made up of numerous glomerate cymes, crowded in the axils of the 

 linear cauline leaves, which much exceed them in length. Limb of the 

 corolla 4 lines in diameter, its lobes rounded. Nutlets smooth and 

 shining, the lower half of the back convex, the upper depressed on the 

 sides, leaving a central vertical ridge. According to Dr. Gray this plant

 has passed for a form of E. glomeratum, DC, but seems more nearly 

 allied in its fruit and habit of growth to E. leucophaeum, A. DC. (Myoso- 

 tis leucopJma, Dough, in Hook. PI. Bor. Am. 2. p. 82. 1. 163,) and I have 

 ventured to give it a name.
