This may be considered a very pronounced stage in the lengthening of the 

 involucral bracts, begun in this series by var. Martiana of E.guinquangulare 

 and it might perhaps be more properly considered a variety of that species. 

 Its close relationship is shown in the very similar flowers, and the leaves 

 being red or drying red. Of the young heads the involucral bracts are not 

 much longer than the others, they lengthen with age,

 in diam., darker, and the involucral bracts more conspicuously reflexed.

This species exactly resembles E. Dianae, var triloboides in the Bombay 

 Presidency, except in the reduction in the latter of one female sepal. 



I am however uncertain of the identification of the sheets in the Calcutta 

 Herbarium, for Koerniche describes the female sepals as " carinatae, dorso 

 anguste spongioso alatae ", which they are not in these plants, yet there does 

 not appear to be any other plant from Bengal to answer to the rest of the 

 description.

 Stem O or elongate. Leaves 1 1/2-2 1/2 in. by 1/4 in., flat obtuse or 

 if submerged subulate. Scapes many 3-8 in. Sheath about as long as 

 the leaves. Heads 1/4 in., dark, globose. Involucral bracts dark or the 

 outermost or all pale, at length reflexed. Flora dark, obovate cuspidate, 

 sparingly hairy. Receptacle conical. Flowers normal, the sepals dark. 

 Female sepals in Ceylon two boat-shaped, one flat ; in South India 

 all equally boat-shaped. Male petals well developed, slightly unequal.

 elevations. Ceylon ; Newara Eliya and Highlands. Flowering in the 

 early part of the summer. 



The species varies considerably, possibly in relation only to the environ- 

 ment. The plants are nearly always gregarious, but sometimes in dense 

 clumps, the soapes being numerous and tufted ; sometimes more or less free, 

 the scapes rising each from its own rosette of leaves. The leaves in the 

 type sheet are linear-oblong, about 1 inch by 1/10 inch, with scapes of 7 or 8 

 times as high, but I find every variation to leaves which may be as much as 

 half as long as the scapes ; they may also taper from a broad base evenly 

 to the tip or be narrow and acicular. They are usually thin or flaccid but 

 may be coriaceous. The heads typically gray with black involucre may be 

 almost white with colourless (pale) involucral bracts. The male petals are 

 not quite equal and in one Pulney plant one male petal of the lowest
