Western-wood Acacia:  Same as Gidya.

Roley-poley:  An annual salsolaceous plant.  It grows in the form of a large ball, several feet high, on rich soil.  It withers in the dry season, is easily broken off and rolled along by the winds, hence its name.

Cotton Vine:  A plant, probably the same cynanolium of which the unripe milky pod is eaten by the natives about Lake Torrens.

Polygonum cunninghami:  A very wiry shrubby bush, which always indicates that the ground where it grows is liable to be occasionally flooded.  It is the same as the one from the Murray and Darling.

Mulga Scrub (an Acacia):  This is frequently mentioned by Stuart; its botanical name is not known.

As it is desirable that all the routes from the Darling towards the Barcoo River should be known the following letter from Mr. Neilson is appended.  The route he describes is almost on a direct line from Mount Rankine to Carpentaria.

Kennedy’s XIX Camp, River Warrego, May 22 1862.

Dear Sir,

Agreeably to your request I beg to furnish you with a few memoranda of a journey made by Messrs. H. and F. Williams and myself from Mount Rankine on the Darling towards Cooper’s Creek.  We left the Darling on the 22nd of June 1861, and after crossing the Talywalka Creek at six miles camped on Mulyoh Spring, course north-west by west distance twenty-five miles.  Our next day’s journey was to Wentholey on the Paroo Creek upon the same bearing and a distance of forty miles.  We then followed the Paroo Creek upward on a general course of north by east half east to the 29th parallel, when we struck out to the north-west, and on rising the range saw a large sheet of water.  Camped upon it.  It proved to be a lake of about twenty-five miles in circumference and very shallow.  Our distance travelled, twenty-three miles from the boundary.  Next day followed the same course and camped at thirty miles on a large clay-pan.  Followed on the next day, and at ten miles came on a Boree Creek with water.  Followed on bearing to the northward of north-west about half a point, and camped on a lateral creek containing pools of water and polygonum flats, and on examining the bed of the creek found some crayfish-eyes, and judged to be in the vicinity of a large water.  Distance travelled twenty-six miles.  Next day followed the creek on a north-north-west bearing, and at eleven miles came to a large creek running rapid and having flooded flats extending two miles from its bed, and bearing marks of very high floods.  We crossed the creek and extended our journey about fifteen miles to the west; the country being cut up by creeks not then flooded but bearing evidences of high floods.  Our rations being short we turned back.  From this point I consider our position to be within about thirty-five miles of Cooper’s Creek.  We followed the creek we left, running down for about fifty miles on a south-west by south
