viscosa with SI 25.98%.

The combination of stomatal types, anticlinal wall patterns and also in the stomatal index proved to have taxonomic value especially in assisting species identification for Malaysian Sapindaceae members.
