Under a high magnification of 6486x, this 2006 scanning electron micrograph (SEM) depicted details of the morphologic surface characteristics of a "dandelion clock", from a Common Dandelion, Taraxacum officinale plant. The "clock" is the filamentous "puffball" of seeds arranged so as to be easily dispersed by the wind, or the breath of a curious child.Highlighted in this field of view was the remnant of a seed attachment, visible as a small cavitated nub. It is from these nub-like points that the "parachute"-equipped seeds detach, and are blown away, sometime over a distance of miles. Note that this is the second in a series of PHIL images, 8791-8796, in which the magnification is increased, thereby, providing greater and greater morphologic detail of the point of the developing seed attachment.Created: 2006

The "clock" is the filamentous "puffball" of seeds arranged so as to be easily dispersed by the wind, or the breath of a curious child.In this field of view the remnants of a seed attachment is visible as a small nub protruding from a small papule. It is from these nub-like points that the "parachute"-equipped seeds detach, and are blown away, sometime over a distance of miles.
