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

large numbers of individuals of this taxon were found quite by accident in an area heretofore unknown for this taxon. Some individuals were found growing in the road with tire tracks 'over them'.
