Galium obtusum, the bluntleaf bedstraw, is an herbaceous plant species in the family Rubiaceae. Bluntleaf bedstraw is a wildflower native to eastern North America. Introduction The bluntleaf bedstraw (Galium obtusum) is a wildflower that starts growth in spring and blooms in the summer, this plant is relatively small only growing between 8 and 30 inches in height and spreads roughly around a foot in area. One notable characteristic of Galium obtusum is its blunt leaf tips hence the common name Bluntleaf Bedstraw.

Leaves that whorl tend to be the same size or very close in size. Taxonomy As of 2013 there are around 630 species of Galium. Rubiaceae is the family that Galium obtusum is placed. The order of this species falls in Rubiales and there are two subspecies Galium obtusum Bigelow subsp. filifolium (Wiegand) Puff and Galium obtusum Bigelow subsp. obtusum. Galium obtusum is the first species to diverge in lineage. This plant has very different leaves when compared to other bedstraws as its leaves are rounded at the ends, most other bedstraws have leaf tips forming sharp apices meaning that they form a point at the leaf's end.
