SKINNER'S FALSE FOXGLOVE
B. S. Slaughter
reticulate venation on calyx
Usually considered a rare species, and certainly so in the Great Lakes region. First collected from an open sandy depression in Algonac State Park, St. Clair Co. (W. W. Brodowicz in 1988, MICH).
Well developed stems of this species are very narrowly winged on the four corner angles, with a pale rounded ridge on each side between them. The corollas of A. skinneriana are very pale, with scarce if any evidence of spots or lines, in contrast to the deeper pink ones of A. gattingeri, with red spots and two yellow lines in the throat. Agalinis skinneriana is often unbranched, and even in robust branched specimens, the branches are strongly ascending, becoming more or less parallel to the stem. In A. gattingeri, plants are commonly branched, and the branches are spreading, with the flowers near the ends, appearing terminal at a glance.
The branching and flowering characters that help to distinguish this from A. gattingeri are rather obscure, and depauperate, unbranched plants of A. gattingeri may resemble A. skinneriana. However, in the field, they have different aspects, evident when they grow together.
