that horses dread going through it, and stock never touch it except when

Gidya: A native name; the botanical name cannot be given without a
specimen.

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.
