The scientific name for this plant was for a great stretch of time "Aster Drummondii". However during the 1990's, taxonomists decided that the North American plants that had been formerly grouped in the genus "Aster" did not truly belong in that genus, and that it would be more accurate to move the American "Asters" into new taxonomic categories with new names. The name of the genus that this plant now belongs to was changed to "Symphyotrichum". Botanists have not all adjusted to this change, and so you will often find this plant referred to by its old name "Aster drummondii".

Note the thin, flat material extending out from the stem or petiole of the leaf. When the leaves of a plant display this characteristic, the leaves are said to be "winged". Occasionally, there are other parts of a plant that can show this "winged" characteristic as with the seeds of of the climbing false buckwheat (Fallopia scandens).

Dark Diamond Shaped Patches Near the Tip of the Phyllaries
Symphyotrichum drummondii - Dark Diamond Shaped Spots on Phllaries
In describing this species Dr. John Hilty on his web site "illinoiswildflowers.info" writes, "Individual phyllaries are 4-6 mm. in length, linear-lanceolate in shape, and light green, except for diamond-shaped patches of dark green near their apices." The diamond-shaped patches on two of the phyllaries have been outlined above on the right to help in understanding Dr. Hilty's description.

Phyllaries: Most flowers have a couple of small leaf-like appendages near where the flower stalk attaches to the stem. They are called "bracts". When there are a number of these bracts in a ring or whorl surrounding the base of a flower head, that group of bracts is referred to as the "involucre". The bracts of the involucre are also called "involucral bracts". Another name for a single involucral bract is "phyllary". These green phllaries are easily seen in the images just above. They are primarily seen as part of the flowers of the sunflower family (i.e compositae, Asteraceae family).
