Female flowers: sepals two, white, concave, and somewhat 
keeled, glabrous, free, equal; petals four, linear-spathulate, the 
fourth smaller than the others, cohering at the base ; style one, 
with two filiform branches ; fruit globulose, minute, pale-brown, 
and shining. 
The species is anomalous in its tetramerous flowers ; whilst its 
glabrous flower-heads and the form of its floral leaves distinguish 
it, otherwise, from all Australian species. 
This is the first record of a member of the Order Eriocaulez in 
South Australia, though an undescribed species occurs in the 
Macdonnell Ranges in the extra-tropical part of the Northern 
Territory. 
The collector, Mr. Max Koch, supplies the following informa- 
tion as to its habitat, &c. :—‘‘About ten miles north from Trinity 
Well, on the main road to Innamincka, there is a large plain. 
Here and there are elevations of several feet high, densely 
covered with sedges: these elevations are the springs. Although 
they have never been known to go dry, yet not a large quantity 
of water seems to run away, and there is sufficient to water from 
one to several thousand sheep. It is in these springs that the 
Eriocaulon grows densely packed together, so that you may 
stand on ‘them; for beneath them is nothing but a deep bog. 
The water is glittering between the leaves; the top portion of 
them and the flower-heads are out of the water. The leaves are 
succulent, but rigid ; the part exposed to the light is of a pale- 
green colour, the lower part of the leaves is white.”
