310 THE JOUENAL OF INDIAN BOTANY.
Central India, Pachmarchi ; Peninsular India, Mysore, Palghat.
I can see no difference except in the numerous scapes between
this and E. longicuspis.
A. plant collected by Dr. Henry in Yuraan, No. 9443 in Herb. Calc. has smaller leaves more like those of E. odoratum and smaller heads. The involucral bracts are not reflexed, It may be a distinct species but is obviously closely related'to E. longicuspis.
30. E. atratum Koern., F.B.I, vi, 574, No. 10 ; Euhl. see p. 69
Stem up to 3 in. thickly covered with leaves. Leaves 1/4-1/3 in. wide at the base, then suddenly narrowed and bluntly linear, many nerved. Scapes solitary or few, 7-15 in. Heads 1/4-1/3 in. diam. In- volucre black. Floral bracts, white, concealed by the long-fringed male petals. Plate 26.
Ceylon, Adam's Peak.
There seems to have been some confusion With regard to this species. In Herb Ceylon is a sheet marked "Galagama February 1816, O.C. 932" and " C.P. 61 " and this last number is also borne by another sheet, ot the next species. Ruhland says the plant called atratum by Hooker in Fl. Ceylon is not Koerniche's species, but he does not say what is, and founds a new- species E. subglaucum on one of these former, which one I do not know. Koerniche in Linnaea xxvii p. 611 says the involucre is black.
31. E, ceylanicum Koern, Fl. Ceylon, v, 3, No. 4 ; Euhl. No. 128 ; (E. subcaulescens, Hook f. F.B.I, vi, 583 ; Euhl. No. 116) Simi- lar to E. atratum but the heads larger and involucre white or yel- lowish. Protruding male petals perhaps more conspicious. Plate 27.
Var. a. typica. Stem 0, leaves linear, 2-6 ins. by 1/10 ins., from a broader base.
Ceylon, Eliya lake.
Var. b. subcaulescens. Hook f. Stem to 2 ins. Leaves narrow 2-4 ins. by 1/6 ins., slightly broader at the base. Scapes stouter, but heads exactly as in the type species of which this appears to be more deve- loped or a form of drier positions. Plate 28.
Ceylon ; Horton Plain. This species is very closely allied to E. atratum, and if the involucral bracts of the latter vary, as stated by Hooker in Fl. Ceylon from black to yellowish, all these forms should be included under one species- The only other real distinction given by Hooker is that the lower floral bracts of E. atratum are very shortly cuspidate, the upper being acute (as in E. ceylani- cum). Ruhland makes three species of these forms.
32. E. robustum Steudel, F.B.I, vi, 572, No. 5 ; Euhl. No. 120. Stem short and stout to as much as 1 in. in thickness: thinner and branched in var. b. Ls. up to 12 in. by 2 in., many nerved, glossy, coriaceous. Scapes to 24 in. Heads l in. Involucre white or
