|discussion=<p>The densely branched stems of Echinocereus stramineus form hemispheric mounds bristling with unusually long, yellow-tinted spines, thus appearing like a heap of straw; old clumps of these cacti are unique visual dominants on many rocky slopes in the Chihuahuan Desert. The delicious ripe fruits of this species are much larger than those of E. enneacanthus, and may be the largest fruits in the genus. Rare white-flowered individuals occur.</p>
