porcupine grass

One species, the porcupine grass, bears a name that does not belie its character.

St. spartea (porcupine grass) and other species are plentiful on the North American prairies.

The country we passed over was mostly scrubby sandhills, covered with porcupine grass.

For some miles we had seen very little porcupine grass, but here we came into it again, to the manifest disgust of our horses.
