Koa Flowers & "Leaves"

Section through a koa "Leaf"

Image Split down the center to show that the "Leaf" is composed of two identical halves which have united to form a flat structure.

This is not entirely accurate because these are not true leaves, but it is included to convey the concept that leaves are like flattened stems.


The Veins in a Dicot become progressively smaller than the Midvein and branch at oblique angles. This is called Reticulate Venation.	The Major Veins in Monocots have a parallel orientation and smaller veins branch at right angles. This is called Parallel Venation.
Leaf Vascular Bundles (Veins) lie in one plane. They are surrounded by Ground Tissues. These internal tissues are covered by the Epidermis.

Dicot leaves have one large Midvein and many smaller Lateral Veins.	Monocots have many large veins of equal size. They also have smaller Veins of equal size that are not shown.
Midrib Section of a Dicot Leaf: One Large Vascular Bundle is visible. Section from the Blade: Note the relatively small Vascular Bundle (Vein) compared to the Midvein.	Corn Leaf Section (Monocot): . One large, and several small Vascular Bundles are visible. Sugarcane (ko) Leaf Section: This is similar to Corn. Section through a ki Leaf.
hau, 'ohi'a lehua and olona are Dicots.	hala, niu, ko, ki, pili & uki'uki are Monocots.
