petiolule การใช้
- A pulvinus on a petiolule is called a pulvinulus.
- Each leaflet may be attached to the rachis by a short stalk called the petiolule.
- They feed on the leaflets and bore into the petiolules of their host plant from within this shelter.
- The leaf margin may be entire or sometimes toothed in coppice shoots, while petiolules are virtually absent.
- The leaves are digitately compound with from 3 to 5 leaflets, with entire, ciliate margins and petiolules of only 10mm or less in length, while the petiole may be up to 60mm long.
- Leaf blades are approximately 800 mm wide, split into 12 segments, these with straight sides; middle segment not wider than the others ( and not split with no petiolules ) 465 mm long, 65 mm wide at the apex; indentations leading to adaxial folds 5 mm deep, those leading to abaxial folds 3 mm deep, indentations deeper on lateral segments.
