and the colour of the leaves, which are pale yellow at the margins.
Photo 2. Symptoms of Banana bunchy top virus. Notice the leaves are upright, stunted and tend to cluster in the throat of the plant; leaves like this are said to be "choked", and give the bunchy top symptom.
Photo 3. Underside of a banana leaf showing veins that have dark and light areas (dots and dashes) along them. The veins near the midrib bend down,"hooking" into it.
