Sorry for the poor quality photo, but I found this flower image in the corner of a photo I took of the Hill Country wild-mercury in April 2016. I had not noticed it at the time. The flowers are probably small - about 1/2". It looks like several blooms are growing radially from the end of a stalk. I'm not sure what it is but will watch for it to come back next spring. I'm guessing it's one of the blue-eyed grasses - Genus Sisyrinchium? Any other ideas?
Interesting 'elbow' joint in stem - though all specimens seemed to have them, the angle was more pronounced on some than others. Presumably an advantage in getting your flowers at the best possible angle/away from crowding?
Maybe a Sisyrinchium species? Half a dozen or so plants on exposed track side, growing amongst grasses and various broadleaf weeds.
Very short pale blue flowered species. Less common than the widespread tall white flowered sp.
NZ Flora Vol III lists it as S. 'blue'
Has it subsequently been named?
