woo hoo! found this sensitive 'ranked' wildflower species right in my veggy garden hiding behind the bush beans.
I'm curious. Did you measure the petal lengths?
Identification Tips: Oxalis suksdorfii is most closely related to
O. stricta, O. dillenii, and O. corniculata. These species can be
distinguished by their petal length and number of peduncles. The
petals of O. suksdorfii are ½ to ¾ in. (12 to 20 mm) long, and it has 1
to 2 flowers. The petals of O. stricta, O. dillenii, and O. corniculata are
1/8 to ¼ in. (4 to 9 mm) long, and they have 1 to 7 flowers.
Cool photo of the pink ladyslipper Cedars!
Violets are tricky. Between adunca and odorata, I'd say you are correct Turtle.
