Summit of Mount Roraima, 8600 ft., McConnell & Quelch, 496. 
Allied to Xyris Seubertii, Nilss., but distinguished by its smaller size, lacerated bracts, 
and the glabrous or very minutely scabrid keel of the lateral sepals. "The broad bright 
brown bases of the leaves give the base of the plant a somewhat bulbous appearance.

The specimen collected by McConnell & Quelch consists of adult leaves and young 
plants, and that collected by im Thurn of the upper part of a flowering stem without 
leaves, so that this interesting plant is as yet very imperfectly represented in European 
Herbaria. !
