from water!

The answer to this riddle was "Parakeelia." This is a local, presumably
native, name in Central Australia for a most wonderful and useful plant.
A specimen brought back by me from this locality was identified at Kew as
CALANDRINIA BALONENSIS. This plant grows close to the ground in little
bunches; in place of leaves it has long, fleshy projections, like
fingers, of a yellowish-green colour. From the centre grows a pretty
little lilac flower at the end of a single thin stalk. The fingers are
full of watery juice and by no means unpalatable. We tried them raw, and
also fried in butter, when they were quite good eating. The plant is
greedily devoured by stock of all kinds, and in dry tracts in Central
Australia has been the means of saving many head of cattle. As we found
it, it was not easily got hold of, for invariably it grew right in the
centre of a hummock of spinifex. At first the camels, not knowing its
properties, would not risk pricking themselves, but after we had shown
them, by clearing away the spinifex, how nice it was, they did not
hesitate to plunge their soft noses into the spiny mass, with what good
effect I have already described. Indeed, this plant is a wonderful
provision of nature, and compensates a little for the hideous sterility
of the country. I am not wide of the mark when I say that given
"parakeelia" every second night or so a camel would never want to drink
at all, though it is not really as serviceable as water--not having the
same lasting effect. A similar plant, also found in Central Australia, is
"Munyeru." In the centre of this a little bag of black seeds grows;
these seeds are crushed and eaten by the natives. Munyeru, Breaden tells
me, is quite a good vegetable for human consumption. Why the locality of
this well, "Warri Well," should be specially favoured by the growth of
parakeelia I cannot guess.
