The following images of the specimen above zoom in on an area of transition between vascular tissue at the center of the stem and the root mantle. The first three images were taken with a Canon PowerShot SD770 IS Digital ELPH 10.0 MEGA PIXELS, cropped and resized in Adobe Photoshop Elements 2.0. The images were taken in sunlight outside.

In the image above one can see adventitious roots from the inner part of the mantle. Proliferating epidermis and cortical tissues appear to "flow" around the individual roots which they interconnect.

The close-up below zooms in on a single rootlet in the photo above and was taken at 30x using a Swift M29TZ Zoom Stereo Trinocular Microscope and a Moticam 2500. The microscopes upper halogen light was used for illumination. The image was cropped and resized using Adobe Photoshop Elements 2.0. The rootlet measures 2 mm in diameter. The largest xylem cells making up the star shaped center measure 100 micrometers in diameter.
