Patapsco SP--Daniels, Howard Co. MD
Growing in crevices on a talus slope. This area was a gravel quarry historically. Presumably, this species must have occurred on naturally exposed rock formations prior to the blasting. Two distinct patches found, appearing to have anywhere from 3-8 individuals.
@brucen I don't think this species has been recorded here before, so I imagine someone at Willamalane would probably be interested to know about it.
