 cose, max'cescent. Capsule 4-celled, 4-valved, loculicidal, dis-

 more highly coloured; while the Zeares. are ele.ijantly fringed with 

 hairs, and each hair is tipped with a gland. Growing along with 

 this and E. Tetralix, Mr. H. Watson finds at Truro a hybrid between

 with the leaves, pubescent ovary, and awned anthers of the next, but 

 varying in these respects.
