Ceylon : Ilorton Plain. Adam's Peak. There is no real difference except in the stem and its branching from E. robust am. A piece of the Ceylon plant is indistinguishable from a not very robust Nilgiri one. I have therefore no hesitation in uniting this as a variety to E. robustovi, though Hooker founded a new species for it, and Ruhland followed Thwaites in calling it var major of E. atratum. The fresh flower heads have the scent of a Chrysanthemum.

Assam ; Khasia ; Bengal. Some of the heads have a fringe of protruding male petals as in E. longi- cuspis, but because of the broad leaf-bases I am inclined to regard this as more nearly related to E. ceylanicum.

Both involucral and floral bracts scarious without any trace of dark colour, and tending to become hairy and acuminate. Receptacle villous. Flowers perfect or more often very small and reduced by omission of one or more parts. Stem in all disciform and leaves glabrous. Involucre hairy.
