Use "spinifex" in a sentence
"The slopes of the tableland were grassed with spinifex, which is almost worthless."
"Triodia: Sometimes called spinifex, or porcupine grass, is a true desert plant, and at the end of each leaf it is so armed with short prickles that horses dread going through it, and stock never touch it except when it is very young or they are starving."
"The only game found in the spinifex is a kangaroo rat, commonly called the wirrup; but in the grassy openings there are many kangaroos, and often emus, also a rat known as the wurrung."
